Q: What is Hastelloy W UNS N10004 mainly used for?
A: Hastelloy W is specially designed for high-temperature structural components and dissimilar alloy welding. It is widely used in gas turbine parts, aerospace components, high-temperature furnace fixtures and molten salt corrosion equipment.
Q: What is the maximum working temperature of Hastelloy W bar?
A: It can maintain stable mechanical performance and creep resistance at continuous working temperature up to 870°C, suitable for long-term high-temperature thermal cycling environments.
Q: What are the advantages of Hastelloy W compared with other Hastelloy alloys?
A: Hastelloy W has outstanding dissimilar metal welding performance and excellent high-temperature creep resistance. It avoids high-temperature embrittlement and is more suitable for thermal cycle and turbine component applications than conventional corrosion-resistant Hastelloy grades.
Q: Can you provide custom sizes and precision processing?
A: Yes. We support custom diameter, fixed length cutting, surface polishing, forging and heat treatment services to meet different precision mechanical and high-temperature equipment requirements.
Q: What quality reports can you provide?
A: We provide ISO certification, MTC 3.1/3.2 factory test certificate, PMI spectral composition test, tensile, hardness and creep property test reports. Third-party inspection is acceptable.
Q: What is your MOQ and delivery time?
A: MOQ is 5KG for small trial orders. Standard stock orders can be delivered within 12–20 working days.
