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.VASCO WEAR is an air-hardening, cold-work die steel developed to provide high resistance to wear at exceptionally good levels of toughness. It also has the high compressive strength necessary for maximum resistance to upsetting. Its many uses include such applications as thread-rolling dies, punches and blanking dies.
