Description: AK-ER62-B3 M is a gas shielded welding wire for 2.25%Cr-1%Mo pear-litic heat-resistant steel. The welding wire uses Ar+(1%-5%)CO2 for gas shielding and has good mechanical properties of deposited metal.
Application: It is suitable for the welding of 2.25%Cr- 1%Mo heat-resistant steel (such as T/P22, 15Cr2Mo1, etc.) whose working temperature is below 550℃ . It is often used in the welding of conventional thermal power stations, petrochemical equipment and other structures.
