View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.UNILOY 405 is a non-hardening modification of the 12% chromium stainless steel, AISI Type 410. A small addition of aluminum (about 0.20%) restricts the formation of austenite at high temperature so that hardening does not occur upon quenching. This characteristic makes Uniloy 405 especially suited for welding; the welds are ductile and there is no need for controlled cooling rates. Uniloy 405 provides good corrosion resistance and oxidation resistance to about 1200 F in applications not requiring the high strength of hardenable grades. Applications of Uniloy 405 include all types of welded structures that cannot be annealed after welding.
