Objetivo
Nitrogen is today a common alloying element in stainless steels, which has both technological and economic advantages. Nitrogen alloyed duplex stainless steels present improved corrosion resistance increased strength and improved structural stability. However, during welding, micro-structural transformations and nitrogen loss from the weld pool can lead to reduction in corrosion resistance and strength. The objectives of the research are: understanding the role of the different micro-structural parameters in the reduction of corrosion resistance of high nitrogen stainless steels and increasing the reliability of welding of such steels by improving welding procedures and thereby avoiding nitrogen losses or excessive nitrogen uptake and porosity.
