Stainless Steel 304H Pipes

Stainless Steel 304H Pipes refer to a specific type of stainless steel pipe made from the alloy 304H. Stainless steel is a corrosion-resistant iron-based alloy with a minimum of 10.5% chromium. The addition of chromium enhances the corrosion resistance of stainless steel by forming a thin, protective oxide layer on the surface. The "304" in Stainless Steel 304H refers to the grade of stainless steel, and the "H" stands for high carbon content. The 304H variant is an austenitic stainless steel, which means it belongs to the group of iron-chromium-nickel alloys known for their excellent corrosion resistance, high strength, and good formability.
