It is nitriding steel that is added Al. Cr. in nitriding treatment to possess superior fatigue strength, surface hardness and wear-resistance, so it can be used to produce high-precision mechanical parts.
Cylinder liner, compressor parts, hydraulic parts,…etc.
SACM645 is a nitrided steel, which is mostly used for high p
MORESACM645 is a nitrided steel, which is mostly used for high precision mechanical parts.
It can achieve high surface hardness, wear resistance and fatigue strength after nitriding heat treatment by adding aluminum (Al) and chromium (Cr) alloy elements to the steel, and is commonly used in cylinder liners, compressor parts and hydraulic parts.
The content of aluminum (Al) ranges from 0.70% to 1.20%.
