1.7225 (DIN 17200 : 1987-03)	42 CrMo 4	1.7225	DIN 17200 : 1987-03	DIN 17200 : 1987-03 replaced by DIN EN 10083-1/-2 : 1991-10	Replaced	Germany	42CrMo4	1.1.1	≥ -40	1)
1) Remark: Steel 42 CrMo 4 is suitable for high loaded parts (also heavy forged parts) of high wear resistance and very favorable core qualities (e.g. crankshafts, pinions, balancer shafts) in vehicle manufacturing, engine and machine engineering. The steel has a high specific static and dynamic load resistance. Lowest application temp. -40 °C.
