SNCM220圓棒
SNCM220
(滲碳)軸承鋼:SNCM220
執(zhí)行標準: JIS G4053-2003
特性及適用范圍:
SNCM220軸承鋼是一種常用的合金滲碳鋼,滲碳處理后表面有相當高的硬度、耐磨性和接觸疲勞強度,同時心部還保留良好的韌性,能承受高的沖擊負荷。SNCM220主要用作汽車軸承等耐沖擊、耐磨損零件的材料。

抗拉強度 σb (MPa):≥1176(120)
伸長率 δ5 (%):≥9
斷面收縮率 ψ (%):≥45
沖擊韌性值 αkv (J/cm2):≥78(8)
試樣尺寸:試樣尺寸為15mm
熱處理規(guī)范及金相組織:
熱處理規(guī)范:淬火,第一次880±20℃,第二次790±20℃,油冷;回火,150~200℃,空冷。
金相組織:馬氏體。
交貨狀態(tài):熱軋或鍛制鋼材以熱軋(鍛)狀態(tài)或退火狀態(tài)交貨。冷拉鋼材以退火狀態(tài)交貨。
