AK-ER55-1CM-MnV
Standard:
AWS A5.18 ER80S-G
GB/T 8110 ER55-B2-MnV
Description: AK-ER55-1CM-MnV is a gas shielded welding wire for 1%Cr-0.5%Mo pea-rlitic heat resistant steel. It uses CO2 or Ar+5%-20%CO2 for gas shielding. The dep-osited metal has good mechanical properties.
Application: It is suitable for the welding of 1%Cr-0.5%Mo heat-resistant steel with a welding working temperature below 530℃, and is often used in the welding of con-ventional thermal power stations, petrochemical equipment and other structures.
