Welded 304 Stainless Steel tubing is less costly than seamless or welded-and-drawn tubing, and requires less stock removal in machining applications. It can also be produced with extremely thin walls. 304 stainless steel is the most versatile and widely used of stainless steel grades, due to its combination of corrosion resistance, formability, and ductility. Welded 316 Stainless Steel tubing features a weld bead on the inside diameter. It is less expensive than seamless or welded-and-drawn tubing. 316 stainless steel provides the best resistance to pitting and corrosion of any of the austenitic (300 series) stainless steels. It is extremely ductile, with excellent strength at elevated temperatures.
