Carburizing hardening, carburizing nitriding hardening, bright hardening

Carburizing hardening, carburizing nitriding hardening, bright hardening

An easy-to-understand introduction to carburizing hardening, carburizing nitriding hardening, and bright hardening!

This is an introduction to carburizing quenching conducted by Asahi Heat Treatment Co., Ltd. When carbon steel and low alloy steel are quenched, the hardness obtained is primarily determined by the carbon content, with little influence from the added alloying elements. The higher the carbon content, the greater the quenching hardness; however, if it exceeds 0.85%, the amount of residual austenite during quenching may increase, making it difficult to achieve hardness. Carburizing quenching is applied to low carbon steel materials. For example, even if low carbon steel is quenched, the hardness obtained is around HRC20, but by diffusing carbon from the surface and increasing the surface carbon concentration, hardness of over HRC60 can be achieved. In addition, we also introduce carburizing nitriding quenching and bright quenching. [Features] - Quenching hardness is determined mainly by the carbon content. - The higher the carbon content, the greater the quenching hardness. - Carburizing quenching is applied to low carbon steel materials. - Carbon is diffused using low carbon steel materials. - A method to create materials that are hard on the surface, softer internally, and have toughness. *For more details, please refer to the PDF document or feel free to contact us.

[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.

Surface hardening heat treatment method "Nitriding Quenching"

Surface hardening heat treatment method "Nitriding Quenching"

Heat treatment technology that finishes thin materials firmly without distortion! Capable of short delivery times.

This is a new surface hardening heat treatment method that allows nitrogen to infiltrate and diffuse into steel, followed by quenching from the austenite state. By allowing nitrogen to infiltrate and then quenching, a surface hardness of about 850 HV can be achieved even with inexpensive SPCC materials, and it is possible to increase hardness within the range where nitrogen has diffused. The amount of distortion is about half that of carburizing nitriding quenching and only slightly larger than gas soft nitriding. The friction coefficient and seizure surface pressure are almost equivalent to those of carburizing nitriding quenching and gas soft nitriding, while the wear amount is favorable at half that of carburizing nitriding materials and one-third that of gas soft nitriding materials. 【Features】 - The surface roughness of the samples after treatment is good. - The time required for treatment can be significantly reduced to about one-third to one-fourth of that for gas soft nitriding. - It has a tempering softening resistance comparable to that of carburizing. - The amount of distortion is about half that of carburizing nitriding. - Superiority in friction and wear characteristics has been demonstrated. *For more details, please refer to the catalog or feel free to contact us.

"Partial high-strength steel material" high-frequency hardening

"Partial high-strength steel material" high-frequency hardening

This is a steel material that achieves multiple strengths with a single bar of steel. High-frequency quenching allows for only the areas that require high strength and high durability to be treated with high strength.

In conventional heat treatment using furnaces, it was difficult to apply heat to only the necessary parts of the steel material, as heat was applied to the entire steel. However, by utilizing high-frequency induction heating (IH) to selectively high-frequency quench only a portion of the steel (enhancing strength and durability), multiple strengths have been achieved with a single steel rod. By placing high-strength sections in areas where the integrity of structures and components must be ensured, and low-strength sections in other areas, damage control and reduction of materials are possible. Using this technology and product, we have started selling high-strength rebar placed in column and beam joints that contribute to damage control of structures, reduction of rebar quantity, improved workability, and comfortable living spaces, named "Double Stark®." *In 2018, we received the "Super" Monozukuri Parts Award and the Lifestyle-Related Parts Award.

[Processing Technology] Vacuum Carburizing (Direct Carburizing)

[Processing Technology] Vacuum Carburizing (Direct Carburizing)

Since there are no grain boundary oxidation or carburization irregularities on the surface layer, it is also possible for the inner surface of the pores! Quality improvement can be expected.

"Vacuum carburizing hardening" is a carburizing hardening method conducted in a vacuum furnace. Acetylene gas supplied into the furnace undergoes thermal decomposition, and the carbon generated penetrates and diffuses from the surface. In addition to the carburizing effect, there is no grain boundary oxidation or carburizing unevenness in the surface layer, making it possible for the inner surfaces of pores as well. Moreover, since it finishes with a bright luster, quality improvement can be expected compared to conventional carburizing hardening. 【Features】 ■ Carburizing hardening method conducted in a vacuum furnace ■ In addition to the carburizing effect, it allows for the inner surfaces of pores due to the absence of grain boundary oxidation and carburizing unevenness in the surface layer ■ Finishes with a bright luster ■ Quality improvement can be expected compared to conventional carburizing hardening ■ JIS processing symbol: HQV *For more details, please refer to the PDF materials or feel free to contact us.
