Product Details

Description:
51CrV4 (1.8159) spring steel good mechanical properties and process performance, high hardenability, adding vanadium steel grade refinement, reducing heat sensitivity ,increase the strength and toughness, high fatigue strength, yield ratio is higher, but poor weldability, cold because of the low deformation plasticity.
51CrV4 steel equivalent grade:
ASTM JIS DIN GB
6150 SUP10 1.8159 50CrVA
Application:
51CrV4 is a kind of more advanced spring,as a large section of the high load important spring and working temperature <300ºC of the valvespring,piston,spring,the relief valve spring.
