Abstract

A shaped article which is manufactured b casting in air or under inert-gas shrouding at atmospheric pressure is disclosed. The shpaed articl eprovdies a surerior combination of high strength, hardness, ductility, and corrosion resistance compared to the known air. castable stainless steels. A cast article in accordance with this inveniton is made from a high strenght, astable, stainless steel alloy having the following weight percent composition C 0.1 max., Mn 2 max., Si 1 max., P 0.05 max., S 0.05 max., Cr 9-13, Ni 4-8, Mo 4-8, Co 8-16, N 0.1 max. The balance of the alloy is essentially iron and the usual impurities. A process for making such an article is also described.
