Ambient temperature mechanical properties of ferritic stainless steel flat products to BS EN 10088-2

BS EN 10088-2 is the material standard for stainless steel sheet, plate and strip for general purposes. This article gives the 0.2% and 1.0% proof strength, tensile strength and elongation of the 26 ferritic grades specified. The standard also specifies the resistance to intergranular corrosion acceptance criteria. For reasons of space, these are omitted from the tables shown here.

Ambient temperature mechanical properties of austenitic-ferritic (duplex) stainless steel flat products to BS EN 10088-2

BS EN 10088-2 is the material standard for stainless steel sheet, plate and strip for general purposes. This article gives the 0.2% and 1.0% proof strength, tensile strength and elongation of the 12 austenitic-ferritic (duplex) grades specified. The standard also specifies includes impact properties and resistance to intergranular corrosion acceptance criteria. For reasons of space, these are omitted from the tables shown here.

Ambient temperature mechanical properties of martensitic stainless steel flat products to BS EN 10088-2

BS EN 10088-2 is the material standard for stainless steel sheet, plate and strip for general purposes. This article gives the 0.2% proof strength, tensile strength, elongation and hardness levels, where specified, of the 14 martensitic grades listed in the standard. The standard also specifies includes impact properties fro some grades. For reasons of space, these are omitted from the tables shown here.

Tolerances - Proposed New Standards for Stainless Steel Flat Products

There has been an attempt to produce worldwide standards for stainless steel flat products by ISO this has resulted in the following situation:

Ambient temperature mechanical properties of austenitic stainless steel flat products to BS EN 10088-2

BS EN 10088-2 is the material standard for stainless steel sheet, plate and strip for general purposes. This article gives the 0.2% and 1.0% proof strength, tensile strength and elongation of the 44 austenitic grades specified. The standard also specifies includes impact properties and resistance to intergranular corrosion acceptance criteria. For reasons of space, these are omitted from the tables shown here.

Product Analysis Tolerances for Steels to EN 10088-2 and EN 10088-3

Permissible product analysis tolerances on the cast analysis ranges given in EN 10088-2

Tolerances to BS EN 10258 for cold rolled narrow stainless steel strip

EN 10258 applies only to: Cold rolled narrow strip which is defined as having a rolled width of < 600 mm Coils slit from such narrow strip Cut lengths obtained from cold rolled narrow strip Maximum thickness of 3.00 mm A range of special tolerances are provided for on thickness, width, length, flatness and edge camber.

Chemical composition of heat resisting steels to BS EN 10095

BS EN 10095 is the material standard for heat resisting steels and nickel alloys. The chemical composition of the common grades of stainless steel covered in the standard are listed. Ferritic, austenitic and austenitic-ferritic (duplex) grades are included.

Chemical composition of stainless steel flat products for pressure purposes to BS EN 10028-7

BS EN 10028-7 is the material standard for stainless steel sheet, plate and strip for pressure purposes.  The chemical compositions of these stainless steels are shown in this article.

Chemical composition of stainless steels to BS 1449-2

BS 1449-2 Specification for stainless and heat-resisting steel plate, sheet and strip was last published in 1983. It covered flat products in both annealed and temper (cold) rolled supply conditions.

Tolerances to ISO 9444 Part 2 for continuously rolled wide hot rolled strip, plate/sheet and cut lengths

This standard covers continuously rolled hot rolled flat products of rolled widths > 600 mm in stainless steels. It therefore is designed to replace EN 10051. The maximum width is increased to 2500 mm compared to EN 10051.

Tolerances to ISO 18286 for hot rolled stainless steel quarto plates

This standard covers hot rolled stainless steel plates rolled on a reversing mill known as quarto plate. It may also be taken to cover plate rolled on a Steckel mill but taken out of the process before coiling has begun.

Tolerances to BS EN 10058 for hot rolled flat 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 EN 10051 for continuously rolled hot rolled plate sheet and strip

This standard covers continuously rolled hot rolled flat products with a rolled width of 600 - 2200mm inclusive in non-alloy, alloy and stainless steels. Strip of width < 600mm slit from wide strip is therefore covered by the standard.

Tolerances to BS EN 10259 for cold rolled wide stainless steel strip

Preferred thicknesses are shown and are intended to indicate which gauges are more likely to be available on an ex-stock basis from suppliers. Buyers of other thicknesses may be required to purchase full coil weight quantities.

Tolerances to ISO 9445 for cold rolled narrow and wide strip, plate/sheet and cut lengths

This standard is designed to bring together tolerances for cold rolled narrow and wide strip. It has officially superseded EN 10258 and EN 10259 although of course customers and suppliers are entitled to continue to use these standards. In most respects the tolerances from these standards are identical to the ones in this new ISO standard. The major differences are: Additional table for wide strip is included which is based on Japanese practice. Slightly different edge camber tolerances than in EN 10259 for wide strip. Provision for width tolerance on wide strip with mill edges.

Chemical composition of stainless steel flat products for general purposes to BS EN 10088-2

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.

Tolerances to EN 10029 for hot rolled plate 3mm and above

This standard covers a wider group of steels than just stainless: Non-alloy and alloy steels including stainless steels with: Nominal thickness > 3mm < 250mm Nominal width > 600mm Specified minimum yield strength < 700 N/mm2 Tolerances on plate less than 600 mm wide shall be agreed at time of enquiry/order
