Techalloy 312 description:
Top Features
Techalloy 312 is used to weld cast and wrought alloys of similar compositions. The electrode can also be used for joining hard to weld materials and
dissimilar metals. Applications should be limited to 800°F (420°C). The weld deposits exhibit high tensile strength and offer some resistance to abrasion.

Typical Applications
Tool steels
Hard to weld steels
Cast and wrought alloys
Dissimilar metals
