Why Alloy 330 & Incoloy DS Sheets Are the Industry Standard for Extremes
Alloy 330 (UNS N08330, ASTM B536) is a high-performance nickel-iron-chromium alloy explicitly designed for its formidable resistance to oxidizing and reducing media. It features excellent stability in high-temperature environments, especially in sulfuric acid and hydrochloric acid, making it an ideal choice for coolant systems, heat exchangers, and chemical reactor lining.
This alloy’s composition includes approximately 33% nickel, 20% chromium, and 8-10% iron, with minor additions of molybdenum and copper to bolster resistance to general corrosion, stress corrosion cracking, and high-temperature oxidation. Its proven reliability is backed by ASTM B536 standards, with certifications ensuring compliance for critical sectors such as chemical processing, marine, pharmaceutical, and power plants.
Aurico Alloys LLP supplies Alloy 330 & Incoloy DS Sheets in various sizes, surface finishes, and certifications. Our extensive inventory supports swift international delivery, enabling industries to operate continuously without interruption or compromise on safety.

Applications & Benefits
Why this grade
Alloy 330 is a 35% nickel, 19% chromium alloy carrying about 1.2% silicon, and the silicon is the point — it confers the carburisation and thermal-shock resistance that 800 lacks. That makes it the furnace-hardware grade: radiant tubes, retorts, muffles and heat-treatment fixtures cycling to around 1150°C.
- Furnace components in high-temperature oxidizing atmospheres
- Heat exchangers, reformers, and pressure vessels in power plants
- Sour and alkali-resistant piping for chemical industries
- Marine seawater systems, including condenser and cooling pipes
- Pharmaceutical manufacturing equipment with high corrosion resistance
