AMS 5844 – ALLOY BARS, HIGH STRENGTH, CORROSION RESISTANT – 35Ni – 35Co – 20Cr – 10Mo – Solution Heat Treated, Cold Drawn, Centerless Ground. AMS 5844 specification covers a high-strength, corrosion-resistant alloy in the form of bars. MP35N® is an age-hardenable quaternary superalloy containing nickel, cobalt, chromium, and molybdenum. The alloy combines ultra-high strength, toughness, and outstanding corrosion resistance. It may be used in the annealed condition but can easily be worked to tensile strength levels above 260 ksi (1,793 MPa) . The heat treatment process can raise the tensile strength by an additional 40 ksi (276 MPa) . ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering AMS 5844 MP35N alloy bar at factory-direct prices with full material traceability and fast global delivery.

Operating Conditions & Selection CriteriaMP35N cold drawn bar is specified when designers require a superalloy that combines ultra-high strength (260-270 ksi) with outstanding corrosion resistance and toughness across a wide temperature spectrum. Ultra-High Strength: Through cold work and aging, MP35N achieves tensile strength from 260 ksi (work-strengthened) up to 270 ksi (aged) — an additional 40 ksi gain through heat treatment Corrosion Resistance: Outstanding resistance to general corrosion, stress corrosion cracking, and crevice corrosion in chloride solutions, salt water, hydrogen sulfide (H₂S), and mineral acids (hydrochloric, nitric, and sulfuric) Wide Service Temperature: Performs reliably from cryogenic temperatures (no embrittlement) up to 600°F (315°C) Biocompatibility: Suitable for medical implants, orthodontic devices, and prosthetic components (ASTM F562 / ISO 5832-6) Sour Gas Service: NACE MR0175/ISO 15156 approved for H₂S environments in oil and gas applications Fatigue Strength: Excellent fatigue properties for cyclic loaded components
ApplicationsOil & Gas: Downhole tools, wellhead equipment, valve stems, packers, completion hardware H₂S sour gas service (NACE MR0175 approved) Seawater and brine handling components
Aerospace: High-strength fasteners (bolts, studs, nuts). Jet engine components, landing gear hardware, actuator rods
Medical: Surgical implants, orthopedic fixation devices, spinal hardware (ASTM F562 / ISO 5832-6) Orthodontic wires, prosthetic components, pacemaker leads
