Product Description

ASTM A249 SUS310 Welded Tubing:

The ASTM A249 SUS310 Welded Tubing specification covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels. More specifically, the ASTM A249 specification is intended for uses such as:

Boiler

Superheater

heat exchanger

condenser tubes

be furnished in the heat-treated condition in accordance with the required solution temperature and quenching method. conform to the prescribed tensile and hardness properties such as tensile strength, yield strength, elongation, and Rockwell hardness number.

undergo mechanical tests such as tension test, flattening test, reverse-bend test, hardness test, and hydrostatic or nondestructive test.


Typical compositional ranges for ASTM A249 SUS310 Welded Tubing are given in table 1.

Corrosion Resistance

Excellent in a wide range of atmospheric environments and many corrosive media. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60°C. Considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 60°C.
