ASTM A249/ASME SA 249 stainless steel pipe condenser coil tube

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:

● Boiler

● Superheater

● 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,  reverse-bend test, hardness test, and hydrostatic or nondestructive test.
