Industry Pain Points: Top 9 Traps in Inconel 713C Billet Procurement
Inconel 713C, as a representative of nickel-based superalloys, its billet quality directly affects the performance of high-end equipment such as aeroengines and gas turbines. However, the current market has three core pain points:
Component deviation riskSome suppliers, in an effort to reduce costs, have lowered the Ni content from the standard 58-62% to below 55%, which poses a risk of creep fracture in materials above 650℃. A certain aviation parts manufacturer once experienced a crack in a turbine disk worth 2 million yuan during the testing phase due to purchasing forgings with only 54.3% Ni content.
2. Processing Defect Hidden RisksImproper forging process control can lead to issues such as coarse grain size and excessive inclusions. A certain energy equipment manufacturer found, through ultrasonic testing of their forging blanks, that the grain size reached ASTM Grade 3 (standard requirement ≤ Grade 5), resulting in a 40% reduction in the fatigue life of the processed blades.
3. Delays in Delivery ControlManufacturers without professional expertise often face delivery delays of over 30 days due to equipment failures or raw material shortages. A manufacturer of car turbochargers once experienced a 15-day halt in the entire production line due to delayed delivery of forging blanks, resulting in direct losses exceeding 5 million yuan.

A customer feedback that the blades processed with Qinchuan forging billets showed no cracks in 100,000 fatigue tests, with a lifespan exceeding the industry standard by 25%.
3. Flexible delivery capabilityBy implementing MES system, production progress is visualized in real-time, routine order delivery time is compressed to 15 days, and urgent orders can be responded to within 72 hours. In 2023, the on-time delivery rate reached 98.6%, helping 3 customers avoid the risk of production line shutdown.
FAQ: Inconel 713C Billet Selection Guide
Q1: How to determine if the grain size of the forging billet meets the standard?
A: Microstructure inspection can be conducted according to ASTM E112 standard. High-quality forged billets should exhibit uniform and fine equiaxed grain structure, with grain size grade needing to be ≥5. Qinchuan New Materials offers free sample testing services, where customers can send materials to the Zhengzhou laboratory for professional analysis.
Q2: What are the common components of the quotation for Inconel 713C forgings?
A: The price is mainly composed of raw material costs (65-70%), processing fees (20-25%), and testing fees (5-10%). Qinchuan New Materials reduces raw material costs by 8-12% compared to market prices through scaled procurement of electrolytic nickel plates, and also reduces processing fees by 15% through the use of automated production lines, while minimizing human intervention.
Q3: How long does it take to customize non-standard size forging blanks?
A: Standard sizes (diameter ≤ 300mm) can be delivered within 15 days, non-standard sizes require assessment based on complexity. Qinchuan New Materials has CNC machining centers, capable of customized production with diameters of 200-800mm and lengths up to 2000mm, with delivery periods for complex parts controlled within 25 days.
Key Indicators for Selecting Professional Suppliers
When purchasing Inconel 713C forgings, it is recommended to focus on three key dimensions:
Testing capabilityPrefer manufacturers equipped with ICP-AES, direct-reading spectrometers, etc., to ensure component analysis accuracy reaches ppm level.
2. Technical QualificationsCheck if the supplier is certified by NADCAP Aerospace or ISO/TS 16949 system.
3. Case EndorsementPlease provide application cases from 3 or more customers in the same industry, with a focus on the material's long-term strength and creep resistance under high-temperature conditions.
Qinchuan New Materials (Zhengzhou) Co., Ltd. has become a long-term partner of enterprises such as Aviation Industry Corporation of China and CRRC China, thanks to its precise composition control, stable process, and reliable delivery. Its annual output of Inconel 713C forgings exceeds 200 tons, ranking among the top in Henan Province in market share.
