合金結(jié)構(gòu)鋼：SCr440 　　 　　●特性及適用范圍： 　　是常用的合金結(jié)構(gòu)鋼，抗拉強(qiáng)度、屈服強(qiáng)度及淬透性均比40號(hào)鋼高，但焊接性有限，有形成裂紋的傾向。用于較重要的調(diào)質(zhì)零件，如交變負(fù)荷下工作的零件、中等轉(zhuǎn)速和中等負(fù)荷的零件。表面淬火后可作負(fù)荷和及耐磨性較高、而無(wú)很大沖擊的零件，如齒輪、套筒、軸、曲軸、銷(xiāo)子。 本公司供應(yīng)各國(guó)合金結(jié)構(gòu)鋼：國(guó)產(chǎn)：12Mn,18Nb,10MnSiCu,12MnV,14MnNb,16Mn,15MnV,15MnTi,16MnNb,20Mn2 30Mn2,35Mn2,40Mn2,45Mn2,50Mn2,20MnV,27SiMn,35SiMn,42SiMn,40B, 45B,50B,40MnB,45MnB,20Mn2B,20MnMoB,15MnVB,20MnVB,40MnVB, 20MnTiB,20SiMnVB,15Cr,15CrA,20Cr,30Cr,35Cr,40Cr, 45Cr,50Cr,38CrSi,12CrMo,15CrMo,20CrMo,30CrMo,30CrMoA,35CrMo, 42CrMo,12CrMoV,35CrMoV,12Cr1MoV,38CrMoAl,20CrV,40CrV,50CrVA, 15CrMo,20CrMn,40CrMn,20CrMnSi,25CrMnSi,Q345,Q295,Q390,Q420 美國(guó)：1320, 1330 ,1325, 1340, 1345, 14B35, 14B50, 5115 ,5120, 5130, 5135, 5140, 5145, 5150, 4119, 4118, 4135 4140 ,6140, 6150, 5115, 5120, 4119, 4142, 3140, 3415, 3310, 3435 ,2515 ,3316, 8620 ,4340,E3310,E3316,4347 德國(guó)：20Mn6 ,30Mn5, 36Mn5 ,46Mn7, 50Mn7, 15MnV5, 20MnV6 ,42MnV7 ,37MnSi5, 46MnSi4, 15Cr3, 20Cr4 28Cr4, 34Cr4 ,41Cr4, 13CrMo4.4 ，15CrMo5，20CrMo5，25CrMo4，34CrMo4 ，42CrMo4， 24CrMoV5.5 21CrVMoW12,41CrAlMo7, 21CrV4, 51CrV4, 50CrV4, 16MnCr5, 20MnCr5, 42CrMo4, 30MnCrTi4, 40NiCr6 14NiCr10 ,14NiCr14 ,31NiCr14, 14NiCr18, 21NiCrMo2, 36CrNiMo4, 1.1169 ,1.1165, 1.1167, 1.0912 ,1.0913 1.5213, 1.5217, 1.5223 ,1.5122 ,1.5121, 1.7015, 1.7027, 1.7030, 1.7035, 1.7335, 1.7262, 1.7264, 1.7218 ,1.7220 1.7225, 1.7733, 1.8509, 1.7510, 1.8159, 1.7131, 1.7225, 1.8401 ,1.5711, 1.5732 ,1.5752, 1.5755, 1.5860, 日本：SMn420,SMn433,SMn438,SMn443,SCr415,SCr420,SCr430,SCr435, SCr440,SCr450,SCM415,SCM420,SCM435,SCM440,SCM430,SACM645,SMnC420,SMnC443,SNC236,SNC415,SNC815,SNC631,SNC836,SNCM220,SNCM439, SNCM447 如有需要，歡迎來(lái)電咨詢!
