304L Stainless Steel Pipe – Corrosion Resistant, Weldable & Versatile | KCM

The 304L Stainless Steel Pipe from KCM is a low-carbon variant of 304 stainless steel, specifically developed to improve weldability and reduce the risk of carbide precipitation during welding. With its exceptional corrosion resistance, excellent formability, and superior mechanical properties, 304L is one of the most widely used stainless steel grades in a range of industries.

This pipe is ideal for food processing, chemical transport, water supply systems, pharmaceutical equipment, and general structural applications. Its low carbon content (<0.03%) makes it non-hardenable by heat treatment, yet highly resistant to intergranular corrosion, especially after welding.

Available in seamless and welded configurations, the 304L pipe by KCM is precision-engineered to international specifications, delivering long-term durability and consistent dimensional accuracy in all operational conditions.
