Stainless Steel Flat Bar Flat 304 316 Stainless Steel Flat Steel Building Materials
304 Stainless Steel is an austenite steel and contains between 16% and 24% chromium and up to 35% nickel. The most common type of 304 stainless steel is the 18/8 or 18-8 steel, which constitutes 18% chromium and 8% nickel. Additionally, it contains about 2% manganese, 0.1% nitrogen, 0.03% sulphur, 0.08% carbon, 0.75% silicon and 0.045% phosphorous. 304 stainless steel is the most popular and widely used grade of steel.
