Stainless Steel Welded Pipe – Type 304L

Stainless Steel Welded Pipe – Type 304L offers seamless and welded construction with cold drawn, annealed, and pickled finish. Available in 20′ random lengths. Suitable for various industrial applications. Grades: ASTM A312, A269. Common applications include food processing, chemical processing, pharmaceutical, and petrochemical industries.

Steel Welded Pipe – Type 304L is a versatile and widely used material for various industries due to its excellent corrosion resistance, durability, and formability. Its low carbon content and chromium-nickel austenitic stainless steel alloy composition provide a high level of resistance to corrosion in oxidizing and reducing environments, making it suitable for harsh environments. The addition of nickel enhances its corrosion resistance and formability.
