Alloy C4 / UNS N06455 / 2.4610
Alloy C4 / UNS N06455 / 2.4610– high corrosion resistance
Properties of Alloy C4 / UNS N06455 / 2.4610
Alloy C4 / UNS N06455 / 2.4610 is a low-carbon, austenitic nickel-molybdenum-chromium alloy engineered for exceptional corrosion resistance. It demonstrates:
Key Features:
- Outstanding resistance to pitting, crevice, and stress corrosion cracking
- High stability against intergranular corrosion, even after welding
- Excellent performance in reducing environments, including hot contaminated acids
- Good weldability, typically used in the as-welded condition without post-weld heat treatment strength even under extreme conditions
Applications of Alloy C4 / UNS N06455 / 2.4610
Alloy C4 / UNS N06455 / 2. 4610 is widely used in industries requiring high corrosion resistance under aggressive chemical conditions.
- Chemical processing: heat exchangers, reactors, piping systems
- Environmental engineering: flue gas desulfurization, waste incineration
- Fertilizer and pesticide production
- Acid storage and transport vessels
- Pharmaceutical and petrochemical equipment
- Oil & gas (manifolds, valves, drilling tools and components)
