The hardness and corrosion resistance of nickel alloys with molybdenum and tungsten

  • 44 Accesses

Conclusions

The newly-developed Ni−Mo−W corrosion resistant hard alloys (N65M20V15 and N55M20V25) have a corrosion rate of no more than 0.2 mm/year in 30% HCl at 60°C and in 70% H2SO4 at 90°C, with a hardness as high as HRC 52.

The alloys are precipitation-hardening. To obtain a high hardness it is recommended that they be heat treated by water quenching from 1000–1050°C and aging at 800°C for 4 h.
