ASTM A213 TP304 Seamless Austenitic Alloy Steel Boiler,SuperHeater and Heat Exchanger Tube
We are Yuhong Group,one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 33 years, and sells steel pipes every year more than 80000 tons. we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.
Description
ASTM A213 specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes. Grades containing the letter H in their designation have requirements different from those of similar grades not containing the letter H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements. The tubes shall be made by the seamless process and shall be either hot finished or cold finished, as specified.
