sus420j2不锈钢

 

SUS420J2 经热处理(淬火回火)后,具有优良的耐腐蚀性能抛光性能较高的强度和耐磨性,适宜制造承受高负荷,高耐磨及在腐蚀介质作用下的塑料模具。

 

简介:

标准:GB/T 1220-1992

属马氏体类型不锈钢,该钢机械加工性能好

经热处理(淬火回火)后,具有优良的耐腐蚀性能抛光性能较高的强度和耐磨性,适宜制造承受高负荷,高耐磨及在腐蚀介质作用下的塑料模具。

调质处理后硬度在HRC30以下的3Cr13材料加工性较好,易达到较好的表面质量。

而硬度大于HRC30时加工出的零件,表面质量虽然较好,但刀具易磨损。

所以,在材料进厂后,先进行调质处理硬度达到HRC25~30,然后再进行切削加工。

旧标准:GB/T 1220-1992 SUS420J2

新标准:GB/T 1220-2007 SUS420J2

比SUS420J2淬火后的硬度高,作刃具、喷嘴、阀座、阀门等。

SUS420J2密度为7.75g/cm3

 

化学成份:

C 0.26-0.40 Mn≤1.00 Si≤1.00,P≤0.040 S≤0.030 Cr 12.00-14.00 Ni≤0.60
