Universal steel grade 4x5mfs is intended for the manufacture of tools and molds operated under high temperature loads. It retains its strength characteristics even under significant heating, and this material is characterized by excellent thermal conductivity and increased resistance to the formation of hardening cracks. Steel is geometrically stable, easy to process, and highly polished. 4x5mfs grade metal is made of:molds for plastics, dies for pressing aluminum, molds designed for injection molding of light alloys, dies for mechanical and friction presses. 4x5mfs strips can be made of low-alloy metals of increased strength or carbon steels, in accordance with the requirements of GOST 103-76. They are widely used in such areas as the construction of industrial workshops and household facilities, decorative interior decoration.High-speed steels and their characteristics One of the most important properties of such metals can be considered hot hardness. For example, P18 steel remains very strong even under significant heating (up to 500-600 ° C). For this reason, a tool made of high-speed steel will be more productive than a carbon steel device. An equally important characteristic of p18 steel is its redness, which is its ability to withstand significant temperature loads without changing its physical and mechanical characteristics. Fracture resistance is also important (under static, dynamic, or bending loads). The higher the strength of the metal, the more effort the working part of the tool can transfer. The red resistance of p18 grade metal increases as a result of alloying steel with molybdenum, tungsten, vanadium or other carbide-forming elements. These substances bind all the carbon present in the metal into special carbides, which are transformed into a solution during quenching. High-speed tool steel P6M5 has the following distinctive features: high stability of chemical properties, ability to work under conditions of significant heating, reduced deformation (due to repeated hardening). During the production process, P6M5 steel is heated to a temperature of 1210-1230C. This is necessary to obtain highly alloyed austenite and completely dissolve the secondary carbides present in the composition. When quenching the workpiece, it is required to provide a long exposure time - from 8 to 9 seconds for each millimeter of its diameter. After quenching, P6M5 steel is subjected to triple tempering, which causes dispersed hardening and transformation of residual austenite into martensite. The cutting properties of the finished tool can be significantly improved by nitriding at a temperature of 550-560C.
