The Most Common Types Of Hastelloy Fasteners

Hastelloy Fasteners are high-strength alloy steels designed to be both stronger and lighter, but the alloys also contain additional materials such as vanadium and chromium. Nickel and molybdenum are often ingredients in alloy steels. As alloy steels, Hastelloy C276 Fasteners are designed to have exceptional properties at high temperatures, making them ideal for industrial applications where large amounts of physical stress are present during manufacturing.

There are steel rivets type of Hastelloy fasteners that are used to connect metals together. As well as being used for heavy-duty applications such as ships, trains, and elevators, Hastelloy fasteners can also be used during processing, forging, and welding.

The corrosion-resistant properties of Hastelloy make it ideal for use in harsh environments like chlorine gas and saltwater. This means that it will prevent damages to the pipes and valves from harmful chemicals.

Types of Hastelloy Fasteners

Hastelloy B3: Adaptable to Hydrochloric Acid

With the help of Hastelloy B3 fasteners, the industrial sector now has a material that can withstand all concentrations and heating value of hydrochloric acid. Additionally, B3 has better thermal stability than other B-type alloys, reducing fabrication and welding difficulties.

Hastelloy C22: Oxidizes in Oxidizing Environments

Not all Hastelloy grades can withstand an oxidizing environment, even though they are known for their corrosion resistance. C22 is special because it can defend against strong oxidizers such as ferric acids, cupric chlorides, and nitric acid. Additionally, C22 exhibits greater resistance to pitting caused by chloride as well as conditions of saturated wet chlorine than C276.

Hastelloy C276: Adaptable

The Hastelloy grade utilized for bolting is by far C276 is renowned for offering excellent defense against a variety of acids, including those with moderate oxidizing and severe reducing conditions. Hastelloy 2.4819 Fasteners exhibit excellent resistance to salt water conditions, particularly crevice attack, pitting, and stress corrosion cracking, while being most frequently employed for its resistance to hot acids. Due to its widespread use, Hastelloy C276 is accessible in practically any size, but B3, C22, and C2000 may not be as widely accessible, especially in sizes smaller than 12.

Hastelloy C2000: Exceptional Resistance

With its high molybdenum percentage of C276 combined with the high chromium content of C22, C2000 is an excellent corrosion-resistant alloy that is both effective in reducing and oxidizing conditions. The C2000 will offer improved corrosion protection for processes containing ferric ions and sulfuric acid.
