Material Description

Material Number	Material Name	Material Number (single)	Standard	Scope	Standard Status	Country	Predecessor	VDA 231-106 classification
1.7225 (DIN EN ISO 683-2 : 2018-09)	42CrMo4	1.7225	DIN EN ISO 683-2 : 2018-09	Supersedes DIN EN 10083-3 : 2007-01	Valid	Germany	42CrMo4	1.1.1	1)
1) Remark: Steel 42CrMo4 is applicable for high loaded parts (also large forged parts) with high wear resistance and very favorable core properties in vehicle manufacturing, engine and machine engineering (e.g. crankshafts, pinions, balancer shafts). The steel shows high resistivity to static and dynamic loading.
