50Crv4
50Crv4 spring steel, spot + 50 crv4 plank long-term supply, fast delivery, good quality and good mechanical properties and process performance, high hardenability, adding vanadium steel grain 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. Is a kind of more advanced spring, as a large section of important spring high load and working temperature < 300 ℃ of the valve spring, piston, spring, the relief valve spring. Final heat treatment for hardening and tempering steel, the steel after heat treatment has good toughness, high limit and ultimate strength, high fatigue strength, and is similar to 65 si2mnwa hardenability, high hardenability and low overheating sensitivity; Parts temperature at 300 ℃, its elastic still can maintain. Steel machinability is good, but when the cold deformation plasticity is low, poor weldability
