Ni resist castings manufacturers.
Ni-Resist is a family of austenitic cast iron alloys that are known for their excellent resistance to corrosion and high-temperature oxidation. Ni-Resist castings are used in various industries where the castings are exposed to acidic or corrosive environments, such as chemical processing, marine, and power generation.
Ni-Resist castings are composed of alloying elements such as nickel, chromium, and silicon, which provide excellent corrosion resistance and high-temperature strength. The nickel content in Ni-Resist castings ranges from 14% to 36%, providing increased resistance to high-temperature oxidation.
The casting process for Ni-Resist involves melting the metal in a furnace, pouring it into a mold, and allowing it to solidify. Ni-Resist is a highly fluid metal, meaning that it can be poured into intricate molds without the risk of shrinkage or cracking.
Once the casting has solidified, it is machined into its final shape. Ni-Resist castings are known for their excellent machinability, which allows for precision finishing and tight tolerances.
Ni-Resist castings have many applications, including pump and valve components, chemical reactors, and exhaust manifolds. They are also used in marine applications, where the metal's resistance to seawater corrosion is necessary.
Overall, Ni-Resist castings offer excellent resistance to corrosion and high-temperature oxidation, making them an essential material for many industries.
