50CrVA特性及适用范围: 良好的力学性能和工艺性能,淬透性较高,加入钒使钢的晶粒细化,降低过热敏感性,提高了强度和韧性,具有高的疲劳强度,屈服比也较高,但焊接性差,冷因变形塑性低。是一种较高级弹簧,用作较大截面的高负荷重要弹簧及工作温度<300 ℃的阀门弹簧、活塞弹簧、安全阀弹簧。
50CrVA Properties and Scope of Application: It has good mechanical and process properties, high hardenability. The addition of vanadium refines the steel grain, reduces overheating sensitivity, improves strength and toughness, has high fatigue strength, and a high yield ratio. However, it has poor weldability and low cold forming plasticity. It is a higher-grade spring, used for larger cross-section high-load important springs, valve springs, piston springs, and safety valve springs operating at temperatures below 300 ℃.
