Wuxi 304 stainless steel 304 stainless steel chemical grade old 06Cr19Ni10 grades (0Cr18Ni9) containing 19% chromium, and nickel-containing 8-10%. 304 stainless steel is the most widely used stainless steel, heat resistant steel. For food production equipment, common chemical equipment, nuclear energy. 304 stainless steel chemical composition C Si Mn PS Cr Ni (nickel) Mo, chemical composition (SUS304) ≤ 0.08 ≤ 1.00 ≤ 2.00 ≤ 0.05 ≤ 0.03 18.00 to 20.00 8.00 ~ 10.50 for 304 stainless steel is a very important parameter, directly determine its corrosion resistance, and to determine its value. The 304 most important element is Ni, Cr, but it is not limited to these two elements. The specific requirements of product standard requirements. The industry common judgment situation think that as long as the Ni content of more than 8% Cr content greater than 18%, that is 304 stainless steel. This is why the industry will kind of stainless steel called 18/8 stainless steel. In fact, the product standard 304 has very clear provisions of these product standards for different shapes of stainless steel, there are some differences. Here are some common product standards and testing. http://www.wybxg.com/
