ATI 50™ / ATI XM-19™ alloy is a nitrogen-strengthened austenitic stainless steel with corrosion resistance superior to Types 316 and 317 austenitic stainless in combination with significantly higher strength. ATI 50 alloy also has very good mechanical properties at both sub-zero and moderately elevated temperatures.

The alloy can be fabricated and welded by the conventional equipment and procedures employed for austenitic stainless steel. It is non-magnetic as annealed and after severe cold work.

ATI 50 alloy has an excellent combination of corrosion resistance and strength for application in heat exchanger parts, pumps, spent nuclear fuel containers, flood control barriers, pulp and paper, food processing, petrochemical, fertilizer, structural components, and other similar equipment.
