SA213
/glossary/sa213ASME specification for seamless ferritic and austenitic alloy steel boiler tubes.
In detail
SA-213 is the ASME specification for seamless ferritic and austenitic alloy steel boiler, superheater, and heat-exchanger tubes. It covers multiple grades including T11 (1.25Cr-0.5Mo), T12 (1Cr-0.5Mo), and T22 (2.25Cr-1Mo) for high-temperature service up to 650°C. The standard mandates stringent chemical analysis, mechanical testing, and non-destructive examination, making it essential for superheater and reheater tubes in thermal power stations and high-pressure process plants.
Where you'll meet this in procurement
You will meet SA213 when a buyer, consultant, or mill quote names a governing specification. Confirm which revision applies, what tests the standard requires, and whether the grade on the MTC actually matches the SA213 call-out on the RFQ before you lock commercial terms.
