ASTM A312 TP304 Stainless Steel Seamless Pipe SS

A312 Tp304 tube is pushed or pulled to form a shape usually formed from a round billet of raw material. It is more corrosion resistant than ordinary 304 stainless steel pipe. Our 304 stainless steel seamless tube has a low carbon content, making it highly weldable and formable. Stainless steel 304 welded pipe can be in different shapes such as SS 304 round pipe or SS 304 square pipe. SS 304 Erw tube is used for long service chemical and industrial applications. There are different schedules such as the SS 304 Sch 40 pipeline. Our products are of high quality and have very competitive prices in the market.
