供应日本SCr440,SCr450合金结构钢板，钢棒，钢带，圆钢

合金结构钢：SCr440 　　 　　●特性及适用范围： 　　是常用的合金结构钢，抗拉强度、屈服强度及淬透性均比40号钢高，但焊接性有限，有形成裂纹的倾向。用于较重要的调质零件，如交变负荷下工作的零件、中等转速和中等负荷的零件。表面淬火后可作负荷和及耐磨性较高、而无很大冲击的零件，如齿轮、套筒、轴、曲轴、销子。 本公司供应各国合金结构钢：国产：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 美国：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 德国：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，欢迎来电咨询!
