BS EN 10027-2:2015

Designation systems for steels. Numerical system

Status : Current, Under review   Published : April 2015



1.1 This European Standard specifies a numbering system, referred to as steel numbers, for the designation of steel grades. It deals with the structure of steel numbers and the organization for their registration, allocation and dissemination. Such steel numbers are complementary to steel names set out in EN 10027‑1.

This European Standard is applicable to steels specified in European Standards. This European Standard may be applied to national steels and proprietary steels.


Although the scope of the systems is limited to steel, it is structured so as to be capable of being extended to include other industrially produced materials.

1.2 Steel numbers established in accordance with this system have a fixed number of digits (see Clause 5). They are better suited for data processing than steel names established in accordance with EN 10027‑1.

1.3 For steels specified in European Standards the application for allocation of steel numbers (see A.6 to A.9) is the responsibility of the ECISS Technical Committee concerned. For national steel grades, the responsibility is that of the national competent body.


Applications from European organizations having a specified interest in the standardization of steel and steel products (e.g. ASD, EUROFER) are submitted via the ECISS Central Secretariat (see A.9).
