A highly corrosion-resistant stainless steel for application to chemical cargo tankers and welding consumables for the steel were developed. The stainless steel and welding consumables were designed to exhibit good resistance to corrosion by sea water and sulfuric acid. The developed welding consumables, flux-cored wire for CO2 welding and flux and solid wire for submerged arc welding, proved that it is possible to attain welded joints that satisfy required corrosion resistance and mechanical properties, and their actual use for construction of chemical cargo tankers began in June 2004.
