Steel 09KH17N3SL (10Х17Н3СЛ)
Designation
Description
09KH17N3SL steel is used: for the manufacture of castings parts, high tensile strength for chemical industry, working in environments of medium aggressiveness (nitrogen and weak organic acids, solutions of salts of organic and inorganic acids); casting investment casting for aircraft industry group I — loaded items with the specific requirements for density and mechanical properties: high load brackets, sealed the housing, the frames of gyroscopes, stabilizers, etc. and group II — non-loaded and lightly loaded parts, rings, flanges, fittings, leaking instrument cabinets, etc.
Note
Steel corrosion resistant martensitic grade, high strength at normal temperature.
