Description

Built for strength, precision, and reliability, the 31.7 mm 304L Stainless Steel Round Bar is the perfect choice for projects that demand exceptional corrosion resistance, easy weldability, and long-term durability. Crafted from low-carbon 304L stainless steel, this solid bar minimizes the risk of carbide precipitation during welding, ensuring cleaner, stronger joints without compromising structural integrity.

The smooth, precision-machined finish makes it ideal for accurate fabrication, while its high chromium and nickel content provide outstanding protection against rust, oxidation, and everyday wear — even in moist or mildly corrosive environments.

Whether you’re a fabricator, machinist, or builder, this weld-ready stainless steel bar offers the versatility you need for industrial, commercial, and DIY applications.
