NI90Cr10, also known as Nichrome 90 or NiCr 90/10, is a high-performance alloy that offers excellent resistance to high temperatures and corrosion. It has a high melting point of around 1400°C (2550°F) and can maintain its strength and stability even at temperatures above 1000°C (1832°F).
This alloy is commonly used in applications that require heating elements, such as in industrial furnaces, ovens, and heating appliances. It is also used in the production of thermocouples, which are used to measure temperature in various industrial processes.
NI90Cr10 has an excellent resistance to oxidation, which makes it particularly useful in high-temperature environments where other materials would quickly corrode and degrade. It also has good mechanical properties, such as high tensile strength and good ductility, which make it easy to form and shape.
When it comes to pipes made of this alloy, they are typically used in applications where high-temperature and corrosive conditions are present, such as in chemical processing, petrochemical, and power generation industries. The specific properties of the pipe, such as its size, wall thickness, and pressure rating, would depend on the intended use and the specific requirements of the project.
