Originally developed as a high-strength alloy for the aircraft industry, this alloy was further developed and optimized to satisfy the most demanding applications of the mold construction industry. The resulting mold construction alloy, Hokotol, exhibits very high strength and wear resistance, as well as excellent uniformity of strength properties. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance.
