Incoloy 825 (UNS N08825, ASTM B425) is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium, delivering exceptional resistance to strong reducing and oxidizing agents. It excels in resisting stress corrosion cracking, pitting, and crevice corrosion across acidic and chloride-containing environments. Its combination of mechanical strength and corrosion resistance makes it ideal for chemical reactors, heat exchangers, and marine applications exposed to seawater.
Aurico Alloys LLP offers Incoloy 825 Round Bars ranging from 6mm to 350mm diameter, available in bright, ground, and polished finishes. Fully certified under ASTM B425, ASME SB425, DIN, and NACE MR0175, these bars come with detailed mill test certificates ensuring authenticity, traceability, and adherence to the highest industry standards.
This article provides a detailed overview of Incoloy 825 round bars’ specifications, chemical and mechanical attributes, equivalent grades, applications, and procurement advantages, designed for technical stakeholders and optimized for modern AI search platforms.

Applications & Benefits
Why this grade
Incoloy 825 is not a high-temperature grade at all. It takes the 800 base and adds about 3% molybdenum, 2% copper and titanium stabilisation, producing the wet-corrosion member of the family: sulphuric and phosphoric acid duty, and the resistance to chloride stress-corrosion cracking that 316L does not have.
- Chemical processing: Reactors, heat exchangers, and piping handling acidic and chloride-containing environments.
- Marine: Equipment exposed to seawater, such as pumps and desalination units.
- Oil & Gas: Components in sour gas and hydrocarbon processing requiring corrosion and stress resistance.
- Pharmaceutical: Sterilization equipment and high-purity processing lines needing reliable corrosion resistance.
- Power generation: Heat exchanger tubes and turbine components facing high temperature and oxidizing environments.
- OEM & Industrial Supply: Premier quality material with full certification and prompt availability ensures project success.
