LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
ASTM A312 TP304 is an austenitic alloy grade with excellent corrosion resistance, oxidizing media properties and excellent mechanical properties. A312 TP304 pipe is usually formed from round raw material blanks by push or pull, which is more corrosion resistant than ordinary 304 stainless steel pipe. ASTM A312 Grade TP304 Pipe can be processed by hot rolling or cold rolling process. A312 Gr TP304 Pipes can be produced in seamless, welded and ERW configurations to allow their use in different applications.We can provide you with different sizes to suit your project requirements.

Seamless pipe start from steel billet, billet is semi finished product, it should be inspected prior to processing, choosing superior quality material, and proper billet sizes, common sizes range from 50 - 280, special size for special seamless pipe size can be offered.
To achieve precise seamless pipe, cold rolling and cold drawing process reduce outside diameter and wall thickness, gradually form required seamless pipe.
All the seamless pipes should be heat treated under required temperature, after cold worked, residual stress have been caused, and potential impurities may be occur, heat treatment rebuild alloy structure, then obtain original properties. TP304 stainless steel minimum annealing temperature should be 1040 degree C.
Tolerance: ASTM A312 specification specified outside diameter and wall thickness limitations, OD tolerance conform to ASTM A999.
