Low-temperature nitriding and low-temperature carburizing
01 What is Low Temperature Nitriding?
Low temperature nitriding is a surface hardening treatment of austenitic stainless steel surface hardening treatment by solid solution of nitrogen in austenitic stainless steel The hardened layer has a metallic structure called S-phase (expanded austenite), and the surface is hardened while maintaining the corrosion resistance and non-magnetic properties of the material compared to high-temperature nitriding. Compared to high-temperature nitriding, there is less distortion.
02 Surface cross-sectional microstructure
Treatment conditions: 430°C x 5 hours
03 Features of Low Temperature Nitriding
- 1) Abrasion and friction resistance
- 2) Corrosion resistance/corrosion protection
- 3) Non-magnetic (no change)
- 4) Good finished surface
- 5) High hardness (800HV, 10~15μm )
04 What is Low Temperature Carburization?
Low-temperature carburizing is a surface hardening treatment of austenitic stainless steels surface hardening treatment of austenitic stainless steel by solid solution of carbon. and produces a metallic structure called S-phase (expanded austenite) in the hardened layer, hardening the surface while maintaining corrosion resistance and non-magnetic properties compared to high-temperature carburizing. Less distortion compared to high-temperature carburizing.
