There are three types of wear-resistant chains
1. Low temperature tempering (LTT) G90
Use a temperature lower than A1 during tempering, sacrifice elongation to increase breaking load and hardness (40~42HRC or 390HB), Elongation 14%
2. Quenching only (QO) G60
Only quenching (temperature exceeds AC3) without tempering, sacrifice elongation and breaking load to increase overall hardness (45~47HRC or 450HB), Elongation 10%
3. Carbonitriding (C-N) G40
Through carbonitriding, a hard shell is formed on the surface of the chain (depth: up to 15% of the chain diameter, hardness: up to 64HRC or 800HV), and the core is soft with a certain elongation (relative elongation 1~3.5%).
