Hastelloy C-4/NS335/NS3305/N06455/2.4610/NiMo16Cr16Ti Nut For Aggressive Chemical Environments

Hastelloy C-4 (also known as NS335, NS3305, N06455, 2.4610, NiMo16Cr16Ti) is a nickel-based alloy known for its exceptional resistance to corrosion, particularly in harsh chemical environments. Nuts made from Hastelloy C-4 offer excellent performance in extreme conditions, including exposure to strong oxidizing and reducing agents. This alloy is particularly effective in resisting pitting, stress corrosion cracking, and crevice corrosion, making it ideal for use in chemical processing, power plants, and marine applications.

With a composition rich in nickel, molybdenum, and chromium, Hastelloy C-4 nuts maintain strength and stability even at high temperatures. The addition of titanium enhances thermal stability, preventing embrittlement over extended exposure. These fasteners are commonly used in industries requiring superior corrosion resistance, such as aerospace, pharmaceuticals, and pollution control. Their durability and reliability make them a preferred choice for securing critical equipment in aggressive environments.
