304 Stainless Steel Bar Description
304 stainless steel bar is one of the most popular stainless steel bars across the globe for a number of reasons. Iron, chromium and nickel are the main elements that constitute 304 stainless steel. This combination gives rise to the outstanding oxidation resistance and corrosion resistance of 304 stainless steel bars. 304 stainless steel has stronger anti-rust properties than 200 series stainless steel materials as a versatile stainless steel. It also outperforms them in temperature resistance. The 304 stainless steel bar has characteristics of a smooth surface, high plasticity, toughness and mechanical strength, as well as resistance to corrosion by acids, alkaline gases, solutions and other media. 304 stainless steel bars are commonly used as manufacturing parts in fields like food processing equipment, building materials, automobile parts.
