Atmosphere-Controlled Furnace Heat Treatment

This process relies on a special gas atmosphere to cover and protect the metal during the process of improving its quality and properties.

The heat treatment processes we provide using an atmosphere-controlled furnace are:

1. Carburizing Process (HCQT)

• Suitable for: Low Carbon Low Alloy Steels, such as SCM415, SCM420, and SCR420.
• This process involves introducing carbon elements to the surface of the workpiece to increase its hardness after the subsequent quenching process.

2.Carbonitriding Process (HCNQT)

• Suitable for: Common (plain) Steels, such as SS400, SPHC, and JSC270.
• This process involves introducing carbon and is supplemented by nitrogen elements to the surface of the workpiece. This improves the hardenability of these common steel grades.

2. Quenching & Tempering (HQT)

• Suitable for: Medium Carbon Steels (Carbon content: 0.3% and above).

• This is a full-body hardening process for the workpiece. The resulting part will have increased hardness extending from the surface right through to the core of the material.
