In cost, corrosion resistance, and weldability they are one of the most suitable steels for most of today’s applications. Understanding how these grades of steel are affected by welding should be considered necessary knowledge for all welding engineers. In this study, I tried to discover how improper welding practices can adversely affect the weld content and microstructure, by using visual inspection and a microscope. Background Stainless steels are widely used in various industries where corrosion is concern. The welding of stainless steels, especially the austenitic grades, is particularly important in energy-related systems. 304 stainless steel is classified as austenitic grade stainless steel. Austenitic grades contain 15% to 26% chromium and 6% to 22% nickel content required to maintain a stable austenitic structure, over the temperature range of 1100C to room temperature, without the formation of martensite. The formation of martensite is detrimental to the structure of austenitic stainless steels. It has adverse affects on the strength and toughness of this classification of steels.
