Basic information stainless steel: SUS301 characteristics: SUS301 (17Cr-7Ni) stainless steel high strength can be obtained after cold working. SUS301 stainless steel for railway vehicles, conveyor, bolts and nuts, springs, etc. Chemical composition ● Chemical Composition: Carbon C: ≤0.15 silicon Si: ≤1.00 Mn Mn: ≤2.00 sulfur S: ≤0.030 phosphorus P: ≤0.035 chromium Cr: 16.00 ~ 18.00 Ni Ni: 6.00 ~ 8.00 304 properties containing low contrast SUS301 Ni , Cr and high N content, high strength can be achieved by cold working. Ordinary steel SUS301 contrast, have excellent high temperature strength, fatigue strength and corrosion resistance, light weight, use the tram to reach. Features 1) after cold deformation to obtain high strength and hardness; 2) comparing ordinary steel with excellent high temperature strength, fatigue strength and corrosion resistance, light weight and use the tram to reach, reduce costs SUS301 (17Cr-7Ni) by cold After high strength can be obtained. For rail vehicles, conveyor, bolts and nuts, springs, etc. Rusty 301 cases a long time there may rust, but it is impossible to rust within a short period of time. Stainless steel will rust, rusty speed time to see specific environment: moist, acid-base and strong air environment rusted fast, faster than inland beach on rust. Stainless steel itself depends on the material, mainly from rust-proof function is nickel, according to the level of nickel content is divided into several types: from low to high is 201 #, 202 #, 301 #, 304 #. Steel wire Classification (301) stainless steel bright line, (301) stainless steel car axis, (301) stainless steel, electrolytic line, (301) stainless steel cord, (301) stainless steel annealing line, (301) stainless steel hydrogen retreat cord, stainless steel wire, stainless steel wire flattening, (301) polished stainless steel wire, not (301) stainless steel hairpin wire, stainless steel wire semicircular lines. SUS301 density of 7.93g / cm-3. Mechanical properties of tensile strength σb (MPa): ≥520 Conditions yield strength σ0.2 (MPa): ≥205 Elongation δ5 (%): ≥40 section shrinkage ψ (%): ≥60 Hardness: ≤187HB; ≤ 90HRB; ≤200HV heat Heat Specifications: 1010 ~ 1150 ℃ rapid cooling. Microstructure: Organizing for the austenitic type. Delivery status generally heat treatment delivery, the treatment types specified in the contract; not indicated, by not heat treatment delivery.
