345MPA Yield Strength Hastelloy C276 Strip Nickel Alloy Foil With Good Mechanical Properties

Product Introduction

Hastelloy C276 strip is a nickel chromium molybdenum super nickel alloy belt with tungsten added. It is designed for excellent corrosion resistance in a wide range of harsh environments. This alloy is famous for its excellent corrosion resistance, especially in strong acid and high temperature environment. Its chemical composition includes at least 57% nickel, 15.0-17.0% molybdenum, 14.5-16.5% chromium, 4.0-7.0% iron and 3.0-4.5% tungsten. Hastelloy C276 strip has excellent resistance to corrosive media in oxidizing and reducing environments at room temperature, and can still maintain high strength and corrosion resistance at high temperatures up to 1093 ° C. It is widely used in chemical processing, oil and natural gas, pharmaceutical and other industries, as well as in the manufacture of reactors, heat exchangers and piping systems for the treatment of corrosive chemicals such as acids and chlorides. In addition, Hastelloy C276 strip has good processability and weldability. It can be processed by conventional methods and welded by TIG, MIG and other methods to ensure th

Specific Applications

1. Chemical and petrochemical:It is used to manufacture components and catalytic systems in contact with chlorinated organics, as well as equipment and components in corrosive environments such as high temperature, inorganic acids and organic acids mixed with impurities (such as formic acid and acetic acid). It is commonly used in reactors, heat exchangers, evaporators and piping systems in the production of sulfuric acid, hydrochloric acid, phosphoric acid and other strong acid environments.
2. Environmental protection:In the flue gas desulfurization system, it is used to manufacture the discharge pipe and other key components to deal with the complex corrosive environment containing sulfuric acid and chloride.
3. Paper industry:It is used to manufacture digestion and bleaching containers and other equipment to cope with high temperature and high concentration chloride corrosion environment.
4. Ship and offshore engineering:Because of its good seawater corrosion resistance, it is widely used in the field of shipbuilding and marine engineering, such as manufacturing seawater desalination equipment, marine platforms, etc.
5. Aerospace:It is used to manufacture engine components, combustion chamber lining and other key components in high temperature operation environment.

Advantages and Characteristics

1. Excellent corrosion resistance:It performs well in complex working conditions where strong acids, strong oxidants and reductants coexist, especially in environments containing chlorides and oxidizing acids.
2. It can resist the corrosion of strong oxidants such as chlorine and nitric acid, and has excellent corrosion resistance in reducing acids (such as hydrochloric acid, sulfuric acid, etc.).The corrosion rate in 6% hydrochloric acid solution after 24 hours is only 0.005 mm/year, which is significantly lower than that of other alloy materials.
3. Good processability:Although Hastelloy C276 has strong mechanical properties, it still has good machinability and can be formed by common cold processing and hot processing.The welding performance is ideal, which is suitable for manufacturing equipment and pipelines with complex structures.
4. High temperature performance:It can maintain good mechanical properties and corrosion resistance at high temperature. The chromium and tungsten elements in the alloy not only improve the high temperature strength, but also enhance the oxidation resistance of the alloy.Able to cope with harsh working environments with temperatures up to 1000 ° C.
5. Mechanical properties:It has high yield strength, tensile strength and ductility, and can withstand the load under high temperature and high pressure environment to avoid the failure caused by material fatigue.
