Product Description

ASME SA210 Gr.A1 Boiler Steel Pipe Heat Exchanger Tubes

Description

ASME SA210 Gr. A1 Boiler Steel Pipe is a seamless, medium-carbon steel boiler tube designed for high-temperature, high-pressure applications like boilers, superheaters, and heat exchangers, offering good ductility and toughness with key properties including minimum 415 MPa tensile strength, 255 MPa yield strength, and strict chemical/dimensional tolerances, conforming to ASME standards for safe energy production.
