Selectarc MIG 27/31CU

This solid wire, designated ER383 according to AWS A5.9 and conforming to ISO 14343-A (G 27 31 4 Cu L), is specifically formulated for Gas Metal Arc Welding (GMAW) of entirely austenitic stainless steels such as Ur B28™ and Sanicro 28*. It exhibits exceptional resistance to attacks from phosphoric and sulfuric acids, alongside a high level of protection against pitting corrosion and stress corrosion in chloride-rich environments. The wire’s composition (ranging from 1.0% to 0.025% Carbon) ensures optimal weld performance. Back shielding with Argon, Nitrogen, or a copper backing support is recommended to prevent ‘back end’ rust.

This wire is primarily utilized in the chemical and petrochemical industries for welding entirely austenitic stainless steel components. It’s ideal for applications requiring resistance to corrosive environments. The recommended welding parameters (current, voltage, shielding gas flow rate) are provided for optimal GMAW results. Using a copper backing support is advised for added protection during the welding process.
