Technical Introduction: "Carburizing and Nitriding Heat Treatment"

Technical Introduction: "Carburizing and Nitriding Heat Treatment"

We have a wealth of accumulated technology in the field of processing techniques for reducing material costs, which is one of our strengths.

Carburizing and nitriding treatment refers to the process of simultaneously or continuously performing carburizing and nitriding. Generally, for materials with poor hardenability, such as low-carbon low-alloy steel, carburizing is conducted while adding ammonia gas or similar substances to achieve both carburizing and nitriding, aiming to improve the hardenability of the material at lower transformation temperatures. By performing nitriding, it becomes possible to effectively introduce hardness into materials that do not harden with carburizing alone. The quality characteristics obtained from carburizing and nitriding treatment include improved wear resistance and fatigue strength, similar to carburizing, as well as enhanced softening resistance. Recently, carburizing and nitriding treatment has also been applied to alloy steel or bearing steel for the purpose of improving mechanical properties. ● For more details, please contact us.

Technical Introduction: "Radiant Heat Treatment"

Technical Introduction: "Radiant Heat Treatment"

We carry out shine treatment for a variety of products, from large items to small goods!

Bright annealing refers to a state where the product shines brightly, as the name suggests. The atmosphere of the heat treatment furnace is adjusted to process the products without causing surface oxidation. Our company uses nitrogen gas and a mixture of nitrogen and hydrogen gas to prevent oxidation on the product surface. We manage the atmosphere from the time the products are loaded into the heat treatment furnace until the heating and cooling processes are complete. We have a pit-type bright annealing setup, allowing us to perform bright annealing on a variety of products, from large items to small parts. The main processing contents are as follows: - Magnetic annealing treatment of low carbon steel - Microstructure adjustment of skin-hardened steel (for stabilizing grain size after carburizing) - Oxidation-free stress relief annealing Additionally, we have water cooling equipment, enabling us to perform heating without oxidation and cooling with water. - Water cooling treatment for copper alloys - Water cooling treatment for titanium alloys For more details, please contact us.

Technical Introduction: "Heat Treatment of Large Products"

Technical Introduction: "Heat Treatment of Large Products"

We have multiple facilities capable of handling large components, and we possess a top-class equipment system in the country.

Large components are designed to withstand greater forces compared to small components. Therefore, the required carburizing depth in heat treatment is also deeper. Additionally, as the components themselves become larger, the time taken for heating, cooling, and tempering, aside from processing time, increases. Our company enables a reduction in carburizing time by performing high-temperature, high-concentration carburizing. We have extensive experience in carburizing large components and possess technical know-how. We have multiple facilities capable of processing large components, and we have a top-class equipment system in Japan. In terms of processing capacity, we can handle outer diameters of up to 2200 mm and lengths of up to 6000 mm. We receive many orders not only domestically but also from overseas, and our high processing technology is widely recognized. ● For more details, please 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.*

[Metal Heat Treatment Guide] What is Annealing?

[Metal Heat Treatment Guide] What is Annealing?

Introducing "tempering," which increases strength and ductility and is also used as a preliminary treatment for quenching.

"Annealing" is a heat treatment that removes internal stresses caused by processing, restores the structure to a standard state, and refines it. By performing annealing, strength and ductility are increased, making it useful as a preliminary treatment for quenching. Additionally, steel is held in the austenite structure for a sufficient period and then cooled adequately in air. 【What is Annealing】 ■ Removes internal stresses caused by processing ■ Restores the structure to a standard state or refines it ■ Steel is held in the austenite structure for a sufficient period and then adequately cooled in air *For more details, please refer to the PDF document or feel free to contact us.

Electric heating elements for industrial furnaces, used in metal heat treatment, electronic components, and chemical industry applications!

Electric heating elements for industrial furnaces, used in metal heat treatment, electronic components, and chemical industry applications!

Manufacturing heaters suitable for electric furnaces with an internal temperature of up to 1200℃!

A metal heating element refers to a type of resistance heating element among general heating sources. Electric heating elements for industrial furnaces that include this metal heating element are used in various industries such as metal heat treatment, electronic components, ceramics, and chemical industries. Our company manufactures electric furnace heaters suitable for furnace temperatures up to 1200°C using iron-chromium-aluminum alloy (FeCrAl), which is a type of metal heating element. The shapes of metal heating elements vary. Here, we introduce some of the products we handle. 1. Round wire coil heating element This is a heating element made by spirally winding round wire. The wire diameter and outer coil diameter are set according to the heater's capacity and temperature. 2. Strip heating element A zigzag-shaped circuit is formed by alternately slitting plate-like material. By adjusting the slit width, the resistance value of the heating element is changed, allowing for precise design of heater output. Additionally, we perform concave processing calculated to suppress deformation due to thermal expansion of the heating element. This technology has been developed uniquely by our company.

[Technical Introduction] Heat Treatment

[Technical Introduction] Heat Treatment

Introducing three types of "heat treatment": gas carburizing and nitriding, gas soft nitriding, and quenching and tempering!

We would like to introduce the technology related to "heat treatment" held by Kyoritsu Seisakusho. In "gas carburizing and nitriding," we use a carburizing gas RX with 5% to 10% ammonia added. The treatment temperature is between 750°C and 900°C, and the treatment time is shorter than that of gas carburizing, allowing for the formation of a thin hardened layer. Additionally, we possess technologies such as "gas soft nitriding" to improve wear resistance and fatigue resistance, as well as "quenching and tempering." 【Features of Gas Carburizing and Nitriding】 ■ Uses carburizing gas RX with 5% to 10% ammonia added ■ Treatment temperature is between 750°C and 900°C, with a shorter treatment time than gas carburizing ■ Achieves a thin hardened layer ■ Hardening depth ranges from 0.1mm to 0.8mm ■ The carbonitriding layer improves hardenability *For more details, please refer to the related links or feel free to contact us.
