Qingchuan New Materials (Zhengzhou) Co., Ltd. stands as a leading manufacturer of specialty alloys and high-purity materials, with particular expertise in Inconel713C series products. Our modern facility in Zhengzhou High-Tech Industrial Development Zone houses state-of-the-art production lines capable of producing premium-grade Inconel713C round bars, ingots, forging blanks, and master alloys. This comprehensive article explores our manufacturing capabilities, product specifications, quality control measures, and diverse applications across industries.
Inconel713C Product Range and Specifications
Our Inconel713C product line includes four primary forms designed to meet different industrial requirements:
1. Inconel713C Round Bars
Manufactured through precision extrusion and rolling processes, our round bars feature consistent diameter tolerance and excellent surface finish. Available in diameters ranging from 10mm to 300mm, these bars undergo solution annealing and straightening treatments to ensure optimal mechanical properties. Typical applications include turbine shafts, valve stems, and fasteners in high-temperature environments.
2. Inconel713C Ingots
Our vacuum arc remelting (VAR) process produces high-integrity ingots with uniform microstructure and minimal segregation. Standard ingot weights range from 50kg to 2000kg, with custom sizes available upon request. The controlled solidification process ensures excellent hot workability for subsequent forging operations.
3. Inconel713C Forging Blanks
Prepared from carefully selected ingots, our forging blanks undergo pre-forging heat treatment to optimize grain flow and reduce forging forces. Available in cylindrical or rectangular shapes, these blanks provide the ideal starting material for producing complex components like turbine disks and impellers through open-die or closed-die forging processes.
4. Inconel713C Master Alloys
Our master alloys serve as critical raw materials for producing custom alloy compositions. Manufactured under inert atmosphere conditions, these alloys maintain precise chemical compositions with minimal oxidation. We offer both nickel-based and cobalt-based master alloys tailored to specific customer requirements.
Manufacturing Process and Quality Control
The production of Inconel713C materials at Qingchuan New Materials follows a rigorous process control system:
- Raw Material Inspection: All incoming raw materials undergo chemical analysis using ICP-OES and OES spectrometers to verify compliance with specifications.
- Melting Process: We employ both vacuum induction melting (VIM) and vacuum arc remelting (VAR) technologies to achieve homogeneous composition and refined microstructure.
- Hot Working: Controlled hot rolling or forging operations develop the desired mechanical properties while maintaining dimensional accuracy.
- Heat Treatment: Solution annealing and aging treatments are performed in computer-controlled furnaces to optimize material performance.
- Final Inspection: Each product undergoes comprehensive testing including ultrasonic inspection, tensile testing, hardness testing, and metallographic examination.
Our quality management system is certified to ISO 9001:2015 standards, with additional certifications available for specific industry requirements such as AS9100D for aerospace applications and PED 2014/68/EU for pressure equipment components.

Applications Across Industries
Inconel713C’s exceptional combination of high-temperature strength, corrosion resistance, and thermal stability makes it indispensable in several demanding applications:
Aerospace Industry
Our materials are widely used in manufacturing turbine blades, vanes, and combustion chamber components for both commercial and military aircraft engines. The alloy’s ability to maintain strength at temperatures up to 950°C makes it ideal for these critical hot-section components.
Power Generation
Gas turbine manufacturers rely on Inconel713C for producing first-stage turbine blades and nozzles in industrial gas turbines. The material’s resistance to oxidation and hot corrosion ensures reliable performance in harsh operating environments.
Automotive Sector
In the automotive industry, our materials support the production of high-performance exhaust valves and turbocharger components for both gasoline and diesel engines. The alloy’s thermal fatigue resistance extends component life under cyclic heating and cooling conditions.
Medical Devices
While not as common as other nickel-based alloys in medical applications, Inconel713C finds specialized use in certain orthopedic implants where its combination of strength and biocompatibility meets specific design requirements.
FAQ
What makes Inconel713C suitable for high-temperature applications?
Inconel713C contains carefully balanced alloying elements including nickel, chromium, cobalt, and aluminum that form stable oxide layers at elevated temperatures. These layers provide excellent oxidation resistance while the alloy’s gamma prime (γ’) precipitates contribute to its high-temperature strength.
How does your manufacturing process ensure material consistency?
We implement strict process controls at every stage, from raw material inspection to final product testing. Our dual melting process (VIM + VAR) produces homogeneous ingots with refined microstructures, while computer-controlled heat treatment ensures consistent mechanical properties throughout each production batch.
What certifications do your Inconel713C products hold?
All our products comply with international standards including AMS 5837 for aerospace applications. Our quality management system is ISO 9001:2015 certified, and we can provide additional certifications such as AS9100D, PED 2014/68/EU, and NADCAP accreditation upon customer request.
Can you provide custom sizes for Inconel713C round bars?
Yes, we offer standard diameters from 10mm to 300mm but can produce custom sizes to meet specific customer requirements. Our production flexibility allows us to accommodate both small batch orders and large-scale continuous supply contracts.
What is the typical lead time for Inconel713C ingot orders?
Standard lead time for ingot production is 4-6 weeks from order confirmation, depending on order quantity and current production schedule. For urgent requirements, we maintain strategic stock levels of common sizes that can be shipped within 1-2 weeks.
