Details description
Chemical Composition
Carbon (C) content ≤0.03%, Silicon (Si) ≤0.10%, Manganese (Mn) ≤0.10%, Nickel (Ni) content 18.00%-19.00%, also contains cobalt, molybdenum, titanium, aluminum and other elements, as well as trace amounts of boron, zirconium, and calcium used to remove impurities and improve processing performance.
Mechanical Properties
Solution-treated hardness is 28-30HRC, after aging, tensile strength can reach 2000-2900MPa, yield strength is 1600-2000MPa, elongation 10%-15%, impact absorption energy ≥47J (-20℃), can maintain more than 80% strength retention rate below 500℃, and can withstand 600℃ high-temperature impact for a short time.
Performance Characteristics
High Strength and High Toughness: Through the precipitation strengthening of intermetallic compounds, a balance between high strength and high toughness is achieved. Its microstructure is based on high dislocation density lath martensite. After aging, nanometer-scale intermetallic compounds are precipitated, significantly improving strength while maintaining good toughness.
Good Machinability: It can easily handle cutting, EDM, welding, forging, polishing, and coating processes, with excellent machinability.
Small Heat Treatment Deformation: Small deformation after aging heat treatment, which is convenient for manufacturing high-precision parts and can meet the needs of parts processing with strict dimensional tolerance requirements.
Strong Corrosion Resistance: The high nickel content and the combination of other alloying elements give it strong corrosion resistance, effectively preventing oxidation and corrosion in high-humidity environments such as marine and chemical industries.
Product Specifications
Usually, it can be produced into various specifications such as plates, bars, and tubes according to needs. Specific dimensions can be customized according to customer requirements.
Implementation Standards
Including ASTM A564/A564M, GB/T 1222, and ISO 683-17, etc.
Application Fields
Widely used in aerospace, for manufacturing aero-engines, high-speed aircraft components, etc.; in automotive manufacturing, it can be used to manufacture engine components, transmission systems, etc.; it is also suitable for the manufacturing of weapons and equipment and key structural parts in the military industry, as well as in the petroleum, chemical, energy, and marine engineering fields with high material performance requirements.
