Abstract
A ferrous alloy, particularly suitable for hard facing purposes and for use in the form of castings, has the following composition: C 3-5 per cent, Ni 1.7-10 per cent, Cr 9-22 per cent, Si 2-5.5 per cent, Fe the balance. The proportions of nickel and silicon are further selected within the above range in accordance with the following schedule: .Ni.Si .1.7- 3 per cent.2 - 3.5 per cent .3 - 5 per cent.3.5- 4.5 per cent .5 -10 per cent.4.5- 5.5 per cent The alloy may also contain 0.2-5 per cent of copper
