EN 10088-3 Duplex Steel Long Products Mechanical Properties
EN 10088-3 show the mechanical properties of stainless steel semi-finished products, bars, rods and sections for general purposes. This covers austenitic-ferritic duplex stainless steel. The properties include proof strength, tensile strength, yield strength, elongation and hardness.
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 The second, current version, EN 10088-3:2005, has superseded EN 10088-3:1995, which was withdrawn by BSi on 20th June 2005.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-ferritic duplex steel. Two new special grades have been added: 1.4477, 1.4424
This article does not include bright products. These were introduced in the 2005 edition.

These austenitic-ferritic duplex stainless steel are in the solution-annealed condition. The solution 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.
