700HT offers a harder weld deposit than USA 600 HT with lower corrosion resistance. Primarily used for high metal to metal abrasion. Weld deposits are martensitic in structure and will work harden when put into service. Bonds well with fatigued or older hard-faced deposits and
preheat/interpass of 300-500°F may yield superior properties. Typical applications would include the hard surfacing of rollers, conveyor screws, crusher rolls and mill hammers.
