鋼代號 M42. 是美國牌號的超硬鈷高速工具鋼, M42鋼中釩的質量分數不高 (1%), 鈷的質量分數高 (8%), 鈷能促使碳化物在淬火加熱時更多地溶解在基體內, 利用高的基體硬度提高耐磨性。該鋼的硬度、熱硬性、耐磨柱及磨削性都很好。熱處理硬度可達 67~70HRC, 但也有采取特殊熱處理方法, 得到硬度 67 ~68HRC,使其切削性能 (特別是間斷切削) 得到改善, 提高沖擊韌度。該鋼可制成各種刀具,切削難加工材料時效果很好, 又因其磨削性能好. 可制成復雜刀具, 但中國鈷資源缺乏, 鈷高速鋼價格昂貴, 約為普通高速鋼的5~8倍。國產鈷高速鋼在淬回火硬度、熱硬性、使用性能等方面都有了一定的提高, 接近或達到了進口鋼材水平。淬火、回火后硬度≥67HRC, 均勻度≤±0.5%。產品規(guī)格: φ10~150mm, 熱軋、鍛制圓鋼、矩形材、方鋼、鍛件等。按 GB/T 9943-2008 標準或用戶要求組織生產。超硬速鋼是為了適應加工難切削材料, 如耐熱合金等的需要, 在綜合高碳高釩高速鋼與高碳高鈷高速鋼優(yōu)點的基礎上發(fā)展起來的。一般在使用時硬度≥64HRC。該鋼的工藝性能優(yōu)于 M2Al鋼, 冷熱加工性能較好; 淬、回火后硬度與 M35 鋼相同, 為 (66±1)HRC。M42粉末高速鋼,組織更加細化，性能更加優(yōu)異，價格相對更高。 [1]用途特性播報編輯用途適用于制造各種強力切割用耐磨、耐沖擊工具。高級沖模，螺絲模，較需韌性及形狀復雜的沖頭等。刀具業(yè):刮刀,滾齒刀,鐵刀,鉆頭等。鍛造業(yè):鍛造模具。螺絲業(yè):六角等打頭成型模具,牙攻,沖頭 。特性高紅熱硬度,高耐磨耗性與切削能力,高沖擊韌性.晶粒細致均勻,韌性高。碳化物顆粒細、硬度高，耐磨性好熱處理播報編輯等溫退火火:溫度800~880℃，以10~20℃，dHr爐冷至約600℃，硬度在HB269以上。預熱溫度：730-845℃淬火溫度：1190-1210℃回火溫度：540-595℃冷拉態(tài)，硬度285HBS，冷拉后退火態(tài)，硬度277HBS淬火方式：油淬、空冷或鹽浴淬火化學成分播報編輯CSiMnPSCrVWMoCO1.00~1.15≤0.65≤0.40≤0.030≤0.0303.50~4.500.95~1.351.15~1.859.0~10.07.50~8.50相關資料播報編輯高速鋼一般不做抗拉強度檢驗，而以金相、硬度檢驗為主。鎢系和鉬系高速鋼經正確的熱處理后，洛氏硬度能達到63以上，鈷系高速鋼在65以上。鋼材的酸浸低倍組織不得有肉眼可見的縮孔 、翻皮。中心疏松，一般疏松應小于1級。金相檢驗的內容主要包括脫碳層、顯微組織和碳化物不均勻度3個項目。高速鋼不應有明顯的脫碳。顯微組織不得有魚骨狀共晶萊氏體存在。高速鋼中碳化物不均勻度對質量影響最大，目前冶金和機械部門對碳化物不均勻度的級別 十分重視。根據鋼的不同用途可對碳化物不均勻度提出不同的級別要求，通常情況下應小于3級。用高速鋼制造切削工具，除因其具有高硬度、高耐磨性和足夠的韌性之外，還有一個重要因素是具有紅硬性。紅硬性是指刀具在高速切削時，刀刃在紅熱狀態(tài)下抵抗軟化的能力。一種衡量紅硬性的方法是先把鋼加熱至580～650℃，保溫1小時,然后冷卻,這樣反復4次后測量其硬度值。 高速鋼的淬火溫度一般均接近鋼的熔點，如鎢系高速鋼為1210～1240℃，高鉬系高速鋼為1180～1210℃。淬火后一般需在 540～560℃之間回火3次。提高淬火溫度可以增加鋼的紅硬性。為了提高高速鋼刀具的使用壽命，可對其表面進行強化處理，如低溫氰化、氮化、硫氮共滲等。