SA 210 Grade A1 is a seamless medium-carbon steel boiler tube manufactured to ASME SA210 / ASTM A210 specification for boiler and superheater applications. This grade uses medium-carbon steel with silicon additions, offering a good balance of strength, toughness, and weldability for moderate-temperature boiler service up to 450°C.
SA 210 Grade A1 boiler tubes are used in water tube boilers, economizers, superheaters, and heat exchanger tubing in power generation, district heating systems, and industrial steam production. They are widely specified in thermal power plant boiler circuits and industrial process steam generators where a cost-effective alloy steel is required.
Spark Steel supplies ASME SA210 Grade A1 seamless boiler tubes with tensile strength minimum 415 MPa and yield strength minimum 255 MPa, available in OD from 12.7 mm to 114.3 mm with various wall thicknesses. Supplied in normalized condition with hydrostatic test, flattening test, and flaring test results per ASME SA210 requirements. Full mill test reports available with third-party inspection on request.
