Ambient temperature mechanical properties of precipitation hardening stainless steel flat products to BS EN 10088-2
Introduction
BS EN 10088-2 is the material standard for stainless steel sheet, plate and strip for general purposes. This article gives the 0.2% proof strength, tensile strength and elongation levels, where specified, of the 2 precipitation hardening grades listed in the standard.
The data given is not intended to replace that shown in individual standards to which reference should always be made.
BS EN 10088-2:2014 Edition
BS EN 10088-2 was originally published in 1995. The second version, BS EN 10088-2:2005, has been superseded by BS EN 10088-2:2014.
The tables shown here have the 2014 tensile property ranges of the 2 precipitation hardening steels 1.4542 and 1.4568. The specified properties have not been changed for these grades.

Note
- C= Cold rolled strip; H= hot rolled strip; P= hot rolled plate.
- AT = solution annealed; P = precipitation hardened; SR= strength relieved.
- The values apply for test pieces with a gauge length of 80mm and a width of 20mm. Test pieces with a gauge length of 50mm and a width of 12.5mm can also be used.
- The values apply for test pieces with a gauge length of 5.65 So0.5
- Delivery condition.
- Condition of application; other precipitation hardening temperatures may be agreed.
- If ordered in the finally treated condition.
- Delivery condition for further processing; final treatment according to table A.3 of BS EN 10088-2.
- For spring-hard rolled condition see EN 10151
