ASTM A423 Gr1 is a specification that covers seamless and electric-welded low-alloy steel tubes for heat exchangers. These tubes are made from hot-rolled steel and are specifically designed to meet the requirements of heat transfer applications. The tubes are intended for use in both high-pressure and high-temperature environments.
The material used in ASTM A423 Gr1 tubes is a low-alloy steel, which provides superior strength and durability compared to standard carbon steel. The low alloy content enhances the heat transfer capabilities of the tubes, making them ideal for use in heat exchangers where efficient heat transfer is crucial.
