Density and specific heat of high-speed steel. Physical and mechanical properties.

Density and specific heat of high-speed steel. Physical and mechanical properties.

Are you interested in the density and specific heat of high-speed steel? Supplier Avlob offers to buy high-speed steel at a bargain price. The supplier guarantees the timely delivery of products to any address in Europe or abroad. Regular customers receive a discount discount. The price is the best in this segment.

Technical specifications

A finished tool made of high-speed steels should have the following set of properties:

  1. High surface hardness (for a metal-cutting tool it is = 68… 69 HRC, for a stamping tool = 65… 66 HRC);
  2. Heat resistance at operating temperatures 300… 350 ° С;
  3. Impact toughness, which guarantees serviceability in the presence of bending stresses
  4. High wear resistance in friction conditions.

Heat treatment

In martensite, after quenching, the number of high-strength intermetallic compounds increases. The structure after quenching and high tempering, during which the separation of vanadium, chromium, tungsten, molybdenum carbides occurs is ledeburite. It is obtained as a result of dispersion hardening. The necessary viscosity indexes (including, in the core layers of the tool), high-speed steels are acquired as a result of a reduction in grain size and the preservation of a high degree of dispersion of carbides.

Relevance

Tool steel is characterized by increased values of hardness, strength and wear resistance. It is used in the following branches of machine building and metalworking:

  1. High-speed machining by cutting of complex structural steels;
  2. Cold reverse extrusion on presses with high degrees of deformation.
  3. Large bearings, operated at constantly elevated temperatures.

High-speed steels are inefficient with significant dynamic and shock loads: their relatively coarse-grained structure provokes the development of surface and deep cracks. The supplier Avlob offers to buy stamp steel at a bargain price. The price is the best in this segment of rental.
