Detailed information:
Brand: Spring steel 50CrV4
Characteristics and Scope of Application:
Good mechanical and processing properties, high hardenability, addition of vanadium refines the grain size of steel, reduces overheating sensitivity, improves strength and toughness, has high fatigue strength, and high yield ratio, but poor weldability and low cold deformation plasticity. It is a type of spring used for high load important springs with larger cross-sections and valve springs, piston springs, and safety valve springs with working temperatures<300 ℃
