ASTM A249 TP347H Austenitic Stainless Steel Tube For Power Plants
Specifications
ASTM A249 TP347H welded austenitic stainless steel tube specifications include a high-carbon grade for high-temperature service, suitable for boilers and heat exchangers. These tubes have a specific range of outer diameters 6.0mm to 914.4 mm and wall thicknesses 0.3 mm to 50mm, and must be cold-worked after welding and undergo solution heat treatment. They are used in applications requiring excellent creep strength and resistance to oxidation and intergranular corrosion at high temperatures.
