STAVINOX 307Si

STAVINOX 307Si

The MIG and TIG versions of STAVINOX 307Si are high-performance austenitic stainless steel filler materials made for tough welding jobs. This 307Si welding wire suits the joining of dissimilar steels, including unalloyed steels, austenitic stainless steels and heat-resistant steels, and it also performs well on hardening and tempering steels such as ballistic and armour plates. Added silicon improves the flow of the weld pool, leaving a smooth, clean weld finish.
