What are Stainless Steel 304 ERW Pipes?

Stainless Steel 304 ERW Pipes are manufactured by rolling stainless steel strips into a tubular shape and joining the edges through an electric resistance welding process. The ERW manufacturing method produces a strong and uniform weld seam while maintaining the excellent properties of Stainless Steel 304.

Grade 304 stainless steel contains approximately 18% chromium and 8% nickel, providing outstanding resistance to oxidation, corrosion, and chemical attack. These pipes are suitable for both indoor and outdoor applications where durability and hygiene are essential.
