Duplex 2205 stainless steel exhibits excellent corrosion resistance, much higher than that of grade 316. It resists localized corrosion types like intergranular, crevice and pitting. Ductility of Duplex 2205 is lesser than austenitic grades; therefore, cold heading is not possible on this grade. In order to carry out cold heading operations on this grade, intermediate annealing should be carried out. All Duplex 2205 Seamless Pipe produced according to the ASTM A789 must be furnished in a heat treated condition. This heat treatment performed on the Duplex 2205 Pipe must be keeping with accordance to the specified temperature and quench conditions.
