Hastelloy C276 Plate Industrial Applications

Hastelloy C276 plates serve 4 key industries where severe corrosion demands a high-performance nickel alloy plate.

Chemical and Petrochemical Processing

Examples of applications for C276 plates include column internals, heat exchangers, and reactor vessels that are subjected to mixed acid streams. Additional applications include column internals.

Flue Gas Desulfurisation (FGD) Systems

FGD scrubber linings and ductwork use C276 plates to resist sulfuric acid, hydrochloric acid, and fluorides.

Oil and Gas Production

Sour gas service components use C276 plates to resist hydrogen sulfide (H2S) corrosion per NACE MR0175.

Pharmaceutical and Food Processing

Reactor vessels and mixing tanks use C276 plate for resistance to aggressive cleaning agents without contaminating high-purity products.

Hastelloy C276 Plates vs. Alternative Alloys

Compare the corrosion resistance and mechanical performance of Hastelloy C276 plates against other high-performance industrial alloys.

Property Hastelloy C276 Hastelloy C22 Inconel 625
Mo Content 15.0-17.0% 12.5-14.5% 8.0-10.0%
Cr Content 14.5-16.5% 20.0-22.5% 20.0-23.0%
Reducing Acid Resistance Superior Good Moderate
Oxidising Acid Resistance Good Superior Good
Chloride SCC Resistance Excellent Excellent Good

Corrosion Resistance of of Hastelloy C276 Plates

Alloy C-276 plate resists corrosion in both oxidising and reducing environments, due to its high molybdenum (15.0-17.0%) and chromium (14.5-16.5%) content.

Resistance to Acids

Hastelloy C276 plates withstand hydrochloric acid up to 20% at room temperature, sulfuric acid across a broad range, and phosphoric acid.

Resistance to Pitting and Crevice Corrosion

C276’s 3.0 to 4.5% tungsten content actively resists localised attacks from chloride contamination, seawater, and wet chlorine gas. This specialised alloy ensures your infrastructure survives in the most aggressive and volatile chemical situations.

Resistance to Stress Corrosion Cracking

Nickel alloy C-276 plate resists chloride-induced stress corrosion cracking in sour gas and chloride-bearing process streams.
