General for 42CrMo4 hollow steel
42CrMo4 is a steel for quenching and tempering, which has a good combination of strength and
toughness in the quenched and tempered condition. After oil quenching it will be through hardened
up toØ60 mm bar diameter. The micro structure of bigger dimensions is not fully martensite. The
steel is applicable to induction hardening. The surface hardness will exceed min. 53 HRC. 42CrMo4
can be delivered M-treated in order to optimise the machinabilty.
Standard
This product specification is based on EN 10083-3:2006 and the steel will meet the requirements of
this standard.
The steel pipes can also be delivered according to following European Standards:
▪ EN 10250-3 Open die steel forgings for general engineering purposes. Part 3: Special alloy steels
▪ EN 10263-4 Steel rod, bars and wire for cold heading and cold extrusion
▪ EN 10269 Steels for fasteners with specified elevated and/or low temperatures properties
▪ EN 10277-5 Bright steel products. Steels for quenching and tempering
▪ EN 10297 Seamless circular steel tubes for mechanical and general engineering purposes
▪ EN 10305 Seamless cold drawn tubes for precision applications
▪ prEN 10343 Steels for quenching and tempering for construction purposes
