Chemical compositions of stainless steels to BS EN 10297-2

BS EN 10297-2 is the material standard for stainless and heat-resisting steels for seamless tubes for mechanical and general engineering, (i.e. not pressure), purposes. This new standard was first published in December 2005. It does not replace any previous British Standards, unlike the counterpart welded tube standard BSEN 10296-2, which replaced BS 6323-8:1982.

Chemical compositions of stainless steels to BS 6323-8

BS 6323 consisted of 8 parts. Only part 8 covered longitudinally welded stainless steel tubes for automobile, mechanical and general engineering purposes. This part of the standard was last published in 1982. Seamless stainless steel tubes were not covered by BS 6323.

Ambient temperature mechanical properties of austenitic stainless steel long products to BS EN 10088-3

BS EN 10088-3 gives the mechanical properties for stainless steel semi-finished products, bars, rods and sections for general purposes. The properties given in this article are proof strength, tensile strength, elongation and hardness of austenitic stainless steels.

Mechanical properties for stainless steels to BS EN 10217-7

BS EN 10217-7 2005 is the material standard for stainless steels for welded tubes for pressure purposes. This new standard was first published in February 2005.

Chemical compositions of stainless steels to BS EN 10296-2

BS EN 10296-2 is the material standard for stainless and heat-resisting steels for circular welded tubes for mechanical and general engineering, (i.e. not pressure), purposes. This new standard was first published in December 2005 and replaces BS 6323-8:1982, which is now withdrawn.

Chemical compositions of stainless steels to BS EN 10217-7

BS EN 10217-7 2014 is the latest revision for stainless steels for welded tubes for pressure purposes. The standard was first published in 2005. The latest revision has not added any new grades. Some anomalies have been corrected. Nickel and chromium contents are now quoted to 1dp compared to 2dp. The nickel content for grade 1.4307 is now harmonised at 8.0/10.5 in line with other standards. It had been 8.00/10.00 in the 2005 version.

Chemical compositions of stainless steels to EN 10216-5

BS EN 10216-5 2004 is the European Standard for Stainless Steel Seamless Tubes for pressure purposes. It covers the following categories:

Elevated and sub-zero temperature mechanical properties of stainless steels to BS EN 10272

BS EN 10272 is the material standard for stainless steel bars for pressure purposes. Most of the steels in BS EN 10272 have the same chemical compositions as bar grades specified in BS EN 10088-3, which also specifies the ambient temperature mechanical properties for the bars. The exception is grade 1.4951 which was added in the 2007 edition of the standard. Except for this grade, only the specified elevated and sub-zero temperature mechanical properties are covered in this article.

Tolerances to BS EN 10061 for hot rolled hexagon stainless steel bars

Tolerances for hot rolled stainless steel bars are included with the general standards for hot rolled steel bars. The various sections are covered by:- BS EN 10058 - Flat bars BS EN 10059 - Square bars BS EN 10060 - Round bars BS EN 10061 - Hexagon bars

Tolerances to BS EN 10297-2 for seamless stainless steel tubes

Unlike the standards for flat and long products, the standards for stainless steel tube products contain information on tolerances. This is possibly because the tolerance requirements for tubes are simpler to define.

Tolerances to BS EN 10059 for hot rolled square stainless steel bars

Tolerances to BS EN 10296-2 for welded stainless steel tube

Chemical composition of stainless steel long products for general purposes to BS EN 10088-3

BS EN 10088-3 is the material standard for stainless steel semi-finished products, bars, rods and sections for general purposes. Ferritic, martensitic, precipitation hardening, austenitic and austenitic-ferritic, (duplex), grades are included. The chemical composition of all the grades of stainless steel

Tolerances to BS EN 10060 for hot rolled round stainless steel bars

Tolerances to BS EN 10278 for bright stainless steel bars

Tolerances for bright drawn, ground, turned and polished stainless steel bars are included with the general standards for other bright steel bars in BS EN 10278.
