Heat-treated steels, alloy steels and free-cutting steels. Ball and roller bearing steels (British Standard)
ISO 683-17:2014 specifies the technical delivery requirements for five groups of wrought ball and roller bearing steels: 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.
