Steel used for machine parts, engines and vehicles subjected to impact,
Which require high strength and good ductility: forged crank shafts and folding, reciprocating steam engine shafts, pumps
and hammers, screws, shafts, machine tools, gear wheels and rims, which, because of the dimensions may not be case-hardened.
45HN Steel has a very small deformations with hardening, suitable for surface hardening, for parts subjected to wear out.
45HN grade or equivalent is provided as round-rolled bars, forgings, square bars, flat bars, plates, cubes, rings, rings.
