Hastelloy C-276 Nickel Base Alloy Sheet Corrosion Resistant Alloy Plate

Overview of Hastelloy C - 276 Nickel Base Alloy Sheet

The Hastelloy C - 276 nickel base alloy sheet is a high - performance corrosion - resistant alloy plate that has gained significant popularity across various industries. This alloy is a product of advanced metallurgical technology, offering a unique combination of properties that make it suitable for some of the most challenging environments.

Chemical Composition

The Hastelloy C - 276 alloy is composed of several key elements. Nickel (Ni) is the base element, accounting for a large proportion, typically around 57%. Molybdenum (Mo) is present at approximately 16%, which enhances the alloy's resistance to pitting and crevice corrosion. Chromium (Cr) at about 15% provides oxidation resistance. Other elements such as iron (Fe), tungsten (W), and cobalt (Co) are also present in smaller but significant amounts. The precise chemical composition is carefully controlled to ensure the alloy meets the strict standards of performance and quality. This well - balanced composition is the foundation for the alloy's excellent corrosion - resistant properties.

Corrosion Resistance

One of the most remarkable features of the Hastelloy C - 276 nickel base alloy sheet is its outstanding corrosion resistance. It can withstand a wide range of corrosive media, including sulfuric acid, hydrochloric acid, and phosphoric acid. In environments with high chloride ion concentrations, it shows excellent resistance to pitting, crevice corrosion, and stress - corrosion cracking. This makes it an ideal choice for applications in the chemical processing industry, where it is often used in reactors, storage tanks, and piping systems that handle aggressive chemicals. In addition, it can also resist corrosion in seawater, making it suitable for marine and offshore applications such as desalination plants and oil rig equipment.

Mechanical Properties

The Hastelloy C - 276 alloy sheet has excellent mechanical properties. It has high strength and good ductility, which allows it to be easily formed into various shapes during the manufacturing process. At room temperature, its tensile strength can reach up to 760 MPa, and the yield strength is around 350 MPa. The alloy also maintains good mechanical properties at elevated temperatures. It can operate at temperatures up to 1093°C (2000°F) without significant loss of strength. This high - temperature performance makes it suitable for applications in the aviation and aerospace industries, where components need to withstand extreme heat and stress.

Manufacturing and Standard Compliance

The Hastelloy C - 276 nickel base alloy sheets are manufactured using advanced rolling and annealing processes to ensure uniform thickness and excellent surface finish. The production process adheres to strict quality control measures and complies with international standards such as ASTM and ASME. These standards ensure that the alloy sheets meet the required chemical composition, mechanical properties, and dimensional accuracy. The sheets are available in various thicknesses, widths, and lengths to meet the diverse needs of different industries.
