Industry Pain Points: Challenges and Demands in Nickel-based High-Temperature Alloy Manufacturing

Nickel-based superalloys, as core materials for high-end equipment such as aircraft engines and gas turbines, face multiple challenges in their manufacturing process. Firstly, precise control of the alloy composition is required, with any deviation in the proportions of elements like nickel, chromium, and cobalt exceeding 0.1% potentially leading to a decrease in material properties. Secondly, the high-temperature melting process must be completed above 1600°C, demanding stringent requirements for equipment thermal resistance and vacuum. Furthermore, the subsequent heat treatment stage needs to achieve grain refinement through multi-level solution and aging treatments, with any slight deviation in process parameters affecting the material's high-temperature strength and creep resistance. Additionally, some domestic manufacturers struggle with product batch stability due to insufficient equipment precision or limited detection methods, making it difficult to meet the stringent requirements for material consistency in the aerospace field.

FAQ One-Question-One-Answer Selection Guide

Q1: How to assess the process level of a nickel-based superalloy manufacturer?
A: It can be evaluated from three dimensions: first, equipment accuracy, such as whether the vacuum degree of the vacuum melting furnace reaches 10⁻³Pa level; second, process control, such as whether the heating rate of heat treatment can be precisely controlled within ±1℃/min; third, detection capability, whether it has a full-process detection method from component analysis to high-temperature endurance performance testing. Qinchuan New Materials adopts the VIM+ESR double melting process, combined with multi-level solid solution treatment, which can achieve fine control of grain size from 5 to 8 levels.

Q2: What is the composition of the quotation for nickel-based alloys?
A: The quotation mainly includes raw material costs (60%-70%), smelting and processing fees (20%-30%), and testing fees (5%-10%). Taking Inconel 718 alloy as an example, the price fluctuations of raw materials such as nickel and cobalt directly affect the cost, and the complexity of the smelting process (such as the use of electroslag remelting) and testing items (such as whether high-temperature creep testing is included) will also significantly affect the final quotation. Qinchuan New Materials can control the cost around 90% of the industry average through scaled procurement and process optimization.

Q3: How to verify the batch stability of nickel-based alloys?
A: Key performance indicators such as high-temperature tensile strength (≥900MPa), yield strength (≥620MPa), and elongation at break (≥12%) can be tested through sampling. The fluctuation range of test results for three consecutive batches of products should be less than 5%. Qichuan New Materials uses a MES production execution system to monitor parameters such as melting temperature and heat treatment time in real-time, ensuring the fluctuation rate of product performance is ≤3%.
