What is SUS301 material?

SUS 301 is an austenitic stainless steel with a nominal composition of 17 percent chromium and 7 percent    nickel. The high strengths of this grade of steel in the six available conditions or tempers, its resistance to atmosphere corrosion and its bright, attractive surface make it an excellent choice for decorative structural applications. Automobile molding and trim, wheel covers, conveyor belts, kitchen equipment, roof drainage systems, hose clamps, springs, truck and trailer bodies, railway and subway cars are some of the major applications for this versatile grade. By varying the chemical composition within the limits set by the ASTM specifications and by temper rolling, a broad range of magnetic and mechanical properties can be obtained       for a variety of applications.

Is SS 301 corrosion resistance?

SS301 is resistant to a variety of corrosive media. However, the corrosion properties are not as good as             the 18-8 chromium-nickel steels. Its susceptibility to carbide precipitation during welding restricts its use            in many applications in favor of SUS 304 or SUS 304L.

What’s the difference between 301 and 304 stainless steel?
Generally speaking, grade 301 tends to be a little less corrosion resistant than grade 304 because the 301 alloy has a lower chromium content and a higher level of carbon. At higher temperatures, the difference in corrosion resistance is more pronounced.
