Designation

These steels belong to tool steels, but are distinguished by increased values of their hardness, strength and wear resistance their composition and properties are regulated by GOST 19265-73. High-speed steel refers to tool steels of special application. It is used in the following branches of machine building and metal working:

• High-speed cutting machining of complex alloyed structural alloys;
• Cold back extrusion on presses with high degrees of deformation.
• Large bearings at continuously elevated temperatures.

Shock loads.

High-speed steels are ineffective with high impact loads: their relatively coarse-grained structure promotes the development of surface and underlying cracks. Evek GmbH offers a wide assortment of high-speed steels at affordable prices. We provide delivery of products to any place on the continent. The price is optimal.

Properties

Finished tools made of high-speed steels should have the following set of properties:

• High surface hardness (for metal-cutting tools it can reach 68...69 HRC, for stamping tools - 65...66 HRC);
• Heat resistance at service temperatures, which reaches 300...³⁵⁰⁰ С;
• Sufficient impact toughness guaranteeing serviceability under bending stresses (though high-speed steels lose to tool alloyed ones in this aspect);
• High wear resistance under conditions of permanent contact friction stresses, including the lack of technological lubrication.

Achievement of such properties is promoted by the chemical composition and microstructure of all grades of high-speed steels. A significant amount of high-strength tungsten carbides as well as intermetallic compounds are permanently present in the quenching martensite, and the structure itself is a ledeburite. It results from dispersion hardening after quenching and high tempering, during which carbides of all carbide-forming elements - vanadium, chromium, tungsten, molybdenum - are released.

Viscosity

The required values of toughness (including the core layers of the tool) the high-speed steels acquire as a result of reducing the grain size and maintaining a high degree of dispersion of carbides. A favorable combination of toughness and hardness properties is provided by self-hardening of the steels under consideration, for which their steel has a sufficiently high chromium content. Vanadium and nickel give these steels the necessary toughness. However, the amount of nickel in the high speed steels is limited. Because this element increases the percentage of residual austenite, for which the high speed steels have to be repeatedly tempered.
