What are the characteristics and roles of quenching, tempering, annealing, and normalizing?

What are the characteristics and roles of quenching, tempering, annealing, and normalizing?

We will introduce the four basic patterns of heat treatment that bring out the properties of iron!

There are four main methods of heat treatment. The toughness we discussed last time is imparted by performing "tempering." It is often said "quenching and tempering," and it is common to perform these together to give steel surface hardness and toughness. Annealing and normalizing are not frequently used in the processing we mainly handle, but the photo of the handle shows that annealing was performed to soften the iron and bend it. The base part of the bend has undergone annealing. *For more detailed information, you can view it through the related links. Please feel free to contact us for more details.*

What are the characteristics and roles of hardening, tempering, annealing, and normalizing?

Introducing four basic patterns of heat treatment that bring out the properties of iron in a blog!

There are four main methods of heat treatment. The toughness I mentioned last time is imparted by performing "tempering." It is often said "quenching and tempering," and it is common to carry out these processes together to give steel surface hardness and toughness. Annealing and normalizing are not frequently used in the processing we mainly handle, but the photo of the handle at the beginning shows that annealing was performed to soften the iron and bend it. The root part of the bend has undergone annealing. Without annealing, it would be hard, and cracks would occur during bending, or it would break. *You can view the detailed content of the blog through the related links.

N Quench (Nitriding Hardening)

N Quench (Nitriding Hardening)

The finishing skin is good! The processing time is short, and a 20μ curing layer can be obtained in 40 minutes.

"N-Quench (Nitriding Quenching)" is a treatment method that allows nitrogen to penetrate and dissolve in steel within the austenite region of the Fe-N phase diagram, followed by rapid cooling to obtain hard nitrogen martensite. In nitriding quenching, the nitrided layer hardens into nitrogen martensite due to rapid cooling, but the interior does not harden because it is cooled from below the transformation temperature of the Fe-C system. Furthermore, the thermal treatment distortion (dimensional change) is comparable to that of gas soft nitriding. 【Features】 ■ Hardness of HV800 or higher can be achieved even with low carbon steel. ■ The amount of gas used is extremely small, about 1/10 of that used in gas soft nitriding. ■ Processing time is short, with a hardened layer of 20μ obtained in 40 minutes. ■ The finish is good. ■ The treatment is environmentally friendly. *For more details, please refer to the PDF document or feel free to contact us.

N-hard (gas soft nitriding hardening)

N-hard (gas soft nitriding hardening)

A 20μ curing layer can be obtained with a 40-minute treatment! This is a processing method that can reduce operating costs.

"N-Hard (Gas Soft Nitriding)" is a treatment method where gas soft nitriding is performed just above the A1 transformation temperature on the Fe-N phase diagram, followed by rapid cooling to obtain a mixed phase of nitrides and nitrogen martensite. The surface forms an extremely hard layer compared to the nitrided layer, consisting of a mixed phase of nitrides (or carbonitrides) and nitrogen martensite. However, the interior undergoes rapid cooling below the A1 transformation of the Fe-C system, so it does not harden. 【Features】 ■ Thermal treatment distortion (dimensional change) is small, comparable to gas soft nitriding. ■ Hardness of HV800 or higher can be achieved even with low carbon steel, and HV1000 or higher with SK5. ■ Processing time is shorter compared to gas soft nitriding, achieving a hardened layer of 50μm in 90 minutes. ■ Processing time is short, achieving a hardened layer of 20μm in 40 minutes. ■ The finish is good. *For more details, please refer to the PDF document or feel free to contact us.

Flame hardening

Flame hardening

Local heating for processing complex shapes. Suitable for small-batch production of various types.

By applying high-temperature flames such as oxy-acetylene flames to locally heat the surface of steel parts, it is less affected by the shape of the workpiece. Skilled craftsmen accurately control the temperature using the color of the flame. Additionally, it is economical because it does not require fixtures or coils like high-frequency heat treatment (quenching) for the same localized heating process. ● It is used for processing complex machined parts that cannot be handled by high-frequency quenching. ● We conduct thorough prior discussions and perform heat treatment suitable for the material. ● It is economical because it does not require the cost of manufacturing special fixtures.

[Processing Technology] Flame Hardening (Frame Hard)

[Processing Technology] Flame Hardening (Frame Hard)

Partial hardening of small parts! It is possible to have a hard surface with high wear resistance and a tough core!

"Flame hardening" is a process that involves heating the surface of steel with a high-temperature flame, followed by quenching to harden the surface layer. Using a torch, the steel is heated partially and then rapidly cooled. This process allows for a hard surface layer with high wear resistance and a tough core, resulting in significant residual compressive stress on the surface, which improves fatigue strength. It is suitable for partial hardening of small items (approximately Φ30 or smaller). 【Features】 ■ A process that heats the surface of steel with a high-temperature flame and then hardens the surface layer. ■ Capable of producing a hard surface layer with high wear resistance and a tough core. ■ The generation of significant residual compressive stress on the surface improves fatigue strength. ■ Suitable for partial hardening of small items (approximately Φ30 or smaller). ■ JIS processing symbol: HQF *For more details, please refer to the PDF document or feel free to contact us.
