Weld Mold® 9211-T
9211 is a solid wire used for welding 1% Cr – .5 Mo Creep resistant steels and C-Mn steels subject to heat treatment.
Applications
Commonly used on cast steels, boilerplates, quench and tempered steels, case hardening steels as well as corrosion resistance steels such as Core10. Occasionally used on Mold steels in less sever applications as an economical alternative to P-20.
Procedure
All areas to be welded must be free of cracks, oil, dirt and any other foreign matter. If someone has used the torch to weld any copper or aluminum based alloys the tungsten, cup, and collet must be replaced. Apply stringer beads, maintain interpass temperature, and use the smallest diameter electrode and least amperage consistent with good welding practices. Preheat to 400ºF. Preheat determines the rate of cooling, which in turn, drastically affects the ultimate RC hardness.
