This document 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 document is applicable to the products and heat-treatment conditions given in Table 1 and the surface conditions given in Table 2.
