19-9 DL Stainless

UNS #K63198

19-9 DL stainless exhibits high strength and resistance to corrosion and oxidation at temperatures up to 1250°F (677°C). Like all austenitic alloys of this type, 19-9 DL cannot be strengthened by thermal treatment and is frequently used in the annealed condition. Higher properties can be achieved by hot-cold working. Specifications: AMS 5526 (Strip), AMS 5527 (Strip), AMS 5720 (Bars and Forgings), AMS 5721 (Bars and Forgings), AMS 5722 (Bars and Forgings)
