1/2H 3/4H H EH HV :310-370 HV :370-430 HV :430-490 HV :490-530 Features: SUS301 (1Cr17Ni7) stainless steel high strength can be obtained after cold working. SUS301 stainless steel for railway vehicles, conveyor, bolts and nuts, springs and so on. Chemical composition Carbon C: ≤ 0.15 Si Si: ≤ 1.00 Manganese Mn: ≤ 2.00 Sulfur S: ≤ 0.030 Phosphorus P: ≤ 0.035 Chromium Cr: 16.00 ~ 18.00 Ni-Ni: 6.00 ~ 8.00 304 contains a low contrast features SUS301 Ni, Cr, and high N components can achieve high strength by cold working. SUS301 contrast to the common steel, has excellent high temperature strength, fatigue strength and corrosion resistance, the use of the tram up and light weight. Features 1) obtained by cold deformation, high strength and hardness; 2) contrast to the common steel with excellent high temperature strength, fatigue strength and corrosion resistance, the use of the tram achieve light weight, lower cost SUS301 (17Cr-7Ni) by cold obtained after high strength. For rail vehicles, belt conveyors, bolts and nuts, springs and so on. Mechanical Properties Tensile strength σb (MPa): ≥ 520 Conditions yield strength σ0.2 (MPa): ≥ 205 Elongation δ5 (%): ≥ 40 Reduction of area ψ (%): ≥ 60 Hardness: ≤ 187HB; ≤ 90HRB; ≤ 200HV Heat Treatment Heat Treatment Specification: 1010 ~ 1150 ℃ rapid cooling.
