ASTM A312 TP304 Stainless Steel Seamless Pipe with Annealed & Pickled Finish SCH40 in 6 Meter Length
ASTM A312 TP304 is a seamless and welded austenitic stainless steel pipe built on the classic 18% chromium / 8% nickel chemistry. It delivers an excellent balance of corrosion resistance, toughness and formability, making it one of the most widely specified piping grades in the world.
Produced by hot piercing followed by cold rolling or cold drawing, every TP304 pipe is supplied in the annealed and pickled condition with tight dimensional control and a uniform, clean surface that suits both high-pressure and general corrosion service.
