Ambient temperature mechanical properties of martensitic and precipitation hardening stainless steel long products 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. This article covers martensitic and precipitation hardening stainless steels. The properties given are proof strength, tensile strength, elongation and hardness.

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

BS EN 10088-3:20014 Edition

BS EN 10088-3 was originally published in 1995. The second version, BS EN 10088-3:2005, has been superseded by BS EN 10088-3:2014.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 have been added, 1.4150 and 1.4612.

The mechanical properties of the following grades were changed:
1.4313, 1.4028, 1.4122, 1.4057, 1.4606.

This article does not include bright products.
