SCM440合金钢化学成份:
C 0.38-0.42
Si 0.15-0.35
Mn 0.60-0.85
P ≤0.03
S ≤0.03
Cu ≤0.30
Ni ≤0.25
Cr 0.90-1.20
MO 0.15-0.30
SCM440合金钢性能:
1。淬火性好,可进行深度淬火,而不是市面上防锯形锁的表面淬火
2。对回火脆性倾向少
3。高温加工性好,加工后美观
4。熔接性好
5。冲击的吸收性能好,锤子砸上去会与反弹感,无法进行暴力破坏
优点: (1).加工性好 (2).冲击的吸收性能好 (3).焊接容易
SCM440合金钢用途:
SCM440是生产高强度紧固件的常用钢种,产品具有成分稳定、有害元素低、钢质纯净度高、脱碳层小,表面缺陷少等优点,使用时易进行球化退火、冷镦开裂率低,热处理质量稳定、硬度均匀,广泛应用在发动机、模具等行业。
