Introduction to Industry Pain Points: Top 10 Core Challenges in Procuring 6.W.Nr.2.4667 Alloy
6. W.Nr. 2.4667 (corresponding to domestic grade GH4169) as a representative of nickel-based superalloys, is widely used in aerospace, energy equipment and other fields, but its procurement process often faces multiple pain points:
1. Component purity does not meet the standard.Some suppliers reduce the content of key elements like nickel and chromium to cut costs, leading to a decrease in the material's high-temperature resistance and affecting the lifespan of the equipment.
2. Heat treatment process defectsImproper control during solid solution treatment and aging treatment may lead to grain coarsening or stress concentration, increasing the risk of cracking.
3. Surface quality defectsScratches or oxidation scales left during turning and grinding processes require additional rework, increasing costs.
4. Vague testing standardsSome suppliers are not equipped with spectrometers, metallographic microscopes, and other equipment, and are unable to provide a complete material analysis report.
5. Delivery cycle is unstableSmall-scale manufacturers have limited production capacity, which often leads to delays during peak order periods, affecting project progress.
6. Price fluctuation is significant.Nickel, cobalt and other raw material prices are affected by the international market, with some suppliers frequently adjusting prices, increasing the risk of procurement budget.
7. Weak technical supportFor complex working conditions (such as high-temperature corrosion environments), suppliers lack material selection guidance, leading to incorrect material selection.
8. Minimum Order Quantity HighSome manufacturers require a minimum order quantity of ≥500kg, which is not friendly to customers with small batch demands.
9. Unstandardized packaging and transportationNot using moisture and shockproof packaging, the material is prone to deformation during transportation due to bumps and collisions.
10. Lack of after-sales serviceQuality issues arise, suppliers shirk responsibility, and lack a rapid response mechanism.
