EN10297-1 Seamless Cold-Deformed Steel Pipes 42CrMo4
Mechanical Alloy Steel Seamless Tubes 42CrMo4/AISI4140
EN10297-1 Seamless cold-deformed steel pipes 42CrMo4/42CrMo4 hollow steel bars
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
