：退火,285～229HB,壓痕直徑3.6～4.0mm;淬火,≥57HRC6CrW2Si鋼熱處理規(guī)范及金相組織熱處理規(guī)范：試樣淬火860～900℃,油冷。6CrW2Si鋼交貨狀態(tài)鋼材以退火狀態(tài)交貨。參考對應牌號中國GB 標準牌號6CrW2Si、俄羅斯r0cT 標準牌號6xB2C、 法國NF 標準牌號55wc20、德國DlN 標準牌號60WCrv7、德國DIN 標準材料編號1. 2550、瑞典SIS 標準牌號2550、國際標準化組織(ISO) 標準牌號60WCrV2。典型應用舉例①適用于用碳工鋼制造而承載能力不足、用油淬火的低變形鋼及Cr12系鋼制造，易于脆裂，而用高速鋼或高強度鋼制造，又不經(jīng)濟的高耐磨的模具。②當模具以磨損和堆塌為主要失效形式時，可改用此鋼。③適用于制造剪刀、切片沖頭等。④可用于重負荷下工作的沖模、壓模、鑄造精整工具、風動鑿子等。⑤作為熱加工用鋼，可生產(chǎn)螺釘和熱鉚的沖頭。⑥高溫壓鑄輕合金的頂頭。⑦熱鍛模等。
