EN8D is a carbon steel, detailed in British Standard BS970
080A42 is a medium carbon and medium tensile steel used mainly for axles, spindles, studs, automotive and general engineering components. Suitable for heat treatment where extra strength is required. It is medium high carbon steel that can be strengthened by heat treating after forming. Machinability and weldability are fair. Typical uses include machine, plow and carriage bolts, cylinder head studs, machine parts etc. It is also used for U bolts, concrete re-enforcing rods, forgings and non critical springs.
