CC276 Hastelloy Alloy Plate | Unmatched Corrosion Resistance for Extreme Environments

✓ Acid & Chloride Dominance: Resists boiling 10% sulfuric acid and 15% hydrochloric acid – 2x lifespan vs. 316L.

✓ Pitting Resistance: PREN ≥69, validated by 25,000+ hours in ASTM G48 Method D seawater testing.

✓ Thermal Stability: Retains strength from **-150°C to 400°C (-238°F to 752°F).

✓ Welding Versatility: Low carbon content (0.01% max) minimizes carbide precipitation during welding (ERNiCrMo-4 filler recommended).

C276 Hastelloy Alloy Plate (UNS N10276)

Engineered to excel in the harshest chemical and high-temperature environments, C276 Hastelloy alloy plate delivers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC). With a nickel-molybdenum-chromium composition (Ni-57%, Mo-16%, Cr-15.5%, W-4%), this superalloy outperforms conventional stainless steels and even other nickel alloys in both oxidizing and reducing acids. Certified to ASTM B575, ASME SB-575, and NACE MR0175, it is the go-to choice for chemical processing, pollution control, and oil & gas applications where reliability is non-negotiable.