供貨狀態(tài)播報編輯退火態(tài)硬度≤269HBW, 冷拉態(tài)硬度≤285HBW, 冷拉后退火態(tài)硬度≤277HBW。對應牌號播報編輯美國AISI標準牌號 M42、中國 GB 標準牌號 W2Mo9Cr4VCo8、日本JIS標準牌號SKH55、日本日立(HITACHI)標準牌號YXM42、日本不二越(NACHI)標準牌號HSD42、德國 DIN 標準牌號 S2-10-1-8、德國 DIN 標準材料編號 1.3247、奧地利百祿(BOHLER)標準牌號

鋼代號 M42. 是美國牌號的超硬鈷高速工具鋼, M42鋼中釩的質量分數不高 (1%), 鈷的質量分數高 (8%), 鈷能促使碳化物在淬火加熱時更多地溶解在基體內, 利用高的基體硬度提高耐磨性。該鋼的硬度、熱硬性、耐磨柱及磨削性都很好。熱處理硬度可達 67~70HRC, 但也有采取特殊熱處理方法, 得到硬度 67 ~68HRC,使其切削性能 (特別是間斷切削) 得到改善, 提高沖擊韌度。該鋼可制成各種刀具,切削難加工材料時效果很好, 又因其磨削性能好. 可制成復雜刀具, 但中國鈷資源缺乏, 鈷高速鋼價格昂貴, 約為普通高速鋼的5~8倍。國產鈷高速鋼在淬回火硬度、熱硬性、使用性能等方面都有了一定的提高, 接近或達到了進口鋼材水平。淬火、回火后硬度≥67HRC, 均勻度≤±0.5%。產品規(guī)格: φ10~150mm, 熱軋、鍛制圓鋼、矩形材、方鋼、鍛件等。按 GB/T 9943-2008 標準或用戶要求組織生產。超硬速鋼是為了適應加工難切削材料, 如耐熱合金等的需要, 在綜合高碳高釩高速鋼與高碳高鈷高速鋼優(yōu)點的基礎上發(fā)展起來的。一般在使用時硬度≥64HRC。該鋼的工藝性能優(yōu)于 M2Al鋼, 冷熱加工性能較好; 淬、回火后硬度與 M35 鋼相同, 為 (66±1)HRC。M42粉末高速鋼,組織更加細化，性能更加優(yōu)異，價格相對更高。用途特性用途適用于制造各種強力切割用耐磨、耐沖擊工具。高級沖模，螺絲模，較需韌性及形狀復雜的沖頭等。刀具業(yè):刮刀,滾齒刀,鐵刀,鉆頭等。鍛造業(yè):鍛造模具。螺絲業(yè):六角等打頭成型模具,牙攻,沖頭

相關資料高速鋼一般不做抗拉強度檢驗，而以金相、硬度檢驗為主。鎢系和鉬系高速鋼經正確的熱處理后，洛氏硬度能達到63以上，鈷系高速鋼在65以上。鋼材的酸浸低倍組織不得有肉眼可見的縮孔 、翻皮。中心疏松，一般疏松應小于1級。金相檢驗的內容主要包括脫碳層、顯微組織和碳化物不均勻度3個項目。高速鋼不應有明顯的脫碳。顯微組織不得有魚骨狀共晶萊氏體存在。高速鋼中碳化物不均勻度對質量影響最大，目前冶金和機械部門對碳化物不均勻度的級別 十分重視。根據鋼的不同用途可對碳化物不均勻度提出不同的級別要求，通常情況下應小于3級。用高速鋼制造切削工具，除因其具有高硬度、高耐磨性和足夠的韌性之外，還有一個重要因素是具有紅硬性。紅硬性是指刀具在高速切削時，刀刃在紅熱狀態(tài)下抵抗軟化的能力。一種衡量紅硬性的方法是先把鋼加熱至580～650℃，保溫1小時,然后冷卻,這樣反復4次后測量其硬度值。 高速鋼的淬火溫度一般均接近鋼的熔點，如鎢系高速鋼為1210～1240℃，高鉬系高速鋼為1180～1210℃。淬火后一般需在 540～560℃之間回火3次。提高淬火溫度可以增加鋼的紅硬性。為了提高高速鋼刀具的使用壽命，可對其表面進行強化處理，如低溫氰化、氮化、硫氮共滲等。供貨狀態(tài)退火態(tài)硬度≤269HBW, 冷拉態(tài)硬度≤285HBW,
