Product Description

ASTM A790/A790M-24:Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe

Application for Boiler, Superheater, Heat-Exchanger, and Condenser Tubes Standard Specification for Welded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes

Economic Advantages of ASTM A790/A790M Products: Lower Total Cost of Ownership (TCO)
The economic benefits of ASTM A790/A790M duplex stainless steel pipes are not limited to the initial procurement stage. Instead, they achieve a significantly lower Total Cost of Ownership (TCO) compared to conventional stainless steel (e.g., 316L) and carbon steel pipes by extending service life, simplifying installation, and eliminating additional treatments.
