EN 16Mo3 equivalent grade DIN 15Mo3

Though 16Mo3 steel and 15Mo3 steel have much in common even in names, they are two materials under different technical standards. 16Mo3 steel standard is EN10028-2, and 15Mo3 steel standard is DIN17155. DIN 15Mo3 is EN 16Mo3 equivalent grade.

16Mo3 steel and EN 16Mo3 equivalent grade DIN 15Mo3 chemical composition:

Grade	C	Si	Mn	P	S	Cr	Cu	Mo	Ni	N
15Mo3	0.12-0.20	0.10-0.35	0.40-0.90	≦0.035	≦0.030	≦0.25	≦0.30		≦0.30
16Mo3	0.12-0.20	≦0.35	0.40-0.90	≦0.025	≦0.010	≦0.30	≦0.30	0.25-0.35	≦0.30	≦0.012

16Mo3 steel and EN 16Mo3 equivalent grade DIN 15Mo3 mechanical properties:

Grade	Yield Strength	Tensile Strength	Elongation
Grade	(Mpa)	(MPa)	(%)
15Mo3	≧275	440-590	≧20
16Mo3	≧275	440-590	≧22

It is easy to note that the chemical composition and mechanical properties of 16Mo3 steel and EN 16Mo3 equivalent grade DIN 15Mo3 are almost the same. They are perfectly equivalent to each other.
