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

Introduction

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.

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 The second version BS EN 10088-2:2005 has been superseded BS EN 10088-2:2014.

The tables shown here only have the 2014 tensile property ranges of the austenitic steels. Four new austenitic grades, 1.4618, 1.4376, 1.4640 and 1.4646 have been added.

The only changes to tensile properties for austenitic grades is in 1.4372.

Note

  1. 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.
  2. C= Cold rolled strip; H= hot rolled strip; P= hot rolled plate.
  3. If, in the case of strip in rolling widths<300mm, longitudinal test pieces are taken, the minimum values are reduced as follow:
    1. proof strength: minus 15N/mm2
    1. elongation for constant gauge length: minus 5%
    1. elongation for proportional gauge length: minus 2%
  4. 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.
  5. 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.
  6. The values apply for test pieces with a gauge length of 5.65 So0.5
