SCM415 Alloy steel Annealing

Annealing Temperature 800~850 ℃(1472~1562°F

SCM415 chromoly processed through carburizing hardening treatment, Refer SCM415 Alloy steel Hardening

Carburizing hardening improves wear resistance and fatigue strength by creating a tough, high-carbon surface layer. This treatment also increases the material's ability to withstand surface pressure and ensures a longer lifespan under harsh conditions.

This makes it ideal for use in environments where the material must endure stress or extreme conditions.

X30WCRV93KU Grade have high rigidity, SCM415 Case Harden steel Fatigue Strength

X30WCRV93KU exhibits high rigidity due to its molybdenum and chromium content, which enhances tensile and yield strength. This makes it ideal for pressure vessels and high-pressure applications. When SCM415 is case hardened, the surface becomes harder, improving fatigue resistance. Proper execution of this process is essential to maintain the material’s properties.
