ASTM A376 TP347H Stainless Steel Seamless Pipe With Pickled And Annealed
ASTM A376 TP347H Stainless Steel Seamless Pipe for High-temperature Central-station Service
Alloy 347 stainless steel are austenitic stainless steels that contain stabilizing elements. This alloys is easily welded. Annealing may not be required after welding unless stress relief is desired. 347 stainless steel has excellent resistance to oxidation and corrosion. With high creep strength, 347 stainless steel work best up to 1600 °F.

Benefits of 347 Stainless Steel
- Higher creep stress and rupture properties when compared with 304
- Ideal for high temperature service
- Overcomes sensitization and intergranular corrosion concerns
- Can be used in elevated temperature applications for ASME Boiler and Pressure Vessel Code applications
- Due to stabilisation the material offers better overall corrosion resistance when compared to 304/304L
- Excellent mechanical properties
- A high carbon version (347H) is also available
Applications
- Food processing equipment, particularly in beer brewing, milk processing & wine making.
- Kitchen benches, sinks, troughs, equipment and appliances
- Architectural panelling, railings & trim
- Chemical containers, including for transport
- Heat Exchangers
- Woven or welded screens for mining, quarrying & water filtration
- Threaded fasteners
- Springs
- Others
