Metal heat treatment (from small to large items, from single pieces to mass production)

Metal heat treatment such as stress relief annealing.

Metals are diverse and each has different characteristics, requiring different appropriate heat treatment methods (such as temperature and time) for each material. Additionally, when some processing is applied to the metal (the processed material), factors like processing heat can cause the metal structure to become unbalanced, leading to internal stress that accumulates, known as residual stress. As a countermeasure, heat treatments such as "stress relief annealing" are used to uniform the stress distribution. The question of "how to reduce residual stress" greatly influences the precision of the product. Issues such as lack of precision during machining or deterioration of precision due to aging distortions can often be resolved through a planned heat treatment process. Our company, well-versed in metal heat treatment, responds to various customer demands.

Technical Introduction: "Carburizing Heat Treatment"

Technical Introduction: "Carburizing Heat Treatment"

Establishing a more accurate processing technology using our own software!

Carburizing heat treatment technology is a thermal process that involves the infiltration of carbon into the surface of steel, followed by quenching. By introducing carbon, it significantly improves the wear resistance, durability, and toughness of steel components. Historically, carburizing techniques included solid and liquid carburizing, but currently, gas carburizing is the mainstream method. Additionally, advanced techniques such as vacuum carburizing and plasma carburizing have been developed and continue to evolve. The significant improvements in wear resistance, durability, and toughness of steel components have led to their use in various applications, including automotive parts, machine tool components, and construction machinery parts, such as gears, shafts, and moving parts, thereby supporting industrial development and enhancing material heat treatment technology. ● For more details, please contact us.

Screw Reinforcement Book (Vol. 34) What happens when screws are heat treated?

Screw Reinforcement Book (Vol. 34) What happens when screws are heat treated?

Introducing changes in properties due to heat treatment and types of heat treatment in a blog format!

Through heat treatment, the properties of steel mainly change in four ways: "the steel becomes harder," "the steel becomes tougher," "the structure of the steel becomes uniform," and "the steel becomes softer." Additionally, there are two main types of heat treatment applied to screws. "Overall heat treatment" is a process that changes the properties of the entire steel, making it stronger, harder, or conversely, softer. "Surface heat treatment" is a process that changes the properties only of the surface of the steel, primarily hardening the surface.

Continuous heat treatment "Austempering"

Continuous heat treatment "Austempering"

Imparting spring properties to thin plates! Improved ductility, impact resistance, toughness, and durability.

"Aus-tempering treatment" is a continuous heat treatment that imparts strong spring performance to high carbon steel (C: 0.6% or more) thin plate products (t: up to 2.0mm). After heating in a non-oxidizing atmosphere furnace to the austenite region (approximately 800°C to 900°C), it is held isothermally in the lower temperature range (approximately 300°C to 450°C) below the S-curve nose, and then cooled, which imparts a bainitic structure to the product. Due to extremely low thermal distortion and dimensional changes, as well as the attainment of good spring performance, it is widely used for thin plate springs and similar applications. [Characteristics] ■ Tough toughness and impact resistance ■ Reduction of thermal distortion and dimensional changes *For more details, please download the PDF or feel free to contact us.

Understanding Heat Treatment: Types of Heat Treatment

Understanding Heat Treatment: Types of Heat Treatment

There are basically 4 patterns! The heat treatment method varies depending on the purpose of the product and the characteristics of the materials.

I would like to introduce the "types of heat treatment." The basics of heat treatment consist of four patterns: "quenching," "tempering," "normalizing," and "annealing." Each method adjusts the metal structure through heating and cooling to achieve the desired properties. There are also various methods with different names. 【Types of Heat Treatment】 ■ Normalizing, Annealing ■ Quenching, Tempering, Sub-zero (deep cooling treatment) ■ Stress Relief ■ Solution Treatment/Precipitation Hardening ■ Carburizing, Nitriding *For more details, please refer to the PDF document or feel free to contact us.

Introduction to Heat Treatment: A Beginner's Guide from the Basics

Introduction to Heat Treatment: A Beginner's Guide from the Basics

[Functional and Property Improvement] Basic Knowledge of Heat Treatment Used in Automotive Parts and Aircraft Parts

Heat treatment refers to a metal processing technique aimed at improving the properties of metallic materials. The heat treatment process involves heating, holding, and cooling components or materials, which changes their characteristics. Why is heat treatment necessary? Metallic materials have the property of being brittle as they become harder. They are strong against deformation, but when a certain amount of force is applied, they can suddenly break or crack. It is common to apply heat treatment to improve the properties of metallic materials. We are currently offering a beginner's booklet that provides basic knowledge about heat treatment as a gift. *For more details, please refer to the PDF document or feel free to contact us.*

Processing technology High-speed salt bath heat treatment

Processing technology High-speed salt bath heat treatment

The heating retention period can be individually set, and salt bath quenching prevents quenching distortion and cracking.

Iwata Tool conducts salt bath heat treatment services for both its own products and external products as a tool manufacturer. Utilizing the know-how of high-speed tools, we confidently carry out the treatment. Salt bath heat treatment has many advantages that vacuum heat treatment does not offer. Particularly for tools requiring toughness, such as drills and punches, there is currently nothing superior to salt bath heat treatment. Additionally, because salt bath heat treatment is processed sequentially rather than in batches, appropriate treatment is applied regardless of the size of the lot. As a result, we can flexibly accommodate small lots. Furthermore, the cooling capacity of the salt bath is very rapid, allowing for heat treatment of large items that is impossible with other heat treatment methods. A uniform heating state is achieved, resulting in stable quenching hardness. After heat treatment, all products undergo long hours of washing, pickling, and rust prevention neutralization. Additionally, upon request, we also perform shot blasting with glass beads and apply rust prevention oil. For more details, please contact us or refer to our catalog.
