Learn about methods for measuring hardness and the types, roles, and importance of testing machines.

[Reproduction Private Spring Preparatory School Lecture 2] The national standards for power test machines, testing methods, and reference pieces are firmly established in JIS!

The method of measuring hardness can now be done using testing machines as mentioned above, but what does the term "hardness" generally express? It often represents not only the degree of resistance to diamond but also characteristics such as being difficult to deform, hard to cut, prone to wear, and so on, which are commonly referred to as the mechanical properties of materials represented by the term hardness. Therefore, there is also a term "spring hardness," and nowadays, it conjures the image of a very strong and elastic spring. *For detailed content of the article, you can view it in the PDF.

The evolution from horse-drawn carriages to automobiles and the development and modernization history of Japanese spring manufacturing.

The evolution from horse-drawn carriages to automobiles and the development and modernization history of Japanese spring manufacturing.

[Reproduction of Private Spring Preparatory School Lecture 5] The rickshaw is also a benefactor for the spring industry! It also discusses the modernization of the spring industry.

The birth of Japan's spring industry, as mentioned last time, began with carriage springs. Even today, about a hundred years after the Meiji era, spring manufacturers are making a living from automobiles, which are a transformation of carriages, so we must be grateful to carriages. So, when did carriages, which have been so beneficial to Japan's spring industry, arrive in Japan? According to records, they began operating as public carriages in the Keihin area in 1869 (the second year of the Meiji era), and by the seventh year of Meiji, they were also operating in Tokyo. The number of these public carriages was only 319 in the eighth year of Meiji, but by around the time of the Russo-Japanese War, 38 years later, it had increased to 6,631, which is quite significant. *For more detailed information, please refer to the PDF.

The advancement of automobile development and spring technology, as well as innovations in materials and research progress in the late Taisho period.

The advancement of automobile development and spring technology, as well as innovations in materials and research progress in the late Taisho period.

[Reproduction of Private Spring Preparatory School Lecture 7] The Emergence of Automobile Springs, the Great Earthquake, and the Major Advancement of Automobiles! The late Taisho period was an era when spring research became full-fledged.

In the previous discussion, we talked about the beginning of domestic production of spring materials in the early Taisho period, and how various manufacturing facilities and testing equipment were established, leading to a significant leap forward. This time, let's continue with the late Taisho period. By the early Taisho period, the main railway lines were mostly constructed, and streetcars were operating in large cities; however, it was still the era of horse-drawn carriages and rickshaws. During this time, bicycles and automobiles were rapidly gaining popularity. However, while bicycles were becoming common, automobiles were still vehicles for the privileged class, and it was not yet the case that everyone could have one, as is the case today. Nevertheless, as vehicles changed, it was inevitable that springs would also change, and spring manufacturers had no choice but to start producing automobile springs. *For more detailed information, please refer to the PDF.

Difference between premium liquor and hard steel: Changes in properties brought about by alcohol content and carbon amount.

Difference between premium liquor and hard steel: Changes in properties brought about by alcohol content and carbon amount.

[Reproduction Private Spring Preparatory School Lecture 26] As the amount of carbon increases, both tensile strength and yield point increase!

In the last class, we learned that the properties of steel can change dramatically with just a tiny difference in carbon content, comparable to a speck of dust. For example, even when comparing mild steel and hard steel, the difference in carbon content is only about 0.5%. Just like how premium liquor with a higher alcohol content is more expensive, steel also becomes more costly with a higher carbon content. However, the difference between mild steel and hard steel is not just a matter of the distinction between second-class and premium liquor. *For more detailed information, please refer to the PDF.

The relationship between yield point, tensile strength, strength, and hardness in steel tensile testing.

The relationship between yield point, tensile strength, strength, and hardness in steel tensile testing.

[Reprint Private Spring Preparatory School Lecture 27] Explanation of the load and elongation diagram in the tensile test of steel!

Today, let's study a little about the terms that express the strength and brittleness of steel. The strength of steel is usually understood through a tensile test. As you may know, in a tensile test, a tensile load is applied along the axis of the specimen until it fractures, and during this process, the relationship between the load and elongation, as well as the reduction in cross-sectional area, reveals the elastic limit, yield point, tensile strength, elongation, and reduction of area. *For detailed content of the article, you can view it in the PDF.

The relationship between ski downhill courses and the cooling rate of steel quenching.

The relationship between ski downhill courses and the cooling rate of steel quenching.

[Reproduction of Private Spring Preparatory School Lecture 30] Explaining what happens when the cooling speed from high temperatures is changed!

Steel has a stepchild called carbon, and when it is rapidly cooled from a high temperature, it does not undergo a straightforward transformation, but instead becomes a solid solution of carbon in alpha iron. This quenched structure is called martensite. The microscopic structure of martensite is needle-like and very hard. For example, the hardness of martensite in spring steel is about 700 on the Brinell hardness scale. However, not all steels achieve this level of hardness. *For more detailed information, please refer to the PDF. Feel free to contact us for further inquiries.*

Differences in types of spring steel wire and manufacturing processes.

Differences in types of spring steel wire and manufacturing processes.

[Reprint Private Spring Preparatory School Lecture 36] An explanation of the differences between the brothers of spring steel wire and their growth processes!

