Hastelloy C-4/NS335/NS3305/N06455/2.4610/NiMo16Cr16Ti Bolt Standard for Performance and Reliability in Extreme Environments
Hastelloy C-4 (UNS N06455, W.Nr. 2.4610, NS335, NS3305) is a nickel-molybdenum-chromium alloy known for its exceptional corrosion resistance, particularly in strong oxidizing and reducing environments. This alloy is highly resistant to stress corrosion cracking, pitting, and crevice corrosion, making it ideal for harsh chemical processing industries.
Bolts made from Hastelloy C-4 are widely used in industries such as chemical processing, aerospace, and marine applications due to their superior mechanical strength and high-temperature stability. They maintain excellent corrosion resistance in acidic environments, including hydrochloric, sulfuric, and phosphoric acids. The presence of titanium enhances thermal stability, preventing grain boundary precipitation and ensuring long-term durability in extreme conditions.
