Performance features
Mechanical properties: Taking flat material products as an example, after precipitation hardening at 510°C, the thickness is unlimited, the tensile strength rm> and yield point re>.
Corrosion resistance: Excellent resistance in corrosive media such as acid and alkali and chloride, and has the ability to resist intergranular corrosion and stress corrosion cracks.
Physical characteristics: It has a low coefficient of thermal expansion, excellent thermal conductivity, and can better adapt to high-temperature working environments.
Application area
Aerospace Field: used to manufacture aircraft landing parts, landing gears, engine parts, structural parts, etc.
Chemical field: It can be used to manufacture steam generators, chemical reactors, purification equipment, pipelines and valves for chemical equipment, etc.
Pharmaceutical industry: usually used in medical devices, artificial joints, implants, etc.
Oil and gas industry: suitable for oil and gas extraction, processing and storage equipment.
Food processing industry: used in the manufacturing of food processing equipment and containers.
Processing and heat treatment
Processing performance: Its plastic can be deformed by cold treatment and heat treatment and can be processed into plates, rods, tubes, belts, wires, cnc services, questions and other products, and has good forging, pullability, pullability and welding.
Heat treatment: Usually includes fixation solution treatment and aging treatment. Fixed solution treatment can obtain uniform tissue in preparation for subsequent aging enhancement. The treatment of aging is to precipitate the enhanced phase in the alloy by insulating heating at a specific temperature, thereby increasing strength and other characteristics.
