Forging Die Steel is nickel hot work tool steel with good hardenability. uniform hardness over section also at great dimensions . Resistance under impact loadings. Very good strength and toughness. Good tempering resistance and dimensional stability. Tools can be water or air cooled. Application Forging tools, dies of all sorts, shapes and sizes, hot forging and pressing tools for steel and metal. Moulds, bushings, piercers etc. Blocks for dies, hammers and pile drivers, rams of power hammers, hot mill rolls, very hard, cold work dies and punches. Properties Physical properties (avarage values) at ambient temperature : Modulus of elasticity [103 x N/mm2]: 215 Density [g/cm3]: 7.84 Thermal conductivity [W/m.K]: 36.0 Electric resistivity [Ohm mm2/m]: 0.30 Specific heat capacity[J/g.K]: 0.46 Workability Forging Hot forming temperature: 1050-850oC. Machinability: The machinability rating of D3 is roughly 25 % that of free machining carbon steel 1018. Due to its abrasion resistant nature, machining in the hardened condition should be limited to finish grinding. Specification 01 Designation by Standards Ravne No. Mat.
