Product Introduction

51CrV4 SPRING STEEL BAR has good mechanical properties and process properties, high hardenability, adding vanadium to refine the grain of steel, reduce overheating sensitivity, improve strength and toughness, with high fatigue strength, yield ratio is also high, but poor weldability, cold deformation plasticity is low.

Is a higher level spring, used as a large cross-section of high load important spring and operating temperature. 300 ℃ valve spring, piston spring, safety valve spring.
