Nickel Alloys (Inconel, Hastelloy) High Pressure Vessels | Roben Manufacturing
Nickel Alloys (Inconel, Hastelloy) for High Pressure Applications
Nickel-based alloys, including the Inconel and Hastelloy families, represent the premier materials for high pressure vessels operating in extreme temperature and corrosive environments. Inconel alloys (600, 625, 718) excel in high-temperature oxidizing conditions, while Hastelloy variants (C-276, C-22, B-2) provide exceptional resistance to aggressive acids and chemicals. These superalloys maintain their strength and corrosion resistance at temperatures where other materials fail, enabling reliable service in the most demanding process conditions.
Why Choose Nickel Alloys (Inconel, Hastelloy)?
Nickel alloys deliver unmatched performance for high pressure vessels facing conditions that would rapidly degrade other materials: temperatures exceeding 1,500°F, exposure to chloride-induced stress corrosion cracking, contact with strong acids and mixed acid environments, and high-temperature hydrogen service. While material and fabrication costs exceed carbon and stainless steels, the extended service life, reduced maintenance, and safety assurance justify the investment in critical applications where failure is not an option.
