Copper Nickel Pipe Industry Nickel Based Alloy Incoloy 800 Tube 690 MPa
Product Introduction
Incoloy 800 tube is a high performance nickel-based alloy tube with excellent high temperature corrosion resistance and good mechanical properties, widely used in the power industry. Its main chemical components include nickel (Ni) 30-35%, chromium (Cr) 19-23%, iron (Fe) balance, etc. These components give it excellent oxidation and corrosion resistance at high temperatures. The physical properties of Incoloy 800 tube include density 8.0 g/cm³, melting point 1350-1400°C, tensile strength 450 MPa, yield strength 180 MPa, and elongation 30%. This alloy pipe can still maintain good mechanical properties and anti-oxidation properties in high temperature environments, and is suitable for manufacturing boilers, heat exchangers, steam generator pipes and other equipment in the power industry. Its good processing and welding properties enable it to be formed through conventional processing technology, making it suitable for manufacturing parts with complex structures. Incoloy 800 tube is strictly implemented in accordance with ASTM B407, B514, B515 and other standards, ensuring its stability and reliability in high temperature and high pressure environments. In the power industry, Incoloy 800 tube can significantly improve the service life and operating efficiency of equipment and reduce maintenance costs. It is an indispensable and important material in power production.

Specific Applications
- Superheater and reheater tubes: In thermal power plants, superheaters and reheaters are used to heat steam to a higher temperature to improve power generation efficiency. Incoloy 800 tubes can maintain stable performance at high temperatures, have good oxidation resistance and creep resistance, and are suitable for manufacturing superheater and reheater tubes.
- Nuclear reactor cooling pipes: In nuclear power plants, the cooling pipes of nuclear reactors need to withstand high temperature, high pressure and radiation environments. Incoloy 800 tubes have good corrosion resistance and oxidation resistance, which can meet the use requirements of nuclear reactor cooling pipes and ensure the safe operation of nuclear power plants.
Advantages and Characteristics
- High strength and toughness: Incoloy 800 pipe has a tensile strength of at least 520 MPa, a yield strength of at least 205 MPa, and an elongation of at least 30%.
- Good ductility: With good ductility, it is easy to process and form, and is suitable for various processing processes such as forging, hot rolling, cold working and welding.
- Good machinability: Incoloy 800 pipe can be processed and formed by a variety of traditional methods, such as casting, forging, rolling and welding. Although the alloy is easily work-hardened, it can be successfully spun, deep drawn, pressed or punched after proper treatment.
- Excellent weldability: Incoloy 800 alloy is easy to weld, and the welded joints show excellent corrosion resistance and mechanical properties. No solution treatment is required after welding, which simplifies the processing process and reduces manufacturing costs.
