SCM440合金鋼化學(xué)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合金鋼性能:
1。淬火性好,可進(jìn)行深度淬火,而不是市面上防鋸形鎖的表面淬火
2。對(duì)回火脆性傾向少
3。高溫加工性好,加工后美觀
4。熔接性好
5。沖擊的吸收性能好,錘子砸上去會(huì)與反彈感,無(wú)法進(jìn)行暴力破壞
優(yōu)點(diǎn): (1).加工性好 (2).沖擊的吸收性能好 (3).焊接容易
SCM440合金鋼用途:
SCM440是生產(chǎn)高強(qiáng)度緊固件的常用鋼種,產(chǎn)品具有成分穩(wěn)定、有害元素低、鋼質(zhì)純凈度高、脫碳層小,表面缺陷少等優(yōu)點(diǎn),使用時(shí)易進(jìn)行球化退火、冷鐓開(kāi)裂率低,熱處理質(zhì)量穩(wěn)定、硬度均勻,廣泛應(yīng)用在發(fā)動(dòng)機(jī)、模具等行業(yè)。
