1) Elements not listed in this table shall not be intentionally added to the steel without the customer's consent, except in the final processing of the smelting.
2) For product thickness < 6mm, a minimum Mn content of 0.60 is permitted
3) Altotal content may undercut this minimum if niobium, titanium or vanadium is used additionally for nitrogen fixation.
4) If only aluminium is used for nitrogen fixation, an Al/N ratio ≥ 2 must be used.
5) The sum of the weight percentages of the three elements chromium, copper and molybdenum shall not exceed 0,45 %.
6) If the weight percentage of copper exceeds 0,30 %, the weight percentage of nickel shall be at least half the weight percentage of copper.
7) P420NH, P420NL1, P420NL2 - A lower maximum copper content and/or a maximum sum of copper and tin content, e.g. Cu + 6 Sn ≤ 0,33%, may be the content of an agreement at the time of enquiry and ordering, e.g. when hot forming is taken into account (this is an optional requirement).
