Hastelloy C4-C22-C276 fasteners are fasteners that are very well known for their highly corrosive-resistant properties. It is a fastener that is an alloy that is made up of nickel and molybdenum. Hastelloy C4/C22/C276 fasteners possess various properties, such as being anti-corrosive and resistant to pitting and corrosion cracking.


Hastelloy C4 Concrete fasteners has a very close resemblance to alloy c, which has excellent welding properties and can withstand an environment that can cause oxidation. Therefore these can be used in seawater applications and environments where they could be subjected to various chemicals. They are used in multiple industries, including the chemical industries, the oil industry, the different pulp and paper industries, etc. Exposure of Hastelloy C22 Socket Set fasteners at over 1250 degrees Fahrenheit is not suggested as it could lead to dangerous formations that might get caused.

They can come in various shapes and sizes depending upon the user's specifications. In addition to being corrosion-resistant, these also can be fabricated and are also weldable. Hastelloy C276 Threaded fasteners possess this property because of the nickel content present in them. Nickel alloys usually are more accessible to shape into various forms and sizes and are very malleable, unlike the others. The chromium and molybdenum nature is responsible for the property that allows C276 Hastelloy Countersunk Bolt to stand in multiple thermal conditions and acidic environments.
