Würth 312 is a solid wire designed specifically for MAG welding of stainless steels. Made from austenitic stainless 29Cr-9Ni alloyed steel, it is ideally suited for welding similar steels. The product is an excellent choice for welding dissimilar joints of unalloyed and stainless steels, and it can also be used for welding and cladding difficult-to-weld steels. It can also be used for buffering layers in tools prior to cladding, as well as for wear surfaces requiring resistance to heavy impact.
- Solid wire for welding stainless steels, so-called repair welding wire
- Made of austenitic stainless steel alloyed with 29Cr-9Ni
- Designed for welding stainless steels of similar composition
- Especially suitable for welding dissimilar joints non-alloy/stainless steel
Typical applications include, for example:
- For welding and cladding difficult-to-weld steels
- Buffer layer before coating in multilayer applications
- Wear parts requiring resistance to heavy impact
