Element equivalent : C eq, Creq, Nieq, Weq, Mneq......what else ? 1

[stanislasdz]

In the field of the metallurgy there many element-equivalent :

For instance :

Ceq is used in the welding
Creq and Nieq in the Staniless Steels
Weq in the tool steels

2 questions :

- I heard about Mn eq ; in what field we use the manganese equivalent ?

- General question : is there another element équivalent ?

Happy new year to all

I do not know about Mn equivalent.

For titanium alloys, there is the molybdenum equivalent for calculating beta-phase stabilization.

From my days in the pits.
C_eq's and Mn_eq's were used to help determine the tensile strength of open hearth steel. P factors in the equation also.

C_eq's and Mn_eq's are used to improve the permeability of silicon steels.

Agree with unclesyd regarding the Mn _eq.
