EN 10269 Grade C45E / 1.1191
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.
