Gas tungsten arc welding of Nitrogen alloyed cr mo steels

Abstract

newlineNitrogen alloyed Cr Mo steels being a special material are finding newlineincreasing applications in energy chemical petrochemical fertilizer oil gas newlinemining and transportation sectors due to their outstanding combination of newlinemechanical properties as well as corrosion oxidation and wear resistance The newlinenitrogen solubility in nitrogen alloyed steel increases with alloying elements newlinelike Mo Mn Cr V Nb Ti and decrease with alloying elements like Ni Si newlineand C One of the challenges involved in Nitrogen alloyed Cr Mo Steel newlineproduction is to obtain a fully dense component with uniform nitrogen content newlineand excellent surface properties which results in homogenous microstructure newlineand better mechanical properties newline newline
