General Terms

Until 2014, inclusive, in the European Union, the production of bearing steel alloys were defined by DIN 17230, which directly corresponded to the technical norms and requirements of domestic GOST 801-78. However, this information was further transferred in a slightly modified form to ISO 683-17:2015 "Thermally modified steels, alloyed and high-speed steels, part 17: steels for ball and roller bearings". Thus, ISO 683-17:2015 defines the technical requirements for supplying the following groups of ball and roller bearing steel alloys machined by forging and rolling:

  1. High-carbon steels containing about 1% carbon and 1 to 2% chromium, which are hardened by heat treatment;
  2. Bearing-hardenable steels melted in electric induction furnaces (applies to all types of steels, both alloyed and unalloyed);
  3. Stainless steels, heat resisting steels;
  4. Bearing steels designed for high-temperature applications.

According to this standard, the general properties of bearing steel alloys are:

  1. High carbon and chromium content;
  2. a high carbon and chromium content; a high strain-hardening tendency during rolling;
  3. increased hardness, which can reach 60...67 HRC;
  4. Working ability at temperatures up to 120 °C;

Evek GmbH offers to buy a wide range of bearing steel at an affordable price. We will provide delivery of products to any point of the continent. The price is optimal.
