Heat-treated steels, alloy steels and free-cutting steels. Ball and roller bearing steels | Status: Current

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.
