1.7003 (DIN 1654-4 : 1989-10)	38 Cr 2	1.7003	DIN 1654-4 : 1989-10	DIN 1654-4 : 1989-10 replaced by DIN EN 10263-4 : 2002-02	Replaced	Germany	38Cr2	1.1.1	1)
1) Remark: The cold-upsettable steel 38 Cr 2 can be cold-formed with a medium rate of forming according to the usual forming methods on single-stage and multi-stage presses. It is used for screws of strength class 8.8 in the lower dimension range. The steel 38 Cr 2will be replaced with steel 35 B 2.
