Abstract Stainless steels contribute properties and characteristics which are otherwise unavailable within the alloy systems of the various ferrous alloy groups. Austenitic stainless steels are the most widely produced stainless steel and are used considerably at elevated temperatures. Type 304 (sometimes referred to as 18-8 stainless) is the most widely used alloy of the austenitic group. It has a nominal composition of 18% chromium and 8% nickel, the addition of molybdenum to an essentially Type 304 base, produced by Types 316.The addition of titanium to an essentially Type 304 base, produced by Types 321. These three different types of austenitic stainless steels, 304L, 316Ti and 321, (suffix L:10w carbon content and suffix Ti: titanium stabilized), have been investigated in this scientific report via welding processes to check weldability of these materials by two different methods (SMA Wand GT A W), and also via the corrosion test applied on each type by immersing samples of these materials into the Hydrochloric acid fuming 37% and weighing the difference in their weights at specific periods under ambient conditions. |
