AMS 5561 is a sub-type specification of Stainless Steel 21-6-9, a high-manganese content nitrogen-strengthened austenitic alloy. Tech Steel & Materials offers AMS 5595 in plates, sheets, and strips of various thicknesses and sizes.
Parts made from AMS 5595 posses intergranular corrosion resistance, even at very high temperatures. Moreover, the alloy has good resistance to molten lead oxide corrosion and outstanding air corrosion resistance.
AMS 5595 plates, sheets, and strips also have low magnetic permeability and high strength in the annealed condition. The parts can be additionally solution strengthened, or strengthened using hot working and cold working processes.
AMS 5595 can be machined using traditional methods. However, the alloy has a high work hardening rate and requires higher forces than stainless steel alloys from the 300-series. For that reason, use slower machining speeds, positive feeds, and sufficient fluids.
All 21-6-9 specifications can be welded using shielded fusion and resistance welding. For the best results, we recommend using a fitting filler metal. Also, oxyacetylene welding is not recommended, as it might lead to carbon buildup in the weld.
Thanks to its favorable properties, AMD 5595 finds use in the aerospace industry for engine parts, but also chemical processing and pollution control equipment.
