EN 10088-3 Mechanical properties austenitic stainless steel bar
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 austenitic stainless steel.
EN 10088-3 was originally published in 1995. The second, current version, EN 10088-3:2005, has superseded EN 10088-3:1995, which was withdrawn by BSi on 20th June 2005.
The tables shown here only have the 2005 tensile strength properties ranges of the austenitic steel. New grades have been added as follows:
One standard austenitic grade 1.4570 has been moved from the austenitic special category. Twelve special austenitic grades 1.4319, 1.4325, 1.4315, 1.4466, 1.4652, 1.4369, 1.4372, 1.4374, 1.4597,1.4598, 1.4659, 1.4565
The mechanical properties of the 1995 grades were changed for grade 304L 1.4307. This article is specfically for bright products which were introduced in the 2005 edition.
The austenitic steel 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.

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
