Hastelloy C276 square plate
Hastelloy C276 square plate is a nickel-based high-temperature alloy square plate. It is known for its excellent corrosion resistance and high-temperature stability. The plate is made by hot rolling or cold rolling. The surface is finely processed. It comes in many sizes. Common thicknesses are from 1 mm to 50 mm. The side length can reach 2000 mm. It can be cut to order. The plate is made of nickel (Ni). It also has molybdenum (Mo), chromium (Cr), tungsten (W), and other elements. They form a typical Hastelloy C series alloy structure.
Hastelloy C276 square plate is used in many fields. In the chemical industry, it is used in reactors and acid treatment equipment. In environmental protection, it is used in flue gas desulfurization systems. In marine engineering, it is used in seawater pumps and valves. In the energy sector, it is used in nuclear power and oil and gas extraction. It can withstand strong acids, chlorides, and high-temperature corrosion. Its excellent corrosion resistance and stability greatly extend the life of equipment in harsh environments. It also reduces maintenance costs. It is the top choice for highly corrosive working conditions.
Features of Hastelloy C276 square plate
Excellent Corrosion Resistance:
Hastelloy C276 square plate performs well in both oxidizing and reducing media. It resists strong acids like hydrochloric acid, sulfuric acid, and phosphoric acid. It also resists chloride stress corrosion cracking (SCC). It has excellent resistance to pitting and crevice corrosion, especially in chloride-containing environments like seawater and chemical wastewater.
High-Temperature Performance:
Hastelloy C276 square plate has a wide working temperature range (-196℃ to 1093℃). It keeps its mechanical strength and oxidation resistance at high temperatures.
Processing and Welding:
Hastelloy C276 square plate needs special processes (like low-speed cutting and inert gas shielded welding) to avoid sensitization in the heat-affected zone. But it doesn't need heat treatment after welding.
Stability:
The low iron (Fe) content in Hastelloy C276 square plate reduces carbide precipitation. It is less likely to suffer intergranular corrosion during long-term use.
Applications of Hastelloy C276 square plate
Chemical Industry:
Hastelloy C276 square plate is used to make reactors, heat exchangers, and piping systems. It is used in strong acid environments (like sulfuric acid regeneration equipment) and chlorine-containing media (like PVC production).
Environmental Field:
Hastelloy C276 square plate is used in flue gas desulfurization (FGD) units, such as scrubbers and flues. It resists sulfides and wet corrosion.
Marine Engineering:
Hastelloy C276 square plate is used in seawater treatment pump and valve components and subsea pipeline flanges. It resists salt spray corrosion.
Energy Industry:
Hastelloy C276 square plate is used in nuclear fuel rod components and high-sulfur oil well parts in oil and gas extraction.
