ASTM A249/A249M - Standard Specification for Welded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes

Scope  
This standard covers welded austenitic stainless steel tubes for high-temperature service in boilers, superheaters, heat exchangers, and condensers. It includes both seamless and welded tubes, with dimensions specified in ASME B36.19M.
Stainless steels (particularly austenitic grades like 310, 321, 347) retain strength at elevated temperatures (up to 1000°C+ for some grades).
Carbon steel loses strength rapidly above 400-500°C and is prone to scaling and decarburization.
Stainless alloys with Ti/Nb (321/347) resist sensitization and carbide precipitation in high-temperature service.
