弹簧钢带弹簧钢板进口日本S55C­—CPS弹簧钢S55C­—CPS弹簧钢特性高质中碳钢。该钢是由电炉、平炉或纯氧转炉炼钢法制造的全静钢，具有加工性优良、金相***均匀的特点。该钢价格便宜，加工容易，适合于高频淬火、火焰淬火等表面硬化处理。该钢含碳量（质量分数，%）≥0.4，耐磨性优良，但延展性减少，淬火易变形和开裂，故淬火极为重要，且回火后必须急冷，以避免发生回火脆性。该钢切削困难，需进行球化处理改善切削性能，原则上回火到硬度19~22HRC，以利于机械加工。供货状态及硬度149~192HBS，183~255HBS，229~285HBS。化学成分（质量分数，%）C0.52~0.58、Si0.15~0.35、Mn0.60~0.90、P≤0.030、S≤0.035、Cu≤0.30、Ni≤0.20、Cr≤0.20.参考对应钢号美国AISI标准钢号1050/1055、日本JIS标准钢号S50C/S55C、德国DIN标准材料编号1.1730。物理性能拉伸强度735MPa，屈服强度372MPa，伸长率δ522%，收缩率38%，冲击韧性值35J/cm2，抗压强度350MPa。荣创***代理美国芬可乐弹簧钢，日本住友弹簧钢，德国进口弹簧钢等等牌号如下：日本弹簧钢：SUP6SUP7SUP9SUP9ASUP10SUP11ASUP12SUP13SUJ2SUJ3SUJ4SUJ5SUP10-CSPSK55-CSPSK85-CSPS70C-CSPS65C-CSPS60C-CSPS55C-CSPS50C-CSP韩国弹簧钢：SPS1SPS3SPS4SPS5SPS5ASPS6SPS7SPS8SPS9STB1STB2STB3STB4STB5SH590PSH590S瑞典弹簧钢：1770177417781912191419221926194019571973英国弹簧钢：38Si745SiCrV6-246Si746SiCrMo650SiCrMo651CrV452CrMoV452SiCrNi554SiCr654SiCrV655Cr356Si756SiCr760Cr360CrMo3-160CrMo3-260CrMo3-360SiCrV761SiCr7251A85251A60251H60525A58525A60525H60525A61658A57658A57704A60705A60705H60735A51735H51735A54805H60925A60251A85251A60251H60525A58N525A60535A99805A20832H13德国弹簧钢：C67SCK67C75SCK75C85SCK85C100SCK10138Si638Si746Si751Si756Si755Si71.12311.12481.12691.12741.50221.50231.50241.50251.50231.50281.5029151421.52251.71021.71031.71061.7018国际标准弹簧钢：38Si746Si751CrV452CrMoV455Cr355SiCr6-355SiCrV6-356SiCr760Cr360CrMo3-360Si8美国弹簧钢：ASTMA228ASTMA227ASTMA679ASTMA229ASTMA231ASTMA232ASTMA878ASTMA401AISI302ASTMA313AISI316ASTMA313AISI631A-286Inconel718InoconelX-750AMS5698AMS5699AISI1050ASTMA682AISI1074中国弹簧钢：657075808565Mn55Si2Mn55Si2MnB55SiMnVB60Si2Mn60Si2MnA60Si2CrA60Si2CrVA60CrMnA50CrMn55CrMnA50CrVA60CrMnBA60CrMnMoA30W4Cr2V弹簧钢带弹簧钢板进口日本S55C­—CPS弹簧钢)
