Hastelloy C2000 Round Bar (UNS N06200)
Hastelloy C2000 Round Bar is a nickel–chromium–molybdenum alloy with added copper, designed to deliver exceptional resistance to both oxidizing and reducing corrosive environments. It is one of the most versatile alloys in the Hastelloy C family, offering outstanding performance in sulfuric acid, hydrochloric acid, nitric acid, and mixed acid conditions.
The unique copper addition significantly improves resistance to sulfuric acid while maintaining excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Hastelloy C2000 Round Bar (also known as Alloy C2000 Round Bar) provides good mechanical strength, excellent fabricability, and weldability, making it ideal for demanding chemical processing applications.
