Weld Mold® 420

---

Weld Mold 420 is a typical 420 Martensitic stainless steel.

Applications

This type of electrode is primarily used for overlaying and cladding of steel mill rolls and other steel mill components. 420 is also used in the die cast industry and overlaying when corrosion resistance, hardness and oxidation resistance is required.

Procedure

Clean all areas to be welded for best results. Base metal should be pre-heated between 400° and 600°F to avoid cracking.
