ABC Steel is an application for calculation of steel critical points and properties based on chemical composition.

Currently ABC Steel is able to carry out calculations of
- melting point of steel Tliq;
- Ac1 and Ac3 temperatures;
- martensite start temperature Ms;
- carbon equivalent Ce (two formulas have been used);
- nitrogen and manganese equivalents Neq and Mneq;
- HRC hardness of martensite.
