Hastelloy C-4/NS335/NS3305/N06455/2.4610/NiMo16Cr16Ti Alloy Bar For Harsh Chemical Processing

Hastelloy C-4 (NS335, NS3305, N06455, 2.4610, NiMo16Cr16Ti) is a nickel-molybdenum-chromium alloy known for its exceptional resistance to high-temperature oxidation and aggressive chemical environments. This alloy offers superior stability at elevated temperatures (up to 1038°C) and excellent corrosion resistance in strong oxidizing and reducing conditions, making it ideal for chemical processing, power plants, and aerospace applications.

With a high molybdenum and chromium content, Hastelloy C-4 resists pitting, stress corrosion cracking, and crevice corrosion. It also has enhanced weldability and thermal stability due to its controlled carbon and silicon content. Common forms include bars, sheets, plates, and pipes, used in reactors, heat exchangers, and acid production equipment.

This alloy is particularly valued for its mechanical strength and oxidation resistance in extreme conditions, ensuring long-term durability in harsh environments. Hastelloy C-4 bars are widely used in industries requiring high performance and corrosion resistance.
