詳細(xì)信息:
軸承鋼 GCr9SiMn 標(biāo)準(zhǔn):GB/T 1299-1985
●特性及適用范圍:
量具刃具用鋼,此鋼成分與 GCr9SiMn軸承鋼相當(dāng),其淬透性、硬度和耐磨性都較碳素工具鋼高,熱處理時尺寸變化也不大。廣泛用作量具,如樣板、卡板、樣套、量規(guī)、塊規(guī)、環(huán)規(guī)、螺紋塞規(guī)和樣柱等,也可用于制造拉絲模和冷鐓模等冷作模具,以及低速刀具切削不太硬的材料。
●化學(xué)成份:
碳 C :0.95~1.10
硅 Si:≤0.40
錳 Mn:≤0.40
硫 S :≤0.030
磷 P :≤0.030
鉻 Cr:1.30~1.65
鎳 Ni:允許殘余含量≤0.25
銅 Cu:允許殘余含量≤0.30
●力學(xué)性能:
硬度 :退火,229~179HB,壓痕直徑4.0~4.5mm;淬火,≥62HRC
●熱處理規(guī)范及金相組織:
熱處理規(guī)范:試樣淬火830~860℃,油冷。
●交貨狀態(tài):鋼材以退火狀態(tài)交貨。
