Description

Product Description

ASTM A335/A335M,ASME SA-335/SA-335M tubes are seamless ferritic alloy steel tubes for high temperature environments, which can be formed by bending, crimping, and similar processes, and are also suitable for fusion welding. Tubes are available in a wide range of material grades (chemical composition) (P1 to P911), as detailed in the product standards, and are manufactured by hot forming or cold drawing processes.
