Ambient temperature mechanical properties of martensitic and precipitation hardening stainless steel bright bars to BS EN 10088-3

Introduction

BS EN 10088-3 gives the mechanical properties for stainless steel semi-finished products, bars, rods and sections for general purposes. The properties given in this article are proof strength, tensile strength, elongation and hardness of martensitic and precipitation hardening stainless steels.

The data given is not intended to replace that shown in individual standards to which reference should always be made.

BS EN 10088-3:2014 Edition

BS EN 10088-3 was originally published in 1995. The second  version, BS EN 10088-3:2014, has been superseded by BS EN 10088-3:2014.

The tables shown here only have the 2014 tensile property ranges of the martensitic and precipitation hardening steels. Two new grades were added:

1.4150, 1.4612 (Neither grade has properties defined for bright bar).

There were changes to the mechanical properties for bright bar for the following grades;

1.4028, 1.4122, 1.4057.

This article is specfically for bright products.

Note

  1. Width across flats for hexagons.
  2. For information only.
  3. Elongation is valid only for dimensions of 5mm and above. For smaller diameters, the minimum elongation has to agreed upon at the time of the enquiry and order
  4. In the range 1mm<<5mm valid only for rounds. The mechanical properties of non round bars with thicknesses < 5mm have to be agreed at the time of the enquiry and order
