16MnCr5
Steel 16MnCr5 Round Bar is an unalloyed medium carbon steel, which is also a general carbon engineering steel. 16MnCr5 is a medium strength steel with good machinability and excellent tensile properties. 16MnCr5 round steel is generally supplied in the black hot rolled or occasionally in the normalised condition, with a typical tensile strength range 570 – 700 Mpa and
Brinell hardness range 170 – 210 in either condition. It does not however respond satisfactorily to nitriding due to a lack of suitable alloying elements.
16MnCr5 round bar steel is equivalent to EN8 or 080M40. Steel 16MnCr5 bar or plate is suitable for the manufacture of parts such as gears, bolts, general-purpose axles and shafts, keys and studs.

| Elements not quoted in this table shall not be intentionally added to the steel without the agreement of the purchaser, other than for the purpose of finishing the heat. Steels with improved machinability as a result of the addition of lead or higher sulfur contents, depending on the manufacturing process up to around 0.1 % S, may be supplied on request. In this case, the upper limit of the manganese content may be increased by 0.15 % |
