EN 10088-2 Mechanical Properties of Austenitic Stainless Steel
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 40 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.
EN 10088-2 was originally published in 1995. The second, current version, EN 10088-2:2005, has superseded EN 10088-2:1995, which was withdrawn by BSi on 20th June 2005.
The tables shown here only have the 2005 tensile stregnth properties ranges of the austenitic steel. Seven new 'special' austenitic grades, 1.4315, 1.4319, 1.4369, 1.4565, 1.4597, 4652 and 1.4659 have been added.
The maximum thickness ranges for the specification of mechanical properties have been extended for strip products.
Cold rolled strip, C has been increased from 6 to 8mm max. Hot rolled strip, H has been increased from 12 to 13.5mm max
The only changes to tensile properties are increases of maximum tensile strength for grades 304L 1.4307 and 1.4306. These have been increased from 650 or 670, depending on product form, to 700 N/mm2.

Note
- The solution treatment may be omitted if the conditions for hot working and subsequent cooling are such that the requirements for the mechanical properties of the product and the resistance to intergranular corrosion as defined in EN ISO 3651-2 are obtained.
- C= Cold rolled strip; H= hot rolled strip; P= hot rolled plate.
- If, in the case of strip in rolling widths<300mm, longitudinal test pieces are taken, the minimum values are reduced as follow:
proof strength: minus 15N/mm2
elongation for constant gauge length: minus 5%
elongation for proportional gauge length: minus 2%
- For continuously hot rolled products, 20N/mm2 higher minimum values of Rp0.2 and 10N/mm2higher minimum values of Rp1.0 may be agreed at the time of enquiry and order.
- The values apply for test pieces with a gauge length of 80mm and a width of 20mm. Test pieces with a gauge length of 50mm and a width of 12.5mm can also be used.
- The values apply for test pieces with a gauge length of 5.65 So0.5
