Abstract
A predominantly austenitic chromium-nickel steel has the following composition: Cr 16-25 per cent; Ni 7-25 per cent; N up to 0.05 per cent; C up to 0.05 per cent; Fe together with residual deoxidizers such as Mn up to 3 per cent and Si up to 2 per cent forming the remainder, the maximum carbon content of a steel of selected chromium and nickel contents being ascertainable according to a formula set forth in the Specification. Within the above ranges alloy steels which are substantially 100 per cent austenitic after annealing at 1075 DEG C., air cooling, reheating to 650 DEG C. and air cooling, are selected by means of a nomograph accompanying the Specification. The alloy steels of the invention are substantially insusceptible to intergranular corrosion and may be used in the manufacture of welded articles and welding rods.
