The invention alloy has the following by-weight composition: -carbon 0.05 to 0.60% -nickel 20 to 55% -chromium 15 to 40% -silicon 0.5 to 2% -manganese 0.5 to 2% -nitrogen 0.03 to 0.20% -niobium 0 to 2% -tungsten and/or molybdenum 0 to 5% -aluminium 2 to 8% -copper 0 to 5% -iron and usual impurities -in as small quantities as the balance -possible - an increased resistance to carburization is obtained by endogenous formation of a barrier opposing the penetration of aluminium. |
