Steel used in the automotive industry for the production of heavily loaded parts: gears, crankshafts, axles, etc.
grades of the steel can be used also for parts operating at higher temperatures and for parts working at very low temperatures.
40H2MF grade is provided as round-rolled bars, forgings, round bars, square bars, flat bars.
