Table of EI and EF

As a rule, the ET table consists of two columns: the manufacturer's marking and the composition marking. This is sufficient to identify the manufacturer and the characteristic application area. The conventional designation of EI steel is deciphered as electrosteel exploratory steel. On a similar principle, the table of EP steel - electrosteel explorer. In some cases, you may find an additional section on the standards of GOST and T.U.
