The Low-Carbon Stainless Steel Pipe is specifically designed for welding applications where resistance to intergranular corrosion is critical. With a maximum carbon content of 0.03% (compared to 0.08% in standard grades), this pipe minimizes the formation of chromium carbides during welding, preventing sensitization and preserving corrosion resistance in the heat-affected zone (HAZ). Manufactured as seamless or welded and subsequently annealed, it offers excellent weldability, consistent mechanical properties, and long-term reliability in corrosive service.

Comparison – Standard grades (304 / 316): C ≤ 0.08%. Low carbon (L) grades significantly reduce carbide precipitation risk.

Tested in accordance with ASTM E8 / E8M.
