1 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.
2 This part of ISO 683 gives the technical delivery requirements for five groups of wrought ball and roller bearing steels as listed in Table 3, namely:
a) through-hardening bearing steels (steels with about 1 % C and 1 % to 2 % Cr);
b) case-hardening bearing steels;
c) induction-hardening bearing steels (unalloyed and alloyed);
d) stainless bearing steels;
e) high temperature bearing steels.
3 In special cases variations in these technical delivery requirements or additions to them may form the subject of an agreement at the time of inquiry and order (see annex A).
4 In addition to this part of ISO 683, the general technical delivery requirements of ISO 404 are applicable.
