Austenitic stainless steel welds with different ferrite contents (4 and 12FN) were obtained by the Submerged Arc Welding (SAW) strip cladding process, and some clads were remelted by TIG.The welds were post weld heat treated (PWHT) at 600,800,1000"C for 1 h. Pitting potentials were measured in 1 N H
## Abstract A sulfuric acid plant was equipped with heat exchangers with Nicrofer 3620 tubing. The cooling medium was sea water. Within 5 weeks after startβup some of the tubes failed by pitting, showing that it is impossible to use stainless steel as a heat transfer material in sea water unless th
