Description of material
AIST is a Titanium stabilized austenitic stainless steel with both general corrosion resistance and very good intergranular corrosion resistance after welding processes or subjected to a slow cooling rate in service.
Applications
AIST is suitable for the fabrication of many products such as flanges, valves, bolting, pump shafts, food /beverages industry equipment, rings, storage tanks, many organic chemical and parts working in the mild to medium corrosive environments. This grade is chosen in the case of welding processes and in applications where intermittent heating up to 850 C° can happen.
