EN 10269 Grade X2CrNiMo17-13-3 / 1.4429
This European Standard specifies requirements for semi-finished products, bars and rods for fasteners with
properties specified at elevated and/or low temperatures made of non-alloy and alloy (including stainless)
steels and nickel alloys as given in Table 1.
The requirements of this standard may be applied also to the finished fasteners.
The general technical delivery conditions in EN 10021 also apply to products supplied in accordance with this
European Standard.
