ASTM A210 Boiler Tubes Price

ASTM A210 boiler tube pricing is ₹85 and ₹300 per kg or $0.60 to $2.15 per kg. The final price depends on grade selection (A-1 or C), outside diameter, wall thickness, length, order quantity, and current steel market conditions. Cold-finished tubes cost more than hot-finished tubes because of the additional processing and heat treatment steps involved. We provide competitive rates for both project orders and bulk supplies.

Industrial Applications of ASTM A210 Boiler Tubes

ASTM A210 / ASME SA-210 seamless tubes serve three primary sectors. Their medium-carbon composition and elevated-temperature strength make them suitable for the following applications.

Power Generation and Thermal Plants

ASTM A210 tubes are installed in boiler water walls, economisers, and low-temperature superheaters in coal-fired, gas-fired, and waste-heat recovery power plants operating below 500° Celsius. .

Petrochemical and Refinery Applications

Refinery process heaters and catalytic cracker units use these tubes for fired heater coils and steam generation systems, where medium-carbon steel provides adequate strength at moderate temperatures.

Heat Exchangers and Condensers

SA-210 Grade A-1 and Grade C tubes function as heat transfer elements in shell-and-tube exchangers and surface condensers across industrial and process plant installations.

ASTM A210 Grade A-1 and Grade C Comparison

ASTM A210 covers two grades: Grade A-1 and Grade C. Grade C has higher carbon content (up to 0.35% vs 0.27%) and higher minimum tensile strength (485 MPa vs 415 MPa) compared to Grade A-1. Grade C is selected for higher-pressure boiler service where greater strength is required.
