/glossary/sa210ASME specification for seamless medium-carbon steel boiler and superheater tubes.
In detail
SA-210 is the ASME specification for seamless medium-carbon steel boiler and superheater tubes. It includes two grades: Grade A-1 with minimum tensile strength 415 MPa, and Grade C with higher carbon content and tensile strength 485 MPa. The standard governs tubes up to 127 mm OD with maximum wall thickness 12.7 mm, and requires strict dimensional tolerances and heat treatment. SA210 is the default specification for high-pressure boiler tubes in Indian power plants and sugar mills.
Where you'll meet this in procurement
You will meet SA210 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 SA210 call-out on the RFQ before you lock commercial terms.
