Nitrogen Strengthened XM-19 UNS S20910 Stainless Steel Round Bars
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.
XM-19 stainless also has very good mechanical properties at both sub-zero and moderately elevated temperatures.
XM-19 stainless 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.
Grade XM-19 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.
