The Nickel-Based Superalloy Round Bar GH3030 (also designated as NUS N06600) is a classic and widely trusted heat-resistant alloy and corrosion-resistant alloy engineered for extreme operating conditions. As a flagship product in nickel-based superalloy categories, it combines exceptional chemical stability, mechanical strength, and environmental adaptability, making it a preferred choice across industries that demand reliability in high-temperature and corrosive environments. GH3030 round bar is formulated with a precise blend of nickel, chromium, and other trace elements, adhering to strict industrial standards to ensure consistent performance in critical applications. Whether used in structural components or functional parts, this high-temperature superalloy delivers long-term durability and resistance to degradation, outperforming conventional alloys in harsh settings.
GH3030’s chemical makeup is carefully balanced to enhance its core properties. With a nickel (Ni) content ranging from 68% to 76% (min to max), it provides a stable austenitic matrix that forms the foundation of its corrosion resistance and high-temperature stability. Chromium (Cr) levels between 19% and 22% further boost oxidation resistance and resistance to acidic and alkaline corrosives, while strict controls on impurities—such as carbon (C ≤ 0.12%), sulfur (S ≤ 0.015%), and phosphorus (P ≤ 0.02%)—ensure minimal brittleness and maximum structural integrity. Trace additions of titanium (Ti) and aluminum (Al) (each 0.15-0.35%) refine the alloy’s microstructure, enhancing its mechanical strength without compromising ductility.
Density: With a density of 8.4g/cm³, GH3030 round bar offers a favorable strength-to-weight ratio, making it suitable for both lightweight and heavy-duty applications.
Melting Point: Its melting range of 1374-1420℃ allows it to retain structural stability even in near-molten environments, distinguishing it from standard alloys that soften or deform at high temperatures.
Thermal Stability: The alloy maintains consistent physical properties across a wide temperature spectrum, from room temperature to extreme heat, ensuring predictable performance in fluctuating conditions.
At room temperature, GH3030 round bar exhibits impressive mechanical properties after solution treatment:
Tensile Strength (Rm): 785 N/mm², enabling it to withstand high tensile loads without fracture.
Yield Strength (Rp0.2): 270 N/mm², ensuring resistance to permanent deformation under stress.
Elongation Rate (a5): 35%, providing excellent ductility for forming, bending, and machining processes.
These properties make the alloy highly workable, allowing for fabrication into complex shapes while retaining its structural integrity and performance capabilities.
