1 Scope
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.
