ASTM A312 seamless stainless steel pipe (304/316) from TPMC is manufactured by piercing solid billets, involving no welding at any stage. This ensures a uniform structure with exceptional strength and reliability.
As austenitic stainless steel, it offers excellent formability, non‑magnetic properties, and superior corrosion resistance. Suitable for high‑temperature and general corrosive service, it is widely used in petroleum, chemical, marine, automotive, and mechanical structural applications.
