BS 2S143, FV520B:chemical composition, application and machinability. Precipitation Hardening Stainless Steel. British aerospace grade as bar and forgings (FIRTH VICKERS FV520B:Hardenable stainless steel, a Martensitic stainless steel). High strength with moderate/good corrosion resistance. For mechanical components in aerospace and defence. Characterization of Precipitated Phases in the Weld of May 21, 2021 · The formation mechanism of the reversed austenite and the interaction between austenite inversion and plastic deformation in the G520 martensitic stainless steel welds was studied by adjusting the tempering holding time during post-weld heat treatment. The results show that the weld microstructure has consisted mainly of tempered lath martensite, reversed austenite, and grain
