ASME SA213 TP347H 1.4912 Seamless Tube Heat Exchanger Steam Boiler
ASME SA213/213M covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes.
Because of the stable element Nb, it has good intergranular corrosion resistance, high endurance strength and oxidation resistance, as well as good technological properties such as bending and welding.
ASTM A213 Grade 347H stainless steel tube is the most widely used commercial grade of stainless steel supplied into numerous industry sectors which also referred as WNR 1.4961 Seamless Tube.
YUHONG GROUP is specialized in supplying ASME SA213/213M Stainless Steel tubes Grades TP347, TP347H; ASTM A213 TP347, TP347H Seamless Steel tubes.
