(d) The Pitting Resistance Equivalent Number (PREN) is given by PREN = Cr + 3.3 X M + 16 x N, where Cr is chromium in percentage; M is molybdenum in percentage and N is nitrogen in percentage. Calculate the PREN of the duplex stainless steel (21 % Cr; 3.5 % M and 0.22 %N) and decide if this steel has sufficient seawater corrosion resistance.