I taught you how to read JIS standards, but take another look at the spring steel wire. Indeed, thinner wires have greater tensile strength than thicker ones. The thickest one is the 12 mm "spring carbon steel oil-tempered wire," which has a tensile strength of 120 kg. Looking at it this way, we can define spring steel wire as having a diameter of 12 mm or less and a tensile strength of 120 kg or more. Why is strong steel wire used for springs? It is because the cross-sectional shape is uniform and the material length is long, making it convenient to mass-produce springs with consistent characteristics. *For more detailed information, please refer to the PDF.

The purpose and effects of low-temperature annealing of wire springs, and the importance of the manufacturing process.

The purpose and effects of low-temperature annealing of wire springs, and the importance of the manufacturing process.

[Reproduction of Private Spring Preparatory School Lecture 40] Explanation of the changes in mechanical properties due to low-temperature annealing of piano wire and oil-tempered wire!

Today, let's study why this annealing and spring wire undergo low-temperature annealing and what effects it has when low-temperature annealed. Now, let's learn what low-temperature annealing is. In heat treatment terminology, there is no term for low-temperature annealing. It is referred to as low-temperature normalization. This is because there is no character for "anneal" in the commonly used kanji. Low-temperature normalization is a method of annealing that involves heating below the transformation temperature to adjust internal stresses. *For detailed content of the article, you can view it in the PDF.

Principles, Effects, and Practical Methods of Shot Peening and Setting

Principles, Effects, and Practical Methods of Shot Peening and Setting

[Reproduction of Private Spring Preparatory School Lecture 44] Shot peening is a surface treatment! Explanation of the final process setting as well.

Shot peening is a surface treatment. It is very effective for springs made from heat-treated steel wire and springs that are formed from annealed wire and then heat-treated, but it is not as effective for springs made from cold-worked steel wire. This is because the surface of cold-worked steel wire is originally quite smooth. It is said that "a fair complexion hides seven troubles," and indeed, having a fair complexion is the first condition of beauty. Such beauties only need to wash their faces, and there is no need to apply expensive cosmetics. *For detailed content of the article, please refer to the PDF.

Exploring the relationship between fishing and springs: Research for the school festival and the fun of the Japanese language.

Exploring the relationship between fishing and springs: Research for the school festival and the fun of the Japanese language.

[Reproduction of Private Spring Preparatory School Lecture 49] Fishing rods are similar to springs in that they utilize the elasticity of bamboo, that is, the force of rebound!

Today, let's go to the fishing club's classroom. Steel can be broken down into the blade of a tool and metal. With this method, most things can be deconstructed, and their etymology can be traced. For example, the "forge" in blacksmith comes from the "ka" and "chi" of "kaneuchi" (metal hitting). Additionally, the chisel used by blacksmiths is a "cutting metal," and the hatchet used for cutting wood combines the "na" from "Kusanagi no Tsurugi" (the sword of Kusanagi) and the "ta" from "to cut." Now, how are fishing and springs connected using this method? Look forward to the research results from the fishing club. *For detailed content of the article, please refer to the PDF.

The selection and importance of metal materials for springs learned with the arrival of spring.

The selection and importance of metal materials for springs learned with the arrival of spring.

[Reproduction of Private Spring Preparatory School Lecture 50] Studying metal materials for springs! I will explain the types of steel most commonly used for springs.

There are many materials used for springs. For example, the skis that I played with in the winter mountains until recently can be thought of as board-like springs that slide on the snow, and until not long ago, they were made from wood. However, nowadays, they are made from not only wood but also materials ranging from fiberglass to metal. Let's consider why these materials have been chosen. Since skis are also springs, they must not break or deform immediately when a person, who is the load, stands on them; otherwise, they would be unusable. In other words, we want an elasticity that is suitable for the load. *For more detailed information, please refer to the PDF. For inquiries, feel free to contact us.*

The causes of burning defects and the impact of decarburization on the fatigue strength of spring steel.

The causes of burning defects and the impact of decarburization on the fatigue strength of spring steel.

[Reprint Private Spring Preparatory School Lecture 57] Burn marks can occur due to uneven quenching temperatures, uneven cooling, and the presence of scale!

Burning unevenly, that is, the cause of insufficient heating in localized areas, is often due to decarburization. Now, let's study decarburization, which is the main cause of this issue. Decarburization cannot be avoided when heating steel, not just spring steel, to high temperatures. The mechanical properties of steel are proportional to the carbon content, and fatigue strength is well proportional to hardness up to the level of spring hardness. Springs are generally used in a way that bending or torsional stresses are applied, and these stresses act so that the maximum stress occurs on the surface of the spring. *For detailed content of the article, please refer to the PDF.

Effects and countermeasures of crystal grain growth, surface oxidation, and reduction of fatigue strength in spring steel due to overheating.

Effects and countermeasures of crystal grain growth, surface oxidation, and reduction of fatigue strength in spring steel due to overheating.

[Reproduction of Private Spring Preparatory School Lecture 58] As the grain size increases, the resistance to impact decreases, and the fatigue strength also diminishes!

The damage from overheating is not just limited to decarbonization. The grain size also increases, and surface oxidation leads to more severe skin roughness. When the grain size increases, the impact value, which refers to resistance to impact, decreases, and fatigue strength also declines. Speaking of the decline in fatigue strength, surface oxidation significantly affects skin roughness. Here, please take another look at the JIS standards for spring steel materials. *For detailed content of the article, please refer to the PDF. For more information, feel free to contact us.*
