Available product shapes: Long Products, Open Die Forgings
Tool steel that has proved highly satisfactory for hot and cold work and long-time service up to approx . 450°C (842°F) in various fields of application. Tools for hydrostatic presses, cold extrusion tools, cold heading and embossing tools, molds for the plastics industry, die casting tools for aluminium and zinc alloys, hot pressing tools, cold pilger mandrels.
This results in the following advantages: High tensile strength and excellent yield point ratio, satisfactory toughness (reduction of area, elongation, impact strength, fracture toughness) even at low temperatures, superior notched tensile strength and heat checking resistance, practically no size change in heat treatment, no decarburization, no cracking, full hardening even in sizes above average. Convenient machinability in the solution annealed condition (machining is also possible in the precipitation-hardened condition). Good cold forming properties owing to reduced susceptibility to work hardening, eminent weldability, simple heat treatment at low temperatures.
