ASTM A249 TP304 1.4301 Stainless Steel Welded Tube For Oil Service

ASTM A249 TP304 1.4301 Stainless Steel Welded Tube For Oil Service

What is ASTM A249?

This guide specifies standard specification for nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels with various grades intended for such use as a boiler, superheater, heat exchanger, or condenser tubes. Heat and product analysis shall conform to the requirements as to chemical composition for carbon, manganese, phosphorous, sulfur, silicon, chromium, nickel, molybdenum, nitrogen, copper, and others.

All materials shall be furnished in the heat-treated condition in accordance with the required solution temperature and quenching method. When the final heat treatment is in a continuous furnace, the number of tubes of the same size and from the same heat in a lot shall be determined from the prescribed size of the tubes. 

YUHONG Groupo is one of the large suppliers for high quality ASTM A249 / ASME SA249 Tube. Our ASTM A249 Tubing Specification for nominal-wall-thickness welded tube and heavily cold worked welded tube made from the austenitic steels with various grades intended for such use as a heat exchanger, boiler, superheater or condenser tube.

ASME SA249 material shall conform to the prescribed tensile and hardness properties such as yield strength, tensile strength, elongation and Rockwell hardness number. Also, each ASTM A249 Tubing, astm a249 tube undergo mechanical tests such as flattening test, tension test, flange test, reverse-bend test, hardness test, and hydrostatic or nondestructive electric test.
