ZYTC Alloy is proud to announce the successful completion and delivery of a significant export order of Alloy X750 (UNS N07750) to Russia. This shipment consisted of Grade 1 round Bars with a diameter of 16mm and a length of 7000mm, manufactured in strict compliance with theASTM B637 standard. The entire production and inspection process was meticulously managed under our standardized, procedural, and specialized framework, with the final product receiving full certification of compliance from an independent third-party inspection agency.
This order underscores our commitment to delivering high-quality, reliable nickel-based superalloys to the global market. In addition to round bars, ZYTC Alloy possesses extensive capabilities in producing a wide range of Alloy X750 forms, including sheets, strips, wires, bars, capillary tubes, seamless tubes, and forgings, all adhering to stringent international standards such as ASTM, EN, and AMS.
An In-Depth Look at Alloy X750 (UNS N07750)
Alloy X750 is a precipitation-hardenable nickel-chromium Alloy Known for its exceptional combination of high strength and excellent corrosion resistance at temperatures up to 1300°F (700°C). Its performance is derived from a careful balance of chemical composition and a controlled heat-treatment process.
Alloy X750 Chemical Composition
The key to Alloy X750's properties lies in its precise chemistry, as specified by ASTM B637. The primary components are:
-
Nickel (Ni): Bal. - Provides the fundamental matrix and base corrosion resistance.
-
Chromium (Cr): 14.0 - 17.0% - Confers resistance to oxidation and high-temperature corrosion.
-
Iron (Fe): 5.0 - 9.0% - A strengthening element.
-
Titanium (Ti): 2.25 - 2.75% - A primary hardening element through the formation of the gamma prime phase [Ni3(Ti,Al)] during aging.
-
Aluminum (Al): 0.40 - 1.00% - Works in concert with Titanium as a hardening element.
-
Columbium (Cb) + Tantalum (Ta): 0.70 - 1.20% - Contributes to strengthening and stabilization.
-
Carbon (C), Manganese (Mn), Silicon (Si), Sulfur (S), Copper (Cu): Present in controlled, minimal amounts to ensure weldability, fabricability, and to prevent the formation of undesirable phases.
Alloy X750 Mechanical Properties
When heat-treated according to the standard requirements for ASTM B637, Alloy X750 Grade 1 exhibits outstanding mechanical properties. Typical room temperature properties include:
-
Tensile Strength: 1350 MPa (min)
-
Yield Strength (0.2% Offset): 830 MPa (min)
-
Elongation: 20% (min)
These properties make it significantly stronger than many stainless steels and other nickel alloys while maintaining good ductility.
Alloy X750 Key Applications
Due to its robust performance profile, Alloy X750 is the material of choice for demanding applications across various industries:
-
Aerospace: Gas turbine engine parts, such as blades, rings, and critical fasteners.
-
Industrial Gas Turbines: Turbine wheels, buckets, and bolts operating under high stress and temperature.
-
Nuclear Power Systems: Used for core components, springs, and fasteners requiring high strength and radiation resistance.
-
Chemical Processing: Equipment exposed to corrosive environments at elevated temperatures.
-
Oil & Gas: Downhole tooling and components for high-pressure, high-temperature (HPHT) wells.
