彈簧在沖擊、振動或長期交應力下使用,所以要求彈簧鋼有高的抗拉強度、彈性極限、高的疲勞強度。在工藝上要求彈簧鋼有一定的淬透性、不易脫碳、表面質量好等 碳素彈簧鋼即含碳量WC在0.6%-0.9%范圍內的優質碳素結構鋼。合金彈簧鋼主要是矽錳系鋼種,它們的含碳量稍低,主要靠增加矽含量Wsi提高性能;另外還有硌、鎢、釩的合金彈簧鋼。近年來,結合我國資源,並根據汽車、拖拉機設計新技術的要求,研制出在矽錳鋼基礎上加入硼、鈮、鉬等元素的新鋼種,延長瞭彈簧的使用壽命,提高瞭彈簧質量。 彈簧鋼: 65 70 85 65Mn 55SiMnVB 60Si2Mn 60Si2MnA 60Si2CrA 60Si2CrVA 55SiCrA 55CrMnA 60CrMnA 50CrVA 60CrMnBA 30W4Cr2VA U20652 U20702 U20852 U21653 A77552 A11602 A11603 A21603 A28603 A21553 A22553 A22603 A23503 A22613 A27303 C42 36NiCrMo16 40Si7 45Cr4 45SiCrMo6 45SiCrV646Si750SICrMo6 51CrMoV4 51CrV4 51Si7 52SiCrNi5 54SiCr6 54SiCrV6 55Cr3 56Si756SiCr7 56SiCrV7 60Cr3 60CrMo3 36NCD16 45C4 45SCD6 46S7 50SCD6 51CDV4 51CV4 51S7 55C3 56SC7 60CrMo4 60NiCrMo2 60Si7 60SiCr3 60SiCrV7 61SiCr7 60S7 61SC7 C67S CK67 C75S CK75 C85S CK85 C100S CK101 38Si6 38Si7 46Si7 51Si7 56Si7 55Si7 1.1231 1.1248 1.1269 1.1274 1.5022 1.5023 1.5024 1.5025 1.5026 65Si7 71Si7 60SiMn5 51MnV7 54SiCr6 67SiCr5 56SiCr7 61SiCr7 06SiCr7 52MnCrB3 55Cr3 52CrMoV4 51CrMoV4 45CrMov6-7 51CrV4 50CV4 58CrV4 1.5028 1.5029 1.5142 1.5225 1.7102 1.7103 1.7106 1.7108 1.7138 1.7176 1.7701 1.7737 1.8159 1.8161 38Si7 46Si7 51CrV4 52CrMoV4 52CrMoV4 55Cr3 55SiCr6-3 55SiCrV6-3 56SiCr7 60Cr3 60CrMo3-3 60Si8 61SiCr7 SUP6 SUP7 SUP9 SUP9A SUP10 SUP11A SUP12 SUP13 S50C-CSP S55C-CSP S60C-CSP S65C-CSP S70C-CSP SK85-CSP SK55-CSP SUJ2 SUJ3 SUJ4 SUJ5 SM400A SM400B SM400C SM490A SM490C SM490YA SM490YA SM490YB SM520YB SM520YC SM570 SM41A SM41B SM41C SM50A SM50B SM50C SM50YA SM50YB SM53B SM53C SM58 SPS1 SPS3 SPS4 SPS5 SPS5A SPS6 SPS7 SPS8 SPS9 STB1 STB2 STB3 STB4 STB5 1770 1774 1778 1912 1914 1922 1926 1940 1957 1973 SS1770 SS1774 SS1778 SS1912 SS1914 SS1922 SS1926 SS1940 SS1957 SS1973 38Si7 45SiCrV6-2 46Si7 46SiCrMo6 50SiCrMo6 51CrV4 52CrMoV4 52SiCrNi5 54SiCr6 54SiCrV6 55Cr3 56Si7 56SiCr7 60Cr3 60CrMo3-1 60CrMo3-2 60CrMo3-3 60SiCrV7 61SiCr7 251S85 251S60 251H60 525A58 525A60 525H60 525A61 685A57 685A57 704A60 705A60 705H60 735A51 735H51 735A54 805H60 925A60 251A85 251A60 251H60 525A58 525A60 45A 48 47 44 42 43 43E ASTM A228 ASTM A227 ASTM A679 ASTM A229 ASTM A230 ASTMA231 ASTMA232 ASTM A878 ASTM A877 ASTM A401 AISI 302 AISIA313 AISI316 ASTMA313 AISI631 ASTMA313 A-286 QQ-W390 inconel 600 inconel718 InconelZ-750 AMD5698 AMD5609 AISI1050 ASTM1074 ASTMA682 ASTM A682 AISI 1095 ASTMA682 AMS 6455F AISI 9254 AMS 6451A AISI 302 AISI 301 AISI 316 AISI 631 AISI A693 A-286 AMS 5525 Inconel 600 ASTM B168 AMS5540 Inconel718 AMS 5596 Inconel 600 ASTM B168 AMS5540 AMS5597 InconelX-750 AMS 5542 SUP3 SUP6 SUP7 SUP9 SUP9A SUP10A SUP11A SUP12 SUP13
