弹簧钢概述（泓鑫）弹簧在冲击、振动或长期交应力下使用，所以要求弹簧钢有高的抗拉强度、弹性极限高的疲劳强度。在工艺上要求弹簧钢有一定的淬透性、不易脱碳、表面质量好等碳素弹簧钢即含碳量WC在0.6%-0.9%范围内的优质碳素结构钢。合金弹簧钢主要是硅锰系钢种，它们的含碳量稍低，主要靠增加硅含量Wsi提高性能；另外还有硌、钨、钒的合金弹簧钢。近年来，结合我国资源，并根据汽车、拖拉机设计新技术的要求，研制出在硅锰钢基础上加入硼、铌、钼等元素的新钢种，延长了弹簧的使用寿命，提高了弹簧质量！主要弹簧钢有：泓鑫日本弹簧钢：SUP6SUP7SUP9SUP9ASUP10SUP11ASUP12SUP13SUJ2SUJ3SUJ4SUJ5SUP10-CSPSK55-CSPSK85-CSPS70C-CSPS65C-CSPS60C-CSPS55C-CSPS50C-CSP泓鑫韩国弹簧钢：SPS1SPS3SPS4SPS5SPS5ASPS6SPS7SPS8SPS9STB1STB2STB3STB4STB5SH590PSH590S泓鑫瑞典弹簧钢：1770177417781912191419221926194019571973泓鑫英国弹簧钢：38Si745SiCrV6-246Si746SiCrMo650SiCrMo651CrV452CrMoV452SiCrNi554SiCr654SiCrV655Cr356Si756SiCr760Cr360CrMo3-160CrMo3-260CrMo3-360SiCrV761SiCr7251A85251A60251H60525A58525A60525H60525A61658A57658A57704A60705A60705H60735A51735H51735A54805H60925A60251A85251A60251H60525A58N525A60535A99805A20832H13泓鑫德国弹簧钢：C67SCK67C75SCK75C85SCK85C100SCK10138Si638Si746Si751Si756Si755Si71.12311.12481.12691.12741.50221.50231.50241.50251.50231.50281.5029151421.52251.71021.71031.71061.70181.1381.7161.77011.77371.81591.816158CrV450CrV451CrV445CrMoV6-751CrMoV452CrMoV455Cr352MnCrB360SiCr761SiCr756SiCr767SiCr554SiCr651MnV760SiMn571Si765Si7泓鑫美国弹簧钢：ASTMA228ASTMA227ASTMA679ASTMA229ASTMA231ASTMA232ASTMA878ASTMA401AISI302ASTMA313AISI316ASTMA313AISI63A-286Inconel718InoconelX-750AMS5698AMS5699AISI1050ASTMA682AISI1074AISI1095AMS6455AISI9254AISI301AISI302AISI316AISI631ASTMA693A-286AMS5525Inconle600ASTMB168AMS5540Inconel718AMS5596AMS5597InconelX-750AMS5542泓鑫中国弹簧钢:657075808565Mn55Si2Mn55Si2MnB55SiMnVB60Si2Mn60Si2MnA60Si2CrA60Si2CrVA60CrMnA50CrMn55CrMnA50CrVA60CrMnBA60CrMnMoA30W4Cr2VA泓鑫国际标准弹簧钢：38Si746Si751CrV452CrMoV455Cr355SiCr6-355SiCrV6-356SiCr760Cr360CrMo3-360Si861SiCr7)
