Heat treatment of materials

Heat treatment of materials

Correction using a 300-ton press is also possible! We are introducing the heat treatment of materials.

Heat treatment of materials is conducted in an atmospheric environment. We can perform heat treatment on items weighing up to 10 tons. Typically, we heat treat with a finishing allowance, making it suitable for items such as mold materials and machine parts that require finishing after heat treatment. Correction using a 300-ton press is also possible. There are various types of heat treatment, including quenching and tempering (hardening), normalizing, and annealing. After heating, cooling is done using oil quenching, forced air cooling, or furnace cooling to impart the desired mechanical properties. 【Features】 - Heat treatment of materials is conducted in an atmospheric environment. - Heat treatment can be performed on items weighing up to 10 tons. - Correction using a 300-ton press is also possible. - After heating, cooling is done using oil quenching, forced air cooling, or furnace cooling to impart the desired mechanical properties. *For more details, please refer to the PDF document or feel free to contact us.

Vacuum heat treatment

Vacuum heat treatment

Providing strength to steel while achieving a beautiful silvery finish. Small lot support.

One of the features of our vacuum heat treatment is the ability to handle a wide variety of small lot sizes. By having both large and small furnaces, we achieve short delivery times even for diverse small lots. Since vacuum heat treatment is batch processing, urgent cases may incur additional costs due to the need to reserve the furnace exclusively. However, by utilizing vacuum furnaces of different sizes, we have established a system that can meet detailed heat treatment requests. ● Both our headquarters factory (in Yamato City, Kanagawa Prefecture) and our Tohoku office (in Kitakami City, Iwate Prefecture) have vacuum heat treatment furnaces. ● We primarily focus on vacuum quenching and tempering, but we also offer other processes such as solution treatment, magnetic treatment, precipitation hardening, aging treatment, and vacuum carburizing quenching. ● At our factory, we mainly handle small to medium-sized items weighing from a few dozen grams to about 100 kg, and through our heat treatment network, we can accept a wide range of products. ● While we primarily work with steel, we also have many years of experience in heat treatment of stainless steel. We also accept test heat treatments for new materials.

Silicon alloy laser solid solution heat treatment

Silicon alloy laser solid solution heat treatment

Building a new process design! Conducting evaluation tests using the mobile solidification method and high-speed rotation solidification method.

We will introduce the laser heat treatment tests for "Silicoloy." Laser heat treatment technology can minimize thermal effects on the base material compared to high-frequency heat treatment, allowing for localized hardening or softening. By combining the heat treatment characteristics of the precipitation-hardened Silicoloy with laser heat treatment (localized solid solution heat treatment), we aim to establish a new process design. This time, we conducted evaluation tests using the moving solid solution method and high-speed rotating solid solution method. For details of the tests, please download the catalog. 【Moving Solid Solution Test Conditions】 ■ Laser Oscillator: LDF4000 ■ Beam Shape: 11mm x 6mm ■ Absorber: Present ■ Moving Speed: 20cm/min ■ Upper Limit Output: 1000W-1200W *For more details, please refer to the PDF materials or feel free to contact us.

Why make only the surface hard?

Why make only the surface hard?

I will introduce heat treatment for hardening surfaces in a blog format!

There are two types of heat treatment applied to screws: overall heat treatment and surface heat treatment. I will talk about surface heat treatment, which literally hardens the surface. Surface heat treatment can be broadly divided into two methods: one is to heat elements that lead to hardening, such as carburizing and quenching, allowing them to permeate from the surface, and the other is to heat only the surface of materials that can be hardened, such as high-frequency quenching. *For more details, you can view the related links on the blog. Please feel free to contact us for more information.

Surface hardening heat treatment "Carburizing quenching / Carburizing nitriding quenching"

Surface hardening heat treatment "Carburizing quenching / Carburizing nitriding quenching"

Improving wear resistance and fatigue resistance by diffusing and infiltrating carbon.

"Carburizing hardening" is a surface hardening heat treatment that involves introducing carbon into the surface of steel in a heated gas carburizing furnace, increasing the carbon concentration near the surface, and then performing quenching and tempering. Additionally, "carburizing nitriding hardening" is a treatment that enhances hardenability by adding a small amount of ammonia during the carburizing process to introduce nitrogen. 【Characteristics】 ■ Carburizing hardening and tempering - Improved surface pressure strength, wear resistance, and fatigue strength - Toughness is maintained ■ Carburizing nitriding hardening and tempering - Allows for lower temperature treatment compared to general carburizing hardening - Enables hardening of low carbon steels due to nitrogen (N) diffusion - Uniformity of surface hardness and hardened layer - Bright treatment is possible *For more details, please download the PDF 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 Performance 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 parts or materials, which changes their characteristics. Why is heat treatment necessary? Metallic materials have the property of being brittle the harder they are. 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.*

Understanding Heat Treatment: Metal Materials and Heat Treatment

Understanding Heat Treatment: Metal Materials and Heat Treatment

Metal materials used for various applications! Among them, there are also various products that require heat treatment!

I would like to introduce "Metal Materials and Heat Treatment." Steel materials used in metal processing can be broadly divided into "ordinary steel" and "special steel." "Ordinary steel" is a type of steel that is widely used. It is found in products across all fields, including civil engineering, construction, and machinery, and is mainly used as auxiliary components. "Special steel" is classified into three main categories: structural steel, tool steel, and other special-purpose steels. *For more details, please refer to the PDF document or feel free to contact us.*
