Resistant To High Temperature And Pressure Hastelloy C22 Strip Ni Cr Mo 45% Elongation For Energy Industy

Product Introduction

Hastelloy C22 strip is a high-performance nickel-based alloy strip with a wide range of applications in the energy sector. Its main chemical components include nickel (balance), chromium (20.0-22.5%), molybdenum (12.5-14.5%) and tungsten (2.5-3.5%), which give it excellent corrosion resistance and high-temperature stability. Hastelloy C22 strip has a density of 8.69 g/cm³, a melting point of about 1300-1350°C, and can maintain excellent performance in environments up to 1000°C.
In the energy field, Hastelloy C22 strip is widely used in the manufacture of high-temperature components in solar and wind energy equipment, and can withstand high-temperature corrosion and oxidation. In addition, it is also used to manufacture components in nuclear reactors, and can maintain good performance in extreme environments such as high-temperature and high-pressure water corrosion. The corrosion resistance of Hastelloy C22 strip enables it to effectively resist corrosive media such as coal, oil and natural gas generated in the energy production process, and is used to manufacture energy production equipment, pipelines and storage tanks.

Specific Applications

1. Nuclear reactor components: Hastelloy C22 strip is used to manufacture key components in nuclear reactors, such as fuel element shells, coolant pipes, etc. These components need to operate stably for a long time under high temperature, high pressure and strong radiation environments. The excellent corrosion resistance and high temperature stability of Hastelloy C22 strip make it an ideal choice.
2. Steam generator: In the steam generator of a nuclear power plant, Hastelloy C22 strip can be used to manufacture heat transfer tubes and other key components to ensure the long-term stable operation of the equipment in a high temperature and high pressure water environment.
3. Collectors and heat exchangers: In solar thermal power generation systems, collectors and heat exchangers need to operate in high temperature environments. The high temperature stability and corrosion resistance of Hastelloy C22 strip make it an ideal material for manufacturing these components.

Advantages and Characteristics

• High temperature stability:Hastelloy C22 strip still maintains good mechanical properties and corrosion resistance in high temperature environment, and can operate stably for a long time under high temperature conditions above 800 degrees Celsius. Its face-centered cubic lattice structure and high nickel content make it perform well in high temperature oxidizing environment.
• Resistance to stress corrosion cracking:Hastelloy C22 strip has excellent resistance to stress corrosion cracking, can remain stable in high stress and corrosive environment, and reduce equipment failure rate and maintenance cost.
• Good welding performance:Hastelloy C22 strip has good welding performance and can be welded by various welding processes, such as tungsten electrode inert gas shielded welding, plasma arc welding, manual sub-arc welding, metal inert gas shielded welding, and melt inert gas shielded welding. Before welding, the material needs to be annealed, and the oxide scale, oil stains and various marking marks need to be removed. The width of about 25mm on both sides of the weld needs to be polished to a bright metal surface.
