Spring steel
Steel belongs to alloy spring steel, which is the German standard steel number, corresponding to China.
Characteristics and scope of application:
(.) Spring steel has good mechanical properties and process properties, and high hardenability. Adding vanadium refines the grains of the steel, reduces overheating sensitivity, and improves strength. It has high fatigue strength and high yield ratio, but has poor weldability and low plasticity due to cold deformation. It is a higher-grade spring, used as a large cross-section high-load important spring and a valve spring, piston spring, and safety valve spring with an operating temperature of ℃.
