Heat-resistant high-strength mould material

Abstract

The invention discloses a heat-resistant high-strength mould material. The mould material comprises 1.4%-5.2% of C, 1.2%-5.0% of Si, 0.4%-1.2% of Mn, 0.01%-0.02% of S, 0.4%-1.0% of Cu, 0.6%-5.0% of Cr, 0.4%-4.8% of Ti, 1%-6% of Mg, 0.5%-3.0% of Al and 80%-96% of Fe in proportion. According to the heat-resistant high-strength mould material, the heat-conducting property is superior to that of steel, and the wetting property can be significantly improved through the Mg and the Ti which are added to the material; in addition, the material is free of brittleness, and the mechanical strength is close to that of the steel; graphite is a good solid lubricant, and hence the surface abrasion of aluminum and alloy of the aluminum can be reduced.

Description

technical field [0001] The invention relates to a material, in particular to a heat-resistant and high-strength mold material. Background technique [0002] In order to save energy, all countries in the world improve their efficiency by increasing heat and electric energy or heat and kinetic energy conversion machines, so that the materials of some supporting parts fail due to heat resistance and low strength. In addition, with the adoption of new processes for hot-pressed or hot-extruded plastic, non-ferrous metal or steel parts, the molding temperature and pressure increase, and the materials originally used to make molds can no longer meet the new performance requirements. [0003] For heat-resistant high-strength materials, steel is mostly used, but for molds with very high thermal conductivity requirements, steel molds are not as good as graphite molds, but graphite molds in the prior art still need to be improved in terms of heat resistance and strength.
