E460 DD Chemical Element Composition Content (%)

Component	C	Si	Mn ^②	P	S	Cr	Ni	Cu ^④	Mo	Ti ^③	V ^③	Nb ^③	Al ^③
Minimum Value	-	-	1	-	-	-	-	-	-	0.02	0.02	0.015	0.02
Maximum Value	0.2	0.5	1.7	0.03	0.03	0.7	1	0.7	0.4	0.2	0.2	0.06	-

① As the chemical composition influences the welding characteristics, if the purchaser so requests, the manufacturer shall, at the time of the order being placed, indicate the type of steel which he will supply and the maximum values or the range of the alloying elements which will be used in that steel.
② For products of thickness 6 mm or under, the manganese content may be reduced by 0.2 % (m/m).
③ The steels shall contain, in the percentage indicated in the Table, at least one of the grain-refining elements. If these elements are used in combination, the content for at least one of them shall be not less than the specified minimum value.
④ By agreement at the time of ordering, the maximum copper content may be 0.30 %(m/m).
⑤ Ceq=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15
