Ph 13-8 Mo is a martensitic precipitation-hardening stainless steel that has excellent strength, high hardness, superior toughness, and good corrosion resistance. Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting. The alloy is produced by vacuum induction melting (VIM) followed by electro-slag remelting (ESR).
Why is a Hughes Aircraft specification being called out for your project involving PH 13-8 Mo Stainless Steel? In 1932 Howard Hughes founded Hughes Aircraft famous for building the H-1 Racer among other aircraft which revolutionized the Aerospace industry:
Through years of mergers and acquisitions, Hughes Aircraft sold bits and pieces of its product lines to companies like Raytheon, General Motors, Boeing (Space), and other major Aerospace corporations that are responsible for Air Traffic Control systems as well as Satellites manufacturing.
13-8 Stainless Steel is used in Aerospace components, landing gear, nuclear reactor components, petrochemical industry, injection molding equipment etc.
PH 13-8 Mo Stainless Steel in the annealed condition can be strengthened further by relatively low temperature heat treatment. Fighter Jet Metals offers PH 13-8 Mo in the Annealed, H950, H1000, H1025, H1050, H1100, and H1150 Heat Treated conditions.
