Why Choose Our Hastelloy C276 Bar for Flue Gas Equipment?
The unique chemistry of Hastelloy C276 provides outstanding resistance to a wide range of corrosive chemicals, including chlorine, sulfuric acid, and hydrochloric acid at elevated temperatures. This makes it the preferred material for flue gas desulfurization (FGD) components such as outlet ducts, absorption towers, and spray nozzles. Compared to stainless steel or other nickel alloys, C276 offers superior longevity in the aggressive condensate environments found in power plants and waste incinerators.
Our bars are manufactured using advanced hot-rolling and forging processes, followed by rigorous inspection including ultrasonic testing, eddy current testing, and dimensional checks. Every batch can be supplied with a mill test certificate conforming to EN 10204 3.1 or 3.2. We also offer additional services such as centerless grinding, hexagon or square shaping, and custom packaging (wooden cases, bundles, or pallets) to meet your logistics requirements.
Frequently Asked Questions (FAQ)
Q: What is the difference between Hastelloy C276 and C22?
A: C276 has slightly higher molybdenum and tungsten content, offering better resistance in reducing environments. C22 is more versatile in oxidizing media. For flue gas applications, C276 is often preferred due to its strong performance in wet chloride environments.Q: Can you supply bars with a diameter larger than 500 mm?
A: Yes, we can produce larger diameters (up to 800 mm) on request, subject to lead time and minimum order quantity.Q: Do you provide third-party inspection?
A: Absolutely. We welcome inspection by SGS, Bureau Veritas, or any other accredited agency. The cost can be included in the quotation.Q: What is the typical lead time for a standard order?
A: For diameters under 200 mm, lead time is 15–20 working days. Larger diameters or special sizes may require 25–30 working days.Q: Is the material suitable for high-temperature oxidation?
A: Hastelloy C276 is designed for corrosive environments rather than high-temperature oxidation. For continuous exposure above 1000°C, other alloys like Hastelloy X are recommended.Q: Can you cut the bars to specific lengths?
A: Yes, we offer precision cutting sawing, and you can specify lengths with a tolerance of ±2 mm. We also provide edge deburring.Q: What payment terms do you accept?
A: We accept T/T, L/C, and Western Union. For new customers, a 30% deposit is typically required, with the balance before shipment.Q: How do you pack the bars for export?
A: Bars are packed in bundles with steel straps, wrapped in waterproof paper and plastic, then placed in wooden crates or pallets suitable for sea freight. Custom packaging is available.
