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. The addition columbium plus tantalum in 347 stainless steel give some desired characteristics like:
(1)Prevents harmful carbide precipitation in the heat affected zone (HAZ) of the weld area
(2)Imparts substantial immunity to intergranular corrosion
(3)Reduced embrittlement in the HAZ of the weld area
347H stainless steel plate is a very stable stainless steel. When the temperature reaches 800-1500 ° F (427-816 ° C) and chromium carbide precipitates, it can still maintain good resistance to intergranular corrosion. Due to the addition of titanium to the composition, 347H can still maintain stability in the case of chromium carbide formation. 347H stainless steel has advantages in working under high temperature due to its excellent mechanical properties. Compared with 304, 347H stainless steel has better ductility and resistance to stress fracture.
Candidates are also important in many cases. For example, if ordinary stainless steel (such as 304) is used instead of special stainless steel in daily use in a high temperature or high corrosion environment, ordinary stainless steel (304) is not suitable for this. High temperature oxidation.
