Introduction to Steel Grades. Steels are impure iron-carbon alloys of low carbon content, usually 0.1–1.5% carbon by weight. The amount of carbon and level of 

Designation of a steel grade according to DNV GL rules and standards. The EN range of steel specifications was first introduced in 1941 as the War Emergency, British Standard Schedule BS970. With the assistance of the Technical  5 Jun 2015 About grade steel.

Vacuum arc remelted stainless steel billets with low contents of impurities, thus VAR (vacuum arc remelting) and 'HV' is added to the steel grade designation.

Features of European steel and alloy database. Steel numbers - Listing of all steels according to steel classification standard EN 10027-2. Steel and cast iron standards - Listing of all steels mentioned in standards. Alloy standards - Listing of all alloys mentioned in standards.

En designation of steel

According to the AISI classification, steels can be divided into different series. Second digit: 0 (carbon steel), 1 (resulphurized carbon steels, 2 (resulphurized and rephosphorized carbon steels) Third and fourth digits: carbon content *100.

The heat treatment (temper) designation system of EN 515 is used for all forms of wrought aluminium and aluminium alloys. Property (mechanical or physical) limits apply to individual alloy-temper-product combinations. Basic temper designations consist of letters (F, O, H, W, T).

eg. S275 is a structural grade steel with a minimum specified yield stress of 275 N/mm2. Structural and pressure vessel steels have a standardised naming convention and this is laid out in EN 10027 Designation System for Steels. Whilst both are similar they are each subtly different and it is important to know what all the components of a steel name mean EN Structural Steel Names to EN 10027 The EN standards cover a wide range of materials including hot and cold rolled carbon and alloy steels, plates, sheets and strips, spring steels, heat treatable steels, castings, stainless and heat resisting steels, electrical steels etc. The EN is concerned with the standardization of the manufacture, chemical composition and mechanical characteristics of steel products. UNI stands for Ente Nazionale Italiano di Unificazione, it is an association that performs regulatory services in Italy. UNI’s designation for steel and aluminum alloys are similar to EN and ISO designations.
