ASTM A210 (Grade A1 & Grade C) Seamless Boiler Tubes
High-pressure medium carbon steel seamless tubes engineered for utility power station water walls and superheater coils.
ASTM A210 / ASME SA210 Grade A1 & Grade C Boiler Tube
Starlight Tubes manufactures ASTM A210 / ASME SA210 seamless medium-carbon steel boiler and superheater tubes. With higher mechanical strength than conventional low-carbon boiler tubes, Grade A1 and Grade C tubes enable boiler designers to specify lighter wall thicknesses while maintaining full ASME Section I compliance.
Our A210 tubes are supplied in hot-finished or cold-drawn execution with stress relief or full annealing. Tested with 100% ultrasonic and eddy current inspection, hydrostatic testing, flattening, and flaring tests.

Frequently Asked Questions on ASTM A210 Seamless Boiler Tubes
Key engineering, tolerance, and international compliance answers from our metallurgical quality desk.
ASTM A210 has higher carbon content (up to 0.27% in Grade A1 and 0.35% in Grade C) and higher tensile strength (415-485 MPa vs 325 MPa for A192), allowing for thinner tube walls under equal pressure.
