Product Description
INCOLOY 825 (UNS N08825) is a nickel-iron-chromium alloy with molybdenum, copper, and titanium additions, designed for exceptional resistance to corrosion in both oxidizing and reducing environments.
It offers outstanding performance in sulfuric acid, phosphoric acid, seawater, and chloride environments, while maintaining excellent mechanical properties from cryogenic to moderately high temperatures (up to about 540°C / 1000°F).
Because of its excellent resistance to pitting, crevice corrosion, and stress-corrosion cracking, INCOLOY 825 is widely used in chemical processing, marine environments, pollution control, and oil & gas industries.
Key Features:
-
Excellent resistance to both oxidizing and reducing acids
-
Outstanding corrosion resistance in sulfuric and phosphoric acids
-
High resistance to chloride-induced stress-corrosion cracking
-
Good mechanical properties up to 540°C (1000°F)
-
Excellent weldability and formability
Typical Applications:
-
Heat exchangers and evaporators
-
Acid production and pickling equipment
-
Marine and offshore pipelines
-
Pollution control and flue gas scrubbers
-
Chemical processing and pressure vessels

Q1: What makes INCOLOY 825 different from INCOLOY 800 series?
A1: INCOLOY 825 contains molybdenum and copper, giving it superior corrosion resistance in acids and seawater, whereas the 800 series is optimized for high-temperature oxidation resistance.
Q2: What environments can INCOLOY 825 withstand?
A2: It performs excellently in sulfuric acid, phosphoric acid, seawater, alkaline salts, and chloride-rich environments.
Q3: Can INCOLOY 825 be welded?
A3: Yes. It can be TIG, MIG, or resistance welded, with welds retaining corrosion resistance equivalent to the base metal.
Q4: What product forms are available?
A4: Sheets, plates, bars, rings, tubes, pipes, fittings, and flanges.
Q5: What certifications can be supplied?
A5: Products are provided with EN 10204 3.1 / 3.2 certificates, including chemical composition and mechanical test reports.
Q6: Are inspection certificates provided?
A6: Yes, EN 10204 3.1 / 3.2 certificates are available, including full chemical analysis and mechanical test reports.
Q7: What is the delivery time?
A7: Usually 7-15 working days for stock materials, and 20-30 days for custom-machined or special-size rings.
Q8: Do you offer price discounts for large quantities?
A8: Yes. We provide big price discounts for bulk orders or long-term cooperation projects. Please contact us for a detailed quotation.
