Hastelloy C-276 Plates – Industrial-Grade Nickel Alloy for Harsh Environments

Introduction to Hastelloy C-276 Plates
Hastelloy C-276 is a premium nickel-molybdenum-chromium alloy designed to withstand the most corrosive and high-temperature environments. Its superior resistance to oxidizing and reducing agents, localized corrosion, and stress corrosion cracking makes it a top choice for industries dealing with harsh conditions. Hastelloy C-276 plates offer high strength, durability, and exceptional performance, ensuring long service life in extreme applications.

Chemical Composition & Grades
Hastelloy C-276 is classified under UNS N10276 and meets industry specifications such as ASTM B575 and ASME SB575. Its key chemical components include:

Nickel (Ni): 57% min – Provides excellent corrosion resistance
Molybdenum (Mo): 15-17% – Enhances resistance to localized corrosion
Chromium (Cr): 14.5-16.5% – Improves oxidation resistance
Iron (Fe): 4-7% – Adds mechanical strength
Tungsten (W): 3-4.5% – Enhances overall durability
Other Elements: Cobalt (Co), Carbon (C), Silicon (Si), Manganese (Mn) in controlled amounts
Manufacturing Process
Hastelloy C-276 plates undergo strict metallurgical processing to ensure top-notch quality and performance. The key steps include:

Melting & Alloying: High-purity raw materials are melted in a vacuum induction furnace.
Hot Rolling & Cold Rolling: Plates are processed through precision rolling techniques to achieve the desired thickness and mechanical properties.
Solution Annealing & Heat Treatment: The plates are heat-treated at 1100–1150°C (2012–2102°F) to optimize corrosion resistance and mechanical strength.
Surface Finishing & Quality Inspection: Plates are treated with pickling, polishing, or protective coatings and undergo rigorous testing for quality assurance.
Applications of Hastelloy C-276 Plates
Hastelloy C-276 plates are extensively used in industries that require high corrosion resistance and mechanical strength in extreme environments:

Chemical Processing: Ideal for reactors, heat exchangers, and storage tanks handling strong acids (HCl, H2SO4, HNO3).
Marine & Offshore: Used in shipbuilding, seawater desalination plants, and offshore oil & gas platforms due to its excellent seawater resistance.
Power Generation: Applied in flue gas desulfurization (FGD) systems, boilers, and pressure vessels in power plants.
Pharmaceutical & Food Industry: Used in sanitary processing equipment for contamination-free production.
Aerospace & Defense: Suitable for high-temperature jet engine components and structural materials in extreme conditions.
