Stainless steel: SUS301 features: SUS301 (17Cr-7Ni) stainless steel obtained by cold working after high intensity. SUS301 stainless steel for railway vehicles, belt, bolts and nuts, springs, etc. Edit this paragraph the chemical composition 
 ● Chemical Composition: 
 SUS301 Stainless Steel 
 Carbon C: ≤ 0.15 Si Si: ≤ 1.00 Manganese Mn: ≤ 2.00 S S: ≤ 0.030 P P: ≤ 0.035 Cr-Cr: 16.00 ~ 18.00 Ni-Ni: 6.00 ~ 8.00 editing feature of this paragraph 
 SUS301 containing low-contrast 304 Ni, Cr and high-N component, can be achieved through the cold high 
 SUS301 
 Strength. SUS301 contrast to ordinary steel, have excellent high temperature strength, fatigue strength and corrosion resistance, light weight and use the tram to reach. Features 1) obtained after cold deformation of high strength and hardness; 2) compared ordinary steel, has excellent high temperature strength, fatigue strength and corrosion resistance, light weight and use the tram to reach, reduce costs SUS301 (17Cr-7Ni) by cold available after high intensity. For rail vehicles, belt, bolts and nuts, springs, etc. Edit this paragraph rust 
 301 a long time may rust, but not within a short period of time rusted. Stainless steel will rust, rusty time to see the speed of the specific environment: humidity, pH and strong rust faster in the air environment, the sea than inland rust faster. Stainless steel depends on the material itself, the main function of the rust from the nickel, according to the level of nickel content is divided into several types: from low to high is 201 #, 202 #, 301 #, 304 #. Edit this paragraph classification of steel wire 
 (301) stainless steel bright line, (301) stainless steel car axis, (301) stainless steel electrolytic line, (301) stainless steel full cord, (301) stainless steel annealing line, (301) stainless steel hydrogen withdrawal cord, stainless steel square, stainless steel squash line, (301) stainless steel polishing line, not (301) stainless steel hairpin line, semicircular line of stainless steel such as stainless steel wire. SUS301 density 7.93g/cm-3.
