309S 310S SS Channel
309S stainless steel channel steel is made of stainless steel 309S as the raw material for the channel steel, 309S stainless steel is austenitic chromium-nickel stainless steel, but also in the 309 stainless steel on the basis of the proportion of carbon content to reduce the derivative of the steel, its corrosion and heat resistance than 304 (06Cr19Ni10) stainless steel is good; can withstand the following repeated heating at 980 degrees Celsius, with a high high-temperature strength and oxidation resistance The high chromium content, low nickel content, can be used in the atmosphere with the largest amount of sulfur, heat-resistant temperature of 1000 degrees.
310S ss unistrut channel is made of 310S stainless steel as the raw material of the channel beam, 310S stainless steel is austenitic chromium-nickel stainless steel has very good resistance to oxidation, corrosion resistance, because of the higher percentage of chromium and nickel, so that has a much better creep strength, and can be sustained at high temperatures to continue to work.
