Introduc tionIntroduc tionIntroduc tionIntroduc tion

Since 1988 a new series of 'mandatory' European standards (EN = Europaischen Normen) has been created, to replace nationalstandards, 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 betweencountries. The national standards bodies, of which BSI is one, are required to officially withdraw their national standards, when an ENis 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 thisdocument from other standards. For example, tensile testing methods are standardised in a different document to material propertyvalues, and dimensional tolerances in other separate standards. Thus, changed requirements need only to be written into onedocument.

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 fullyaccept and understand European Standards, will it actually happen.

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

This is a steel material designation system based on names. These names consist of alpha numerical characters and define two maingroups of 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)BS EN 10088-1 Stainless Steels -Part 1 : List of Stainless Steels (not for ordering)BS EN 10088-1 Stainless Steels -Part 1 : List of Stainless Steels (not for ordering)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 densityand a general description of the various classes of stainless steels. It is not intended for the direct placing of orders. The intention isthat the steels required in the various steel product standards and application standards shall be selected from this list, as far aspossible. 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 mainapplication standards. At the moment there are frequent additions to this information.

This part of EN 10088 gives the properties and other delivery conditions for flat products for general purposes, i.e. not for pressurevessels 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 suitablesystem 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 ofapplication. '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 aresignificantly more demanding than in BS 1449:2 but quite attainable in practice, with generally higher strength values, demonstratingthe very useful properties of stainless steels.

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

Note: Steel products are defined in BS EN 10079:1992These standards cover bright steel bars in drawing, turned or ground conditions. They do not cover cold rolled products and cutlengths from strip or sheet produced by cutting

Part 1 ..General



Drawn products:These are products of various cross section shapes which are obtained after descaling, by drawing of hot rolled bar or rod on a drawbench. This involves cold deformation without removing material. This operation gives the product special features with respect toshape, dimensional accuracy (BS ISO 286 IT11 or better) and surface finish. This process results in cold working on the material.

Turned productsRound bar produced by turning on a lathe of Cold Drawn steel (Turning Hot rolled steel is not part of this standard). The turningremoves surface defects and carburisation.

Ground / Polished BarCold Drawn and/ or Turned bar is ground or polished to improve the surface quality and dimensional accuracy.

This steel is classified in accordance with BS EN 10020 and identified in accordance with the relevant Standard BS EN 10277 parts 2-5.The steel designation is in accordance with BS EN 10027 -1 and the number is in accordance with BS EN 10027-2

In accordance with this standard the primary information to be supplied by the purchases includes the following...

a) The quantity to be delivered (mass/ number of bars) . e.g. 2tb) The product shape (round, square, hexagon, flat ) e.g. round c) The dimensional Standard e.g BS EN 10278 d) The dimensions and tolerances e.g 20mm dia , tolerance h9, stock length 6 000mme) Reference to European Standard e.g BS EN 10277-3f) Steel name -in accordance with BS EN 10027-1 (chemical composition) or number in accordance with BS EN 10027-2. e.g.38SMn28 (1.0760) (0.38% Carbon, 0,28% Sulphur - average %'s) or 1.7021g) Delivery condition e.g +C h) Class of surface quality e.g class 3

Optional information which may be provided includes,reference testing for products used in the quenched and tempered condition (see B.1); any fine grain requirement and verificationrequirement for the verification of non-metallic inclusions: depth of decarburization additional requirements to the tolerances on shape according to EN 10278: temporary corrosion protection : non-destructive testing : product analysis : special marking : hardenability requirements for grades of EN 10277-4 and EN 10277-5 and EN 10277-5); type of inspection document in accordance with EN 10204 (see 8.1).

Details of these optional features are provided in the Standard.
