scope:

NEN-EN-ISO 683-17 specifies the technical delivery requirements for five groups of wrought ball and roller bearing steels as listed in Table 3, namely - through-hardening bearing steels (steels with about 1 % C and 1 % to 2 % Cr), - case-hardening bearing steels, - induction-hardening bearing steels (unalloyed and alloyed), - stainless bearing steels, and - high-temperature bearing steels. This part of ISO 683 applies to the products and heat-treatment conditions given in Table 1 and the surface conditions given in Table 2. In addition to this part of ISO 683, the general technical delivery requirements of ISO 404 are applicable.
