NOTE For details on delivery conditions refer back to 7.3.1.

a For product chemical composition variations see Table 12.

b The total aluminium to nitrogen ratio shall be a minimum of 2:1. When other nitrogen binding elements are used, the minimum Al value and Al:N ratio does not apply.

c The levels of the residual elements arsenic, antimony, tin, lead, bismuth and calcium shall not exceed 0,03% As, 0,010% Sb, 0,020% Sn, 0,010% Pb, 0.010%

Bi and 0,005% Ca. Boron (B) shall not exceed 0,000 5%. These elements shall be checked at least once every 5 000 tonnes at each manufacturing location and shall

be reported as a ladle analysis.

d For thickness greater than 75mm, maximum Mo content of 0,20% shall apply for delivery condition M.

e See Option 30. For thickness greater than 40mm, the minimum Ni shall be 0,30%.

f A maximum carbon value of 0,15% is permitted for thickness less than 15mm
