304 stainless steel pipe is the most common type of steel pipe across the globe for a number of its characteristics. 304 stainless steel is primarily composed of iron, chromium and nickel. This combination gives rise to outstanding oxidation resistance and corrosion resistance. 304 stainless steel is a versatile stainless steel material with better anti-rust properties than 200 series stainless steel materials. It also outperforms them in high temperature resistance. 304 stainless steel pipe features a smooth surface, high plasticity, toughness and mechanical strength, and is very resistant to corrosion by acids, alkaline gases, solutions and other media. 304 stainless steel pipes are widely used in food processing equipment, building materials, automobile parts and other fields for its versatility and relatively low cost.
