Application
DURAMAX HAST-X (ENiCrMo-2) is a solid-solution-strengthened super alloy that combines very good high-temperature strength with very good resistance to oxidizing environments up to about 2000°F (1095°C), and good carburization resistance. This electrode is used for the welding of Hastelloy X and similar nickel-chromium-molybdenum alloys. It is also used for surfacing of steel. This alloy is one of the most widely used materials for fabricated or forged parts in gas turbine engines, and is also used in chemical and petrochemical plant, power plant and industrial heating applications.
DMHAST-X may be cold-formed or hot-formed by various techniques, and is readily weldable by most standard methods.
