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 10088-2:2014 Edition

BS EN 10088-2 was originally published in 1995. The second current version, BS EN 10088-2:2005, has been superseded by BS EN 10088-2:2014. The tables shown here only have the 2014 tensile and where appropriate, hardness, property ranges of the martensitic steels. No new grades were added. The properties for 1.4034 were amended.

Note

  1. C= Cold rolled strip; H= hot rolled strip; P= hot rolled plate.
  2. A= annealed, QT= quenched and tempered.
  3. 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.
  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 annealed condition; in such cases the mechanical properties are to be agreed at the time of enquiry and order.
