BS EN 10269 is the material standard for stainless and heat-resisting steels, a selection of low alloy steels and some nickel alloys for fasteners. The standard includes some elevated and sub-zero temperature mechanical properties and can be used for specifying fasteners for pressure purposes. Austenitic, martens tic and precipitations hardening stainless grades are included. The ambient temperature mechanical properties shown in this article include 0.2% proof strength, tensile strength, elongation, reduction in area and impact (chirpy) strength in the finally heat treated condition.
