42CrMoS4 is steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening. The surface hardness will exceed min. 53 HRC. 42CrMoS4 can be delivered M-treated in order to optimize the machinability

SUPPLEMENTAL MELTING PRACTICE: The following supplemental melting practices apply to this specification if referenced by the appropriate supplemental number in the table at the end of this specification.
The steel shall be melted by basic oxygen (BOF) or basic electric furnaces (EF). Steel melted in acid furnaces shall not be permitted for the manufacturing of this material. Material processed by vacuum induction melting (VIM) or which receives additional processing by vacuum degassing (VD), argon-oxygen decarburization (AOD), vacuum oxygen decarburization (VOD), electroslag remelting (ESR) or vacuum arc remelting (VAR) shall also be acceptable. The steel shall be fully killed and melted to a fine grain practice.
The steel shall be melted by electric furnace (EF) with subsequent vacuum degassing (VD), argon-oxygen ecarburization (AOD), vacuum oxygen decarburization (VOD), or may be melted by vacuum induction melting (VIM). At the producer soption , additional processing by vacuum arc remelting VAR) or electroslag remelting (ESR) may also be used.
Sulfide shape control by calcium or rare earth injection may also be used.
The melt practice shall be reported on the Certified Test Report.
The minimum forging reduction ratio of 42CrMoS4 forged bars shall be 4:1, where the forging reduction ratio is defined as the product the area reduction ratio(s) for each hot working operation performed
