The aerospace and medical industries demand materials that combine exceptional strength, corrosion resistance, and thermal stability. Qingchuan New Materials (Zhengzhou) Co., Ltd. specializes in developing and manufacturing premium specialty alloys that meet these stringent requirements. Our flagship product line featuring Inconel713C (W.Nr.2.4636) has established itself as a critical component in high-performance applications across multiple industries.
Understanding Inconel713C Material Properties
Inconel713C belongs to the nickel-based superalloy family, specifically engineered for applications requiring superior mechanical properties at elevated temperatures. This alloy contains carefully balanced proportions of nickel, chromium, and cobalt, with additional elements like aluminum and titanium to enhance its microstructure through precipitation hardening. The result is a material that maintains its strength up to 1000°C while exhibiting excellent oxidation and hot corrosion resistance.
Our manufacturing process begins with stringent raw material selection. We source only the highest-grade nickel and chromium to ensure consistent quality in every batch. The alloy composition follows ASTM B637 and AMS 5662 standards, with precise control over trace elements to prevent unwanted phases that could compromise performance. This attention to detail makes our Inconel713C particularly suitable for demanding applications in gas turbines, rocket engines, and industrial furnaces.
Comprehensive Product Range for Diverse Applications
Qingchuan New Materials offers a complete range of Inconel713C products tailored to different manufacturing processes:
- Round Bars: Precision-ground to exacting tolerances, our round bars serve as raw material for machining complex components like turbine blades and seals. Available in diameters from 10mm to 300mm, we provide both solution-annealed and age-hardened conditions to match your processing requirements.
- Cast Ingots: For investment casting applications, our vacuum-melted ingots ensure minimal porosity and excellent fluidity during melting. Standard weights range from 5kg to 500kg, with custom sizes available upon request.
- Forging Blanks: Our pre-forged blanks reduce material waste and machining time for forging operations. These blanks undergo preliminary hot working to achieve optimal grain flow before final forging into complex shapes.
- Master Alloys: Designed for alloy modification during melting, our master alloys provide precise control over composition when blending with base metals or other alloys.

Aerospace Industry Applications
The aerospace sector represents one of our most demanding yet rewarding markets for Inconel713C. Jet engine manufacturers rely on this alloy for critical hot-section components that must withstand extreme temperatures and mechanical stresses. Our materials have been successfully integrated into:
- Turbine blades and vanes operating at temperatures exceeding 900°C
- Combustor cans and liners exposed to corrosive combustion gases
- Afterburner components requiring excellent thermal fatigue resistance
- Seal rings and shrouds maintaining dimensional stability under thermal cycling
One notable project involved supplying Inconel713C round bars for a leading European aerospace manufacturer’s new-generation engine program. Our materials underwent rigorous testing including low-cycle fatigue, thermal shock, and oxidation resistance evaluations. The consistent microstructure and cleanliness of our product enabled the customer to achieve a 15% increase in component service life compared to previous materials.
Medical Device Manufacturing Solutions
Beyond traditional industrial applications, our high-purity materials play a vital role in medical technology. The biocompatibility and corrosion resistance of Inconel713C make it an excellent choice for surgical implants and instruments that must endure repeated sterilization cycles. Key medical applications include:
- Artificial joint components requiring long-term stability in the human body
- Dental implant abutments and screws with excellent osseointegration properties
- Surgical instruments needing resistance to various sterilization methods
- Orthopedic fixation devices maintaining mechanical integrity during healing
For a North American medical device OEM, we developed a special processing route for Inconel713C that reduced surface roughness to Ra < 0.2μm while maintaining core mechanical properties. This enabled the customer to eliminate a secondary polishing step in their manufacturing process, reducing production costs by 22% while improving product consistency.
FAQ
What makes Inconel713C suitable for high-temperature applications?
Inconel713C derives its high-temperature capabilities from its nickel-chromium matrix reinforced with gamma prime (Ni3(Al,Ti)) precipitates. These precipitates form during aging treatment and provide exceptional creep resistance up to 1000°C. The alloy’s chromium content ensures excellent oxidation resistance by forming a stable, adherent Cr2O3 surface layer.
How does your production process ensure material consistency?
We implement multiple quality control measures throughout manufacturing: 1) Vacuum induction melting (VIM) followed by electroslag remelting (ESR) for ultra-clean ingots, 2) Precision hot working with controlled deformation ratios, 3) Solution annealing in protective atmospheres, and 4) Multi-stage aging treatments with strict temperature uniformity control. Each batch undergoes comprehensive testing including chemical analysis, mechanical property verification, and microstructure examination.
Can you provide materials with special surface finishes?
Yes, we offer several surface treatment options including: 1) Peel turning for round bars to achieve Ra < 0.8μm, 2) Electropolishing for medical-grade finishes down to Ra < 0.2μm, 3) Black oxide coating for temporary corrosion protection during storage, and 4) Custom grinding services to meet specific dimensional tolerances.
What documentation do you provide with each shipment?
Every delivery includes a complete quality certificate package containing: 1) Mill test report with actual chemical composition, 2) Mechanical property test results, 3) Ultrasonic inspection report (when applicable), 4) Heat treatment charts, and 5) Material traceability records back to raw material batches. For aerospace applications, we can provide EN 9100 compliant documentation.
