AK-ER120S-G (TIG / MIG)

Standard：

EN ISO 16834-A: G894 Mn3Ni1CrMoM

AWS A5.28 ER120S-G

GB/T8110 ER80-G

Description: AK-ER120S-G is a solid welding wire with gas-shielded, used in nuclear power equipment manufacturing and pressure vessel manufacturing. Under the protection of argon- rich(80%Ar+20%CO2 ) gas, it has good process performance and mechanical properties, especially the welding seam In the state of long-term heat treatment, it can still ensure the excellent mechanical properties of the weld, and has good heat treatment resistance.

Application: It is mainly used for the welding of low-alloy steel specially used for the manufacture of nuclear power equipment, and can also be used for the manufacture of pressure vessels.
