C276 Hastelloy clad steel plate is a composite metal plate made by bonding a corrosion-resistant Hastelloy C276 / UNS N10276 alloy layer onto a structural steel base plate. The C276 layer provides resistance to strong acids, chlorides, oxidizing media, reducing environments, pitting, crevice corrosion and stress corrosion cracking, while the steel backing offers mechanical strength, weldability and cost control.
Compared with solid Hastelloy C276 plate, C276 clad steel significantly reduces nickel alloy consumption while maintaining corrosion protection on the working surface. This makes it suitable for large pressure vessels, reaction tanks, tube sheets, heat exchangers, scrubbers, evaporators and chemical storage equipment.
Hastelloy C276 is widely recognized for resistance to chloride-bearing solutions, oxidizing and non-oxidizing acids, and localized corrosion environments. Its low carbon content also helps reduce carbide precipitation in welded heat-affected zones.

Corrosion Resistance Analysis
C276 Hastelloy clad steel plate is suitable for highly corrosive environments such as:
Wet chlorine and chlorine dioxide systems
Sulfuric acid and phosphoric acid equipment
Hydrochloric acid-related process environments
Ferric chloride and cupric chloride solutions
Seawater and brine systems
Flue gas desulfurization slurry
Chemical reaction vessels
Acid recovery and evaporation systems
The alloy is especially valued for resistance to localized corrosion such as pitting, crevice corrosion and chloride-induced stress corrosion cracking.
Fabrication Performance
C276 clad steel plate can be processed into industrial components through:
Plate cutting
Rolling
Forming
Bending
Welding
Drilling
Tube sheet machining
Head forming
Nozzle opening
Surface polishing
During fabrication, the C276 layer should be protected from carbon steel contamination. Dedicated tools, controlled welding procedures and proper pickling/passivation are recommended for corrosion-critical equipment.
Welding Performance
C276 has good weldability and can be welded using suitable nickel alloy filler metals. Its low carbon content helps maintain corrosion resistance in welded heat-affected zones.
Recommended welding considerations:
Use qualified WPS/PQR for clad steel structure
Avoid iron contamination on C276 surface
Select nickel alloy welding consumables for cladding layer
Use carbon steel consumables for base layer when applicable
Control dilution between base metal and clad metal
Perform PT/UT/RT testing when required
Apply pickling and surface cleaning after welding
Composite Plate Performance
The final mechanical performance depends on:
Base steel grade
Cladding thickness
Bonding method
Heat treatment condition
Plate thickness
Customer design standard
For pressure vessel use, mechanical testing, bending test, shear strength test and ultrasonic inspection can be arranged according to purchase specifications.
