ASTM A249 Specifications
The ASTM A249 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:
- heat exchanger
- condenser tubes
Upon complete, the material shall :
- 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, flange test, reverse-bend test, hardness test, and hydrostatic or nondestructive electric test.
