ToggleIn various types of industry, such as chemical processing, oil and gas, pharmaceutical, and power generation, Hastelloy alloys in general are considered to be the most trusted and reliable corrosion-resistant materials. Among the popular grades of Hastelloy, Hastelloy C276 presents the fastest performance under severe environments. Within this blog, we will discuss the benefits, types, and applications of Hastelloy fasteners, including bolts, nuts, screws, washers, and studs in the form of Hastelloy C276.
Hastelloy C276 is a nickel-molybdenum-chromium alloy with an added amount of tungsten. Its versatility and resistance to several corrosive media account for its usage in strong oxidizers like ferric and cupric chlorides, hot contaminated organic and inorganic media, and acidic solutions.
UNS Designation:
UNS N10276 for Hastelloy C276
UNS N6022 for Hastelloy C22
UNS N10665 for Hastelloy B2
UNS numbers help to identify and standardize the specific composition of each alloy.
The Hastelloy range of fasteners is vast to cater to all types of industries. Some of the most common include
Hastelloy C276 Bolts: These bolts have high strength and corrosion resistance. It is used at high temperatures and very aggressive chemical environments. As such, it can be commonly found in reactors, pressure vessels, and heat exchangers.
Hastelloy C22 Nuts: These nuts provide outstanding protection against oxidation and pitting. Thus, they are highly suitable for fluctuating temperatures and corrosive chemicals.
Hastelloy B2 Screws: Providing corrosion resistance at a high level in a reducing environment like hydrochloric acid, hastalloy B2 screws are used for industries involving acid processing.
Hastelloy C276 Washers: The washers made from Hastelloy C276 offer a secondary degree of resistance against corrosion besides helping in distributing loads evenly so that bolted joints are reliable as well as durable.
Hastelloy C22 Studs: Any environment where oxidation and corrosion must be controlled, the Hastelloy C22 stud offers durability with long-term performance.
These fasteners can be designed specific to requirements as to thicknesses and sizes, making them versatile and adaptable to any application.
Hastelloy fasteners are applied in many applications because they can withstand extreme conditions. Some significant applications involve:
Chemical Processing Industry: Hastelloy fasteners are widely used for resistance to both acid and bases. It is used in reactors, distillation columns, and piping systems.
Oil and Gas Industry: Hastelloy C276 and C22 fasteners are used offshore and onshore facilities when the high operating temperatures and sour gas corrosive environment occurs in fields.
Pharmaceutical Industry: Hastelloy fasteners ensure that the pharmaceutical products are not contaminated and are sterile, as they have a high resistance to corrosive cleaning agents and solvents.
Power Generation: In nuclear and fossil fuel-based power plants, Hastelloy fasteners facilitate the management of high fuel temperatures and corrosive chemicals used, which makes the overall power generation system safer and efficient.
Corrosion Resistance: Hastelloy C276, C22, and B2 fasteners are highly corrosion-resistant and are, therefore, suitable for application in aggressive chemical conditions.
Strength: Fasteners of Hastelloy retain their mechanical strength even under high-temperature conditions, providing structural integrity under demanding conditions.
Versatility: Hastelloy fasteners can be made in the application-specific requirements, with thickness and size variation as per specific requirements.
Durability: Hastelloy fasteners, having robust formation, have a more extended service life. Therefore, reduction in the frequency of replacement and maintenance results.
Hastelloy fasteners include Hastelloy C276 bolts, Hastelloy C22 nuts, and Hastelloy B2 screws, amongst others, to offer superior resistance against corrosion and high-strength withstand along with durability. These are integral components used in various sectors including chemical processing, oil and gas, pharmaceutical, and power generation.
