Introduction

Since 1988 a new series of 'mandatory' European standards (EN = Europaischen Normen) has been created, to replace national standards, such as BS, DIN, SS and NF, throughout 18 countries of Western Europe. EN are a part of the 'Single Market' legislation, designed to give equal opportunities for firms to compete throughout Europe, by harmonising the technical requirements between countries. The national standards bodies, of which BSI is one, are required to officially withdraw their national standards, when an EN is created with the same scope of application.

Consistent pattern of StandardsThe aim is to produce a logical, common pattern,in which items are standardised in one document only, reference being made to this document from other standards. For example, tensile testing methods are standardised in a different document to material property values, and dimensional tolerances in other separate standards. Thus, changed requirements need only to be written into one document.

Implementation of ENThe fact that BSI and the other national bodies publish EN does not compel people to use them. (Note the continued use of the BS 'Emergency Number' (also EN) series of steels years after they have been officially replaced}. Only when suppliers and customers fully accept and understand European Standards, will it actually happen.

Review of Standards

BS EN 10079:1992- Definition of steel products..

This standard is essentially a reference standard which defines steel products according to : a) Their shape and dimensions : b) Their appearance and surface condition. The standard simply provides agreed definitions of steel products and typically includes sections on ingots and semi-finished products, flat products, electrical steels, long products.

BS EN 10027-1:1992 Designation systems for steel. Steel names, principal symbols

This is a steel material designation system based on names. These names consist of alpha numerical characters and define two main groups of steels

Steels Designated On The Basis Of Their Use And Their Mechanical Properties.

A number of letters with their mechanical property identifiers are listed below

Letter Steel Use Mechanical Property...S Structural Steel Minimum Yield StrengthP Pressure Purposes Minimum Yield StrengthL Line Pipe Minimum Yield StrengthE Engineering Minimum Yield StrengthB Reinforcing Steel Characteristic Yield CaseY Pre-stressing Steel Minimum Yield CaseR Rails Minimum Yield CaseH High Strength Cold Rolled Minimum Yield Case

D Flat Products for Cold Forming C, D or X followed by two numbers characterising steelT Tinmill Products Nominal Yield Case

M Electrical SteelNumber = 100 x specific loss in W/kg, "—" Number = 100 x nom thick in mm Letter for type of steel (A,B,E,N,S or P)

e.g. S420 designates a structural steel(S) with a specified yield strength of 420MPa(420)

Steels Designated On The Basis Of Their Chemical Composition ....

—Non alloy Steels ..The relevant coding consists of a C followed by two numbers = 100 x Carbon content.

—Non alloy Steel with Manganese content => 1%, non alloy free cutting steels and alloy steels except HSS where content of all alloys =< 5%... The relevant coding consists of 100 x Carbon % content then Chemical symbols indicating most important alloys then number indicating the associated % contents.

—Alloy Steels.. The relevant coding consists of an X then 100 x Carbon % content then chemical symbol indicating most important alloys. then numbers indicating the associated % contents. e.g. X2CrNi18-9 designates a stainless steel whose average contents in carbon, Chromium and Nickel are about 0,02%, 18% and 9% respectively.

BS EN 10027-2:1992 Designation systems for steels. Steel numbers

The other system is a numerical system. The steel numbers consist of 1 followed by a point and 4 figures. As an example the steel numbers of the above-mentioned steels are 1,8836 and 1,4307. The steel numbers are allocated by a European Registering Office. The registering authority has been given to VDEh in Dusseldorf. Various number ranges identifying the general number trends are listed belowNote: XX numbers (01-99)are allocated sequentiallyCarbon Steels

The three parts of EN 10088 were published in October 1995.

BS EN 10088-1 Stainless Steels -Part 1 : List of Stainless Steels (not for ordering)

Part 1 is a new idea, a reference list of 83 stainless steels, giving chemical composition, various physical properties, including density and a general description of the various classes of stainless steels. It is not intended for the direct placing of orders. The intention is that the steels required in the various steel product standards and application standards shall be selected from this list, as far as possible. They should not be defined slightly differently unintentionally, nor without a technical reason for different chemistry. Eventually the list in part 1 will be expanded to include corrosion resistant, hot oxidation resistant and creep resistant stainless steels, for general and pressure vessel use, with a cross-reference matrix showing which steels are in which standards, including the main application standards. At the moment there are frequent additions to this information.

BS EN 10088-2 Stainless Steels Part 2: Technical Delivery conditions for sheet/plate and strip for general purposes

This part of EN 10088 gives the properties and other delivery conditions for flat products for general purposes, i.e. not



for pressure vessels nor for aerospace or other specialised applications, such as springs, It is used for ordering purposes. It contains 68 steels, more than BS1449-2 which it largely replaces.

It is based on a steel naming and numbering system, developed from the German Werkstoff system, which was the most suitable system available at the time the first EN standards were created.

Steel grades are classed as 'standard' or 'special' depending on how widely available they are, and how wide is their scope of application. 'Special' grades are likely to be more difficult to obtain, although the technical requirements are not different in kind between the two classes. There should be at least one grade listed, suitable for each general application. Mechanical properties are significantly more demanding than in BS 1449:2 but quite attainable in practice, with generally higher strength values, demonstrating the very useful properties of stainless steels.

Proof stress values at elevated temperatures are included and properties in the work hardened condition.
