304 Stainless Steel Coil Introduction
Product Overview
304 Stainless Steel Coil
304 stainless steel coil is one of the most popular steel coils across the globe for a number of its favorable characteristics. 304 stainless steel mainly consists of iron, chromium and nickel. This combination makes for outstanding oxidation resistance and corrosion resistance of 304 stainless steel coils. 304 stainless steel is a versatile stainless steel material with stronger anti-rust properties than 200 series stainless steel materials. It also has better high temperature resistance. The 304 stainless steel coil is featured by a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. Due to its good versatility and relatively low cost, 304 stainless steel coil is commonly used in fields including food processing equipment, building materials, automobile parts.
