S.D.C. Steel

S.D.C. Steel

Steel name: S.D.C.
Diagram No.: 1623
Chemical composition in weight %: 0.36% C, 0.25% Si, 0.35% Mn, 5.00% Cr, 1.50% Ni, 1.75% Mo, 0.65% V
Steel group: Hot work tool steels
Properties: The S.D.C. steel is a new material for tools and more specifically die-casting moulds, with superior properties obtained as the result of the combination of several innovative actions: - a multi-scale approach for investigation in the microstructure, - a definition of an ideal microstructure by the understanding of relations between microstructure and its evolution under thermo-mechanical loading during service, - a new composition with a nickel addition and a precise adjustment of the balance between hardening elements and nickel, with a low level of trace elements - a specific production route with an optimised forging and annealing process, - a heat treatment with an accurate definition of parameters for austenising and tempering.
Applications: For large-size toolings used in die-casting applications with the objective of increasing the fatigue resistance of the material and the tool life.
Reference: Not shown in this demo version.
