Ambient temperature mechanical properties of martensitic 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% 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.
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 10088-2:2005 Edition
BS EN 10088-2 was originally published in 1995. The second, current version, BS EN 10088-2:2005, has superseded BS EN 10088-2:1995, which was withdrawn by BSi on 20th June 2005.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, property ranges of the martensitic steels. Three new standard, 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.

Note
- C= Cold rolled strip; H= hot rolled strip; P= hot rolled plate.
- A= annealed, QT= quenched and tempered.
- The Brinell or Vickers or Rockwell hardness is normally determined for product forms C and H in heat-treatment condition A. The tensile test shall be carried out in referee testing.
- 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
- Plates may also be delivered in the annealed condition; in such cases the mechanical properties are to be agreed at the time of enquiry and order.
