EN 10028-3 P460NL1 steel and P460NL2 steel comparison

EN 10028-3 P460NL1 steel and P460NL2 steel have much in common, including P460NL1 P460NL2 steel chemical composition and mechanical properties. Their main difference lay in impact energy. Below is detailed analysis for you.

1)EN 10028-3 P460NL1 steel and P460NL2 steel chemical composition

EN 10028-3 steel Grade	C	Si	Mn	P	S	Altotal a	N	Cr	Cu b	Mo	Nb	Ni	Ti	V	Nb+Ti+V
P460NL1 steel	0.2	0.6	1.10-1.70	0.025	0.015	0.020 min	0.025	0.3	0.7	0.1	0.05	0.8	0.03	0.2	0.22
P460NL2 steel	0.2	0.6	1.10-1.70	0.02	0.01	0.020 min	0.025	0.3	0.7	0.1	0.05	0.8	0.03	0.2	0.22

The Al content may fall short of this minimum if Nb, Ti, or V are additionally used for Nitrogen binding. If only Al is used for Nitrogen binding, the ratio Al/N shall be 2 or greater.

If Cu exceeds 0.30%, Ni shall be at least half of the Cu content.

We can find that EN 10028-3 P460NL1 steel and P460NL2 steel chemical composition are almost same. The very small difference is that P460NL2 steel control more strictly for Phosphorus and Sulfur.
