Abstract
Castings of carbon 0.25/0.8, nickel 8/62, chromium 12/32, tungsten 0.05/2, titanium 0.05/1, balance iron (substantially) of austenitic microstructure, essentially free of cobalt and molybdenum, and not requiring heat treatment to develop service properties considerably improved compared to standard ACI alloy grades.
