Description
Hastelloy C-4 is a nickel-chromium-molybdenum alloy known for its exceptional resistance to stress corrosion cracking, pitting, and crevice corrosion in aggressive environments, including both oxidizing and reducing conditions.
The alloy is particularly distinguished by its high resistance to grain-boundary precipitation, which allows it to maintain its corrosion resistance even after welding and heat treatment, making it a prime choice for chemical process industries.
Its improved thermal stability sets it apart from other Hastelloy alloys, especially in temperatures up to 1040°C (1900°F). Typical applications include chemical reactors, heat exchangers, and other equipment that handle hot, corrosive media. Alloy C-4’s resilience in high-temperature acidic environments makes it particularly effective in chemical manufacturing and pollution control systems.
