BS EN is the material standard for stainless steel sheet, plate and strip for general purposes. 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 was originally published in The tables shown here only have the composition ranges. There have been 14 new grades added compared to the edition and the compositions of 3 grades have been changed including 2 austenitic grades 1.
The new grades added include austenitic grades 1. 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. A single check sample on cast with a declared analysis of say, Contact Members Area. Toggle navigation.

It is important to carefully check the standard in cases of dispute.
Stainless Steel Grades
The chromium reacts with air to form a light, invisible oxide covering which protects from further corrosion. If the covering is damaged, further corrosion takes place thus maintaining the film. The position is further complicated by the fact that steel for different purposes has different standards and different ways of specifying. The following is a guide to the various standards and the situation generally with regard to the use of stainless steel. The common grades used for fittings are listed below, together with the various ways of specifying them, which may be found in specifications and literature -. BS - Wrought steels for mechanical and allied engineering purposes Part General inspection and testing procedures and specific requirements for carbon, carbon manganese, alloy and stainless steels. BS - Steel plate, sheet and strip Part Specification for stainless and heat resisting steel plate, sheet and strip.
