Hastelloy C276 Chloride Resistant Castings for Offshore Equipment

Hastelloy C276 Castings: Premium nickel-molybdenum-chromium alloy castings featuring outstanding chloride corrosion resistance, tailored for severe marine, seawater and offshore harsh corrosive working environments.

C ≤0.015, Cr:14.5–16.5, Mo:15.0–17.0, Fe:4.0–7.0, Co ≤2.5, Balance Ni, Si ≤0.08, S ≤0.01

• Exceptional resistance to chloride ion erosion, effectively avoid pitting & stress corrosion cracking in seawater splash zone and submerged area
• Outstanding tolerance to oxidizing & reducing mixed acid, brine and offshore sulfur-containing corrosive medium
• Stable mechanical property from low temperature up to 540℃, reliable under alternating marine temperature
• Dense casting structure, low porosity, good pressure bearing capacity for high-pressure offshore piping system
• Excellent weldability, no post-weld sensitization corrosion risk
