Ambient temperature mechanical properties of ferritic 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. This article covers ferritic stainless steels supplied as bright bars 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 10088-3:2014 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 The second version, BS EN 10088-3:2014, has been superseded by BS EN 10088-3:2014.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 ferritic steels. Three new ferritic grades 1.4611, 1.4621, and 1.4613 have been added. However, none of these grades have any properties defined for bright bar.
This article covers bright products.

Note
- Width across flats for hexagons.
- 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
- In the range 1mm<t<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
The ferritic steels are in the annealed condition. The annealing treatment may be omitted, if the conditions for hot working and subsequent cooling are such that the requirements for the mechanical properties of the product and the resistance to intergranular corrosion as defined in EN ISO 3651-2 are obtained.
