Frequently Asked Questions
What is the difference between Incoloy 825 and Inconel 625?
While both are nickel-based, Incoloy 825 has a higher iron content and is optimized for acid resistance and cost. Inconel 625 has more nickel and niobium, making it stronger at much higher temperatures (above 600℃), but significantly more expensive.
Is UNS N08825 suitable for seawater?
Yes. Due to its molybdenum and chromium content, it resists the pitting and crevice corrosion typically caused by high-chloride seawater environments.
What is the typical lead time and price?
Prices currently fluctuate between $29.70 and $39.60 per kg depending on the market. Seamless tubes are typically supplied in the annealed condition to ensure maximum corrosion resistance.
