Quenched and tempered steels not illustrated may be used as follows:

34 CrNiMo 6 like 30 CrNiMo 8
30 CrMoV 4 like 30 CrNiMo 8
42 CrMo 4 like 50 CrMo 4
36 CrNiMo 4 like 50 CrMo 4
50 CrV 4 like 50 CrMo 4
34 CrMo 4 like 41 Cr 4
28 Cr 4 like 46 Cr 2
C 45 like Ck 45
C 22 like Ck 22
C 60 and C 50 lie approximately between Ck 45 and 46 Cr 2.
C 40, 32 Cr 2, C 35 , C 30 and
C 25 lie approximately between Ck 22 and Ck 45.

Loading type I: static
