Screw Strengthening Manual (Vol. 41) Sometimes it can be partially hardened!

Screw Strengthening Manual (Vol. 41) Sometimes it can be partially hardened!

Introducing a method to heat only the surface of materials that can be hardened, in a blog format!

This time, I will talk about high-frequency hardening. It is a heat treatment method where a copper wire coil, called a high-frequency coil, is wrapped around a product that you want to harden, and heat is applied by passing an electric current to harden only the surface. While one might think that general heat treatments like quenching or annealing would suffice for hardening, there are valid reasons for choosing high-frequency hardening. *For more detailed content, you can view it through the related links. Please feel free to contact us for more information.*

To suppress distortion and increase surface hardness, nitriding hardening is used.

To suppress distortion and increase surface hardness, nitriding hardening is used.

Compared to carbonization, deformation and dimensional changes are minimal!

- It is possible to achieve a surface hardness of 800 HV or higher even with low carbon steel. - The amount of gas used is about 1/10 of that for gas nitriding. - There is a high resistance to temper softening. - The finish is better compared to carburizing and similar processes. - Corrosion resistance is better than that of carburizing.

[Metal Heat Treatment Guide] What is Quenching?

[Metal Heat Treatment Guide] What is Quenching?

Heat treatment that changes the state of martensitic structure! A method used when forging Japanese swords!

"Quenching" is a heat treatment process that involves heating steel to an austenitic structure and then rapidly cooling it in water or oil, transforming it into a martensitic structure. Depending on the cooling medium, it is referred to as water quenching or oil quenching, and it is also a method used in the forging of Japanese swords. This process is performed to increase the hardness of the steel, but it reduces toughness, so it is common to perform tempering after quenching to achieve ductility. 【What is Quenching】 ■ A process that changes the state of steel from an austenitic structure to a martensitic structure by heating it and then rapidly cooling it in water or oil. ■ A method used in the forging of Japanese swords. ■ The quenching effect cannot be expected unless the carbon content is 0.3% or higher. *For more details, please refer to the PDF document or feel free to contact us.

The composition and structure of spring steel, the changes in strength due to carbon content, and the importance of quenching.

The composition and structure of spring steel, the changes in strength due to carbon content, and the importance of quenching.

[Reproduction of Private Spring Preparatory School Lecture 53] Study of heat treatment that creates spring hardness! Explanation of carbon that strengthens steel.

I plan to study the heat treatment that creates spring hardness. That said, since there are new students, let's also study the structure beforehand. Pure iron is surprisingly soft, so it is not useful in the machinery industry. However, if you add a tiny amount of carbon to this iron, it becomes something very useful called carbon steel. The amount of carbon increases in the order of mild steel, medium carbon steel, hard steel, and ultra-hard steel, with the carbon steel for springs (SUP3 and 4) belonging to the ultra-hard steel category. Even in this ultra-hard steel, the carbon content is only about 1.5%. I apologize for the repetition, but let's take another look at the JIS spring steel material table here. *For detailed content of the article, you can view it in the PDF. For more information, please feel free to contact us.*

[Case Study] Increase Hardness of S55C!

[Case Study] Increase Hardness of S55C!

Proposal for Ensuring Hardness! Introduction of Case Studies on Increasing Hardness by Changing to Heat Treatment "Salt Quenching"

This is a case study that succeeded in extending the lifespan by changing the heat treatment method of S55C to "salt quenching." [Consultation Details] The S55C shaft was being hardened using vacuum oil quenching, but hardness could not be secured. [Solution Case] We proposed changing to salt quenching, which has good heat transfer, and upon performing the quenching, we were able to secure the hardness. Additionally, the salt quenching eliminated uneven hardening and resulted in a fine hardened structure, contributing to the extended lifespan of the product.

This is an introduction to a case where changing the heat treatment of leaf springs to "salt quenching" successfully reduced distortion. 【Consultation Details】 We want to perform quenching on leaf springs that cannot be corrected for distortion, aiming for minimal distortion. 【Solution Case】 We proposed changing the quenching method from oil quenching to the less-distorting "salt quenching." We succeeded in reducing the distortion after quenching.

[Case Study] Reducing Distortion of Long Shafts and Simplifying Subsequent Processes

[Case Study] Reducing Distortion of Long Shafts and Simplifying Subsequent Processes

Proposal example for shortening delivery times! Introduction of a case study on reduced distortion by changing to heat treatment "salt quenching."

This is a case study on successfully reducing distortion and shortening delivery times by changing the heat treatment method for long shafts to "salt quenching (salt bath quenching)." 【Consultation Details】 The long shafts that underwent gas carburizing heat treatment exhibited significant distortion, leading to increased heat treatment delivery times, costs, and post-processing efforts, prompting a need for a solution. 【Solution Case】 A proposal was made to switch to heat treatment and cooling using a salt bath. The characteristics of the salt bath allow for uniform quenching with minimal distortion, resulting in a reduction in the number of polishing finishing processes and consequently shortening the delivery time.
