冷镦性能是冷镦钢的重要性能之一。冷镦钢应具备的主要性能是，具有良好的冷成形性；对于冷镦钢变形要具有尽可能小的阻力和可能高的变形能力。为此，一般要求冷镦钢的屈强比为0.5~0.65，断面收缩率大于50%。此外，为避免在冷镦时表面开裂，要求钢材表面质量良好，同时钢材的表面脱碳要尽可能小。冷拉钢：A3 Q195 Q215 Q235 Q345A/B/C/D/E/F Q275 Q295 Q390A/B/C/D/E Q420A/B/C/D/E Q460C/D/E 1006 1008 1010 1012 1020 1025 1030 1035 1040 1045 1050 1055 S10C S15C S20C S25C S30C S35C S40C S45C S50C S55C S58C 45# 10# 20# 30# 40# 35# 25# 55# 冷镦钢 ML04Al ML08Al ML10Al ML15Al ML15 ML20Al ML20 ML18Mn ML22Mn ML20Cr ML25 ML30 ML35 ML40 ML45 ML15Mn ML25Mn ML30Mn ML35Mn ML37Cr ML40Cr ML30CrMo ML35CrMo ML42CrMo ML20B ML28B ML35B ML15MnB ML20MnB ML35MnB ML37CrB ML20MnTiB ML15MnVB ML20MnVB SWRCH6R SWRCH8R SWRCH10R SWRCH12R SWRCH15R SWRCH17R SWRCH6A SWRCH8WA SWRCH10A SWRCH12A SWRCH15A SWRCH16A SWRCH18A SWRCH19A SWRCH20A SWRCH22A SWRCH25A SWRCH10K SWRCH12K SWRCH15K SWRCH16K SWRCH17K SWRCH18K SWRCH20K SWRCH22K SWRCH24K SWRCH25K SWRCH27K SWRCH30K SWRCH33K SWRCH35K SWRCH38K SWRCH40K SWRCH41K SWRCH43K SWRCH45K SWRCH48K SWRCH50K SWRCH6R SWRCH8R SWRCH10R C2C C4C C8C C10C C15C C17C C20C 8MnSi7 C10E2C C15E2C C17E2C C20E2C 10NiCr5-4 12CrMo4 12NiCr3-2 15B2 16MnCr5 16MnCrB5 16MnCrS5 17Cr3 17CrNi6-6 17CrS3 18B2 18CrMo4 18CrMoS4 18MnB4 20MnCrS5 20MnCr4 20MnCrS4 20NiCrMo2-2 20NiCrMoS6-4 22MnB4 C35EC C35RC C45EC C45RC 25CrMo4 25CrMoS4 34Cr4 34CrMo4 34CrNiMo6 37Cr4 37CrMo4 37Mo2 38Cr2 41Cr4 41CrS4 41NiCrMo7-3-2 42CrMo4 42CrMoS4 46Cr2 17B2 17MnB4 20MnB4 23B2 23MnB4 27MnB4 22B2 30MnB4 30MoB1 31CrMoB2-1 32CrB4 33B2 36CrB4 36MnB4 37MnB5 38B2
