These alloys come in a wide range of sizes and are simple to work with. These alloys can withstand high heat, making them easy to weld into place with minimal effort. Furthermore, they're easy to source and widely recognized for their durability; however, it is essential that you choose the correct grade for each application.

Applications of Hastelloy fasteners

Hastelloy fasteners are widely used in various applications. They're especially ideal for industrial settings where they must resist corrosion, such as chemical processing, oil and gas extraction, power generation and more.

For optimal performance, they must be made from high-grade material that can withstand even the harshest conditions. Fortunately, there are numerous superalloys designed specifically to handle such demands.

One of the most commonly used alloys is Hastelloy C276. This nickel-molybdenum-chromium alloy boasts exceptional resistance to a range of harsh environments, such as acidic, alkaline and chloride-rich areas. Furthermore, it boasts high temperature strength and excellent mechanical properties.

Another popular grade is Hastelloy X. This alloy boasts a high chromium content and exhibits excellent resistance to both oxidation and carburization, as well as pitting and crevice corrosion at elevated temperatures.

Molybdenum provides this grade with enhanced resistance to fatigue and stress corrosion cracking, making it suitable for use in a range of applications. Forged and cold worked, molybdenum offers improved performance properties in various processes.

It is also renowned for its exceptional resistance to corrosive chemicals, such as ferric and cupric chlorides, chlorine, hot contaminated solutions (organic and inorganic), formic and acetic acids, seawater/brine solutions. This makes it an ideal choice in chemical processing industries where upset conditions are frequently encountered.

Due to this property, titanium alloy is often the material of choice when welding joints exposed to harsh chemicals. Furthermore, this alloy resists grain boundary precipitates formation within the weld heat-affected zone, making it suitable for most chemical process applications even in their as-welded state.

Hastalloy fasteners come in an extensive selection of sizes and grades, making it easy to find the right fastener for any application. In addition to standard bolts and nuts, Hastelloy fasteners also come as studs or washers.
