AWS A5.9: ER318 is a submerged arc welding wire intended for welding 19Cr/12Ni/3Mo stabilized Ti grades like 1.4571 / 316Ti. Also suitable for the welding of similar unstabilized grades 316 or 316L. AWS A5.9: ER318 is suitable for service temperatures from -120 °C to +400 °C and has high resistance to intergranular corrosion.

Suitable flux: WP 380

Flux type suitability is strongly dependent on its application. In combination with the wire electrode the most suitable flux should match the requirements of the plate material as closely as possible under the existing welding conditions. Further information can be obtained from the technical flux data sheets.
