Stainless steel round tube 304
Detail

STAINLESS STEEL WELDED ROUND TUBE


PRODUCT       FEATURES

Welded 304 Stainless Steel round tube/  tubing is less costly than seamless or welded-and-drawntubing, and requires less stock removal in machining applications. It can alsobe produced with extremely thin walls. 304 stainless steel is the mostversatile and widely used of stainless steel grades, due to its combination ofcorrosion resistance, formability, and ductility.
