It ensures protection against corrosion, in particular for steels of Rm max. > 1 450 MPa. It may be beneficial to tensile bolts of Rm max. > 1 250 MPa. 4 Limitation of process use The contact of cadmium-plated parts with titanium, titanium alloys, fuels and fuel line shall be avoided at temperature < 150 °C.

5.3 Rm max. maximum value of the tensile strength range which is defined in the standard on the steel to be treated 6 Thickness Unless otherwise specified in the product standard or definition document, the thicknesses are:  Class A: 10 µm to 20 µm (normal thickness)  Class B: 7 µm to 14 µm (for parts with close tolerances or for bolts with a thread diameter > 3,2 mm)  Class C: 5 µm to 10 µm (for bolts with a thread diameter ≤ 3,2 mm) 7 Apparatus and materials 7.1 Vacuum enclosure The vacuum enclosure shall contain the following equipment:  a variable heating system for vaporisation of the cadmium;  a rotating device to achieve a regular coating;  a vaporising dish;  a glow system and a vacuum gauge as well as an inspection window. Furthermore, a pump system is required, allowing a vacuum of at least 6,65 × 10-3 Pa to be reached. 7.2 Deposition material The cadmium used for deposition shall be at least 99,95 % pure. The mercury content shall not exceed the m
