Supplier KMZ offers steel round, rod and wire of high carbon tool steels brand 5KH3V3MFS (DI 23) at the economical price. The provider ensures timely delivery of products at any address specified by the consumer. The price is the best in this segment of the rental.

Technical characteristics

Complex-alloyed medium-carbon steels steel 5KH3V3MFS (DI 23) refers to a category of steels with high heat resistance, and is intended for the manufacture of die inserts stamps of hot deformation. The characteristic feature of this steel — increased the total content of tungsten and molybdenum. After initial hardening strength steel saves up to heating temperatures of 650…680°C; at higher temperatures the steel intensively ezuprechnaya.

Application

Heavy-duty dies, hot pressing, mechanical and hydraulic equipment on which operations are performed, forging, upsetting, upsetting and extruding alloy and high carbon steels.

Physical properties

  • Density, kg/m3 — 7800;
  • Coefficient of thermal conductivity, W/mgrad — 10,2;
  • The coefficient of thermal expansion, µm/deg to 9.5.
  • The limit of temporary resistance, MPa — 1680;
  • Yield strength, MPa — 1500;
  • Relative tensile elongation, % — 8;
  • The relative narrowing of the cross-sectional area, % — 38;
  • Hardness after annealing Brinell, HB — not more than 241;
  • Impact strength, kJ/m2 — 250.

Treatment

The steel has a minimum tendency to heat softening. Heat treatment — hardening+vacation. The temperature range 850-forged…1180°C, With subsequent slow cooling of the forgings in the well. Weldability is bad. The material is sensitive to obrazovaniu placenow, is not inclined to temper brittleness.
