reduce Two Percentage points.
2 For normal thickness 5/*6in(8mm), the deduction from the
specified percentage of elongation in 8 in(**0mm).
shall be made for decereses of the nominal thickness below 5/*6
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,*5 % Ni, 0,*0 % Mo and 0,*5
% Zr.
2) Exceeding the specified maximum value is permitted if the
phosphorous content remains below the maximum value by 0,**5 % for
each 0,**1 % of nitrogen; however, the nitrogen content must not
exceed 0,**2 % in the heat analysis.
3) The maximum nitrogen content shall not apply if the steel grades
contain at least 0,**0 % Altotal or sufficient quantities of other
nitrogen-fixing elements.
4) The steel grades contain at least one of the following elements:
Altotal : ≥ 0,**0 %, Nb: 0,**5 - 0,**0 %, V: 0,*2 - 0,*2 %, Ti:
0,*2 - 0,*0 %. If a combination of these elements is present, at
least one of them is contained with the specified minimum
content.
