C2000 Hastelloy® Alloy Round Bar (UNS N06200)

Engineered to excel in the most aggressive oxidizing and reducing environments, C2000 Hastelloy® alloy round bar combines a nickel-chromium-molybdenum-copper matrix (Ni-59%, Cr-23%, Mo-16%, Cu-1.6%) to deliver superior resistance to sulfuric acid, hydrochloric acid, and mixed acid-chloride media. Certified to ASTM B574, ASME SB-574, and NACE MR0175, this alloy outperforms traditional C276 and C22 Hastelloy in high-temperature sulfuric acid applications, offering 3x the lifespan of 316L in chemical processing, pharmaceutical, and pollution control industries.

FAQ

Q1: How does C2000 compare to C276 and C22 Hastelloy?

A: C2000 offers superior resistance to mixed acids (e.g., H₂SO₄ + HCl) and higher temperature limits (550°C), while C276 excels in pure HCl and C22 dominates oxidizing acids like HNO₃.

Q2: What welding parameters prevent intergranular corrosion?

A: Use ERNiCrMo-17 filler with TIG welding, limit heat input to **≤1.5 kJ/mm**, and maintain interpass T ≤120°C. Post-weld annealing is not required.

Q3: Are bars certified for nuclear industry use?
