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.

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 The second, current version, EN 10088-2:2005, has superseded EN 10088-2:1995, which was withdrawn by BSi on 20th June 2005.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 and where appropriate, hardness, properties ranges of the martensitic steel. Three new standard, 420 1.4024 1.4419 and 1.4110 and two new special 1.4422 and 1.4423 martensitic grades 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

Grade 1.4021 has had tensile maxima added for cold rolled strip products. Grades 1.4313 and 1.4418 have had changes made to the specified proof strengths. In addition the elongation minimum for 1.4313 and the tensile range for 1.4418 have been changed.

1. C= Cold rolled strip; H= hot rolled strip; P= hot rolled plate.
2. A= annealing, QT= quenching and tempering.
3. The Brinell or Vickers or Rockwell hardness is normally determined for product forms C and H in heat-treatment condition A. The tensile strength test shall be carried out in referee testing.
4. 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.
5. The values apply for test pieces with a gauge length of 5.65 So0.5
6. Plates may also be delivered in the annealing condition; in such cases the mechanical properties are to be agreed at the time of enquiry and order.
