    304 Stainless Steel Pipe Description

    304 stainless steel pipe is widely recognized as the most common type of steel pipe globally, owing to its numerous advantageous characteristics. Comprised primarily of iron, chromium, and nickel, this composition results in exceptional oxidation and corrosion resistance. 304 stainless steel is a versatile material with superior anti-rust properties compared to 200 series stainless steel, and it also exhibits enhanced high-temperature resistance. The pipe features a smooth surface, high plasticity, toughness, and mechanical strength, and demonstrates remarkable resistance to corrosion by acids, alkaline gases, solutions, and other media. Due to its versatility and relatively low cost, 304 stainless steel pipes find extensive use in food processing equipment, building materials, automobile parts, and various other fields.
