ASTM A213/ASME SA213 TP347H Stainless Steel Seamless Tube
YUHONG GROUP specializes in ASTM A213 TP347H Stainless Steel Seamless Pipe with 33 years’ experience. Our clients cover 70 countries all over the world. We offer high quality, lower cost but the best service.
ASTM A213 TP347H stainless steel tubes is advantageous for high temperature service because of its good mechanical properties. Alloy 347H Stainless Steel Tube offers higher creep and stress rupture properties than Alloy 304 and particularly Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerned. The 347H Stainless Steel Pipe has a high resistance to prolonged heat and corrosion making it well suited for engine, power generation, welded fabrications and other high heat applications. 347 stainless steel offers good mechanical properties with higher creep and stress rupture characteristics than other grades, such as 304. 347 stainless steel is also advantageous in applications that require omission of the annealing process after welding.

TP347 / TP347H Stainless Steel Heat Treatment
Annealing:Heat to 1850/2000°F (1010/1093°C) and quench in water. Brinell hardness approximately 150.
Hardening:Cannot be hardened by heat treatment, it can only be hardened through cold working.
Stabilizing:If temperature during use is expected up to 1600°C stabilizing between 1550/1650°F (843/899°C) can be used for optimum intergranular corrosion.
347/347H Stainless Steel Machinability: When machining 347 its chip is tough and stringy, use rigid tooling with heavy cuts to prevent work hardening.
Benefits of 347 TP347H 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
