Abstracts: Low carbon grade type 304(18Cr8Ni) austenitic stainless steel, alloyed with nitrogen designated as 304 L SS exhibit superior strength at ambient and high temperatures, excellent corrosion resistance to replace other expensive materials. Austenitic stainless steel gets sensitized during welding. The problem of sensitization can be overcome by decreasing the carbon content. Reducing the carbon content would cause drastic reduction in mechanical properties. The existence of such stresses have been analyzed and compared. Non-destructive techniques have been used for measuring residual stresses and defects in welding. The purpose of this review is to investigate weld ability of 304 L SS, study the beneficial effect on fully austenitic steels with particular emphasis on alloyed and stabilized stainless steels.
