Remarks:
1 For plates wider than24 in(600mm), the Elongatior requirment is reduce Two Percentage points.
2 For normal thickness 5/16in(8mm), the deduction from the specified percentage of elongation in 8 in(200mm). shall be made for decereses of the nominal thickness below 5/16 in.(8mm).
see elongation requirement adjustment under the tension tests section of specification A6 for deduction values.

1) The steel may contain a maximum of 0,65 % Ni, 0,30 % Mo and 0,15 % Zr.
2) Exceeding the specified maximum value is permitted if the phosphorous content remains below the maximum value by 0,005 % for each 0,001 % of nitrogen; however, the nitrogen content must not
exceed 0,012 % in the heat analysis.
3) The maximum nitrogen content shall not apply if the steel grades contain at least 0,020 % Altotal or
sufficient quantities of other nitrogen-fixing elements.
4) The steel grades contain at least one of the following elements: Altotal : ≥ 0,020 %, Nb: 0,015 - 0,060 %,
V: 0,02 - 0,12 %, Ti: 0,02 - 0,10 %. If a combination of these elements is present,
at least one of them is contained with the specified minimum content.
