Chemical composition of stainless steel flat products for general purposes to BS EN 10088-2
Introduction
BS EN 10088-2 is the material standard for stainless steel sheet, plate and strip for general purposes. A total of 97 stainless steel grades are listed, including 25 ferritic, 14 martensitic, 2 precipitation hardening, 44 austenitic and 12 austenitic-ferritic (duplex) grades. The chemical compositions of these stainless steels are shown in this article.
As an alternative to scanning down the list try the ‘find’ facility on your keyboard, using the ‘Ctrl’ and ‘F’ keys together. Type in the term you are looking for in the dialog box that then appears.
The data given is not intended to replace that shown in individual standards to which reference should always be made.
BS EN 10088-2:2014 Edition
BS EN 10088-2 was originally published in 1995. The second version, BS EN 10088-2:2005, has now been superseded by BS EN 10088-2:2014 which was withdrawn by BSi.
The tables shown here only have the 2014 composition ranges.
There have been 14 new grades added compared with the 2005 edition and the compositions of 3 grades have been changed including 2 austenitic grades (1.4371, 1.4597) and one duplex grade (1.4362). LAST UPDATED 13th November 2014.
The new grades added include austenitic grades 1.4618, 1.4376, 1.4640, 1.4646, austenitic-ferritic (duplex) grades
1.4162, 1.4662, 1.4482, 1.4062 and ferritic grades 1.4600, 1.4607, 1.4611, 1.4613, 1.4630, 1.4634.
It is important to carefully check the standard in cases of dispute.
The permissible product analysis tolerances on values for cast analysis, shown in Table 5 of the standard are unchanged. For example, for a cast of 1.4301 grade, with a specified chromium range of 17.5 to 19.5, the tolerance on a product check sample is still + or – 0.20, not + or – 0.2 as might be expected. A single check sample on cast with a declared analysis of say, 18.1 must therefore be between 17.90 and 18.30.
See table below for full details of permitted deviations of product analysis
