PHSS Alloy
Precipitation Hardening Stainless Steel Alloy

AMD Corp. is currently offering the production technologies and US patents of PHSS alloy for sale or licensing.

High strength precipitation hardening stainless steel alloy (“PHSS alloy”) is a new material for the high-stressed aerospace and turbomachinery components. Two grades of PHSS alloy possess the most attractive properties for industrial applications.
Grade1 is a material for the high-stressed aerospace landing gears and structural components.
Table 1 shows a comparison of mechanical properties of Grade1 and the commercial Custom 465 alloy (Carpenter Technology Corp.) after aging at 900-950F.
Table 1

Grade1 has showed no rust after the salt spray per ASTM B-117 in 5% NaCl solution at 95°F for more than 200 hrs.
Cost of production of Grade1 is similar to the cost of production of Custom 465, while the cost of raw materials is ~10% higher than the cost of Custom 465.

Grade2 is a material for high-stressed gas turbine components such as impellers, discs, and shafts.
Table2 shows a comparison of mechanical properties of Grade2 after aging at 1400-1450F and the commercial A286 alloy after aging at 1350-1400F.
Table 2

Grade2 possesses excellent corrosion resistance at up to 1400F and oxidation resistance at up to 1500F. Cost of production of Grade2 is similar to the cost of A286 alloy.
Grade2 possesses excellent corrosion resistance at up to 1400F and oxidation resistance at up to 1500F. Cost of production of Grade2 is similar to the cost of A286 alloy.

Grade1 and Grade2 can be produced by vacuum melting of ingots followed by hot working or by Hot Isostatic Pressing (“HIP”) or Additive Manufacturing (“AM”) of powders.
