Abstract

Stainless steel alloy composition. The stainless steel alloy composition includes rounded carbides and free chromium in a ferrite matrix. The rounded carbides have particle sizes under 5 microns. The rounded carbides include a first quantity of niobium-containing carbide and a second quantity of chromium carbide, and are substantially free of large, irregularly-shaped carbides.
