When the task calls for Hastelloy Fasteners, call for Fasteners And Fixtures.Hastelloy is the registered trademark name of Haynes International, Inc.Hastelloy® fasteners, such as Hastelloy C276 fasteners, are made from nickel-molybdenum-chromium alloy that is generally considered a versatile highly corrosion resistant alloy. Hastelloy fasteners have excellent corrosion resistance in both oxidizing and reducing media which makes it well suited for a variety of strong corrosive applications. Hastelloy fasteners also have exceptional resistance to both sulfuric acid and hydrochloric acid
Because Hastelloy fasteners resist some of the most severe media, Hastelloy fasteners are often utilized in chemical processing applications where acid chlorides, solvents, formic and acetic acids, acetic anhydride, wet chlorine gas, hypochlorites, chlorine solutions and phosphoric acid are used. For chemical processing applications, Hastelloy C276 is the most common grade and one of the most corrosion resistant nickel alloys - exceeding that of most other nickel alloy grades like Inconel or Monel.
We can provide a wide variety of Hastelloy fasteners including; Hastelloy nuts, Hastelloy bolts, sockets, washers and more Hastelloy Fasteners. If we do not have your Hastelloy Fasteners in stock (Inch or Metric) we can have these manufactured to your specification.
Orders at Fasteners And Fixtures are guaranteed fast delivery of the Hastelloy Fasteners in the country. The main reason being we have an excellent warehousing and storage facilities for both finished and semi finished goods.They are made ready as per the urgent requirements of the customers. The Hastelloy Fasteners are manufactured to sustain very high pressure and product warranty.In 2015 we have stocked more than 188 tons of Hastelloy Fasteners in all sizes, to cater to immediate delivery and urgent needs of the clients. For small requirements we can dispatch the Hastelloy Fasteners immediately against the purchase order.

Common Grades of Hastelloy Fasteners
HASTELLOY® C-276 Fasteners
This is the most widely used and versatile, corrosion resistant alloy. Very good resistance to
reducing, and mildly oxidizing corrosives. Excellent stress corrosion cracking resistance with very
good resistance to localized attack.
HASTELLOY® B-2 Fasteners
Excellent resistance to hydrochloric acid and other strongly reducing chemicals but has poor
corrosion resistance to oxidizing chemicals and in the presence of ferric or cupric salts. In
addition, Hastelloy B2 has excellent resistance to pitting and stress corrosion cracking
HASTELLOY® C-22 Fasteners
Better overall corrosion resistance in oxidizing corrosives than C-4, C-276 and 625 alloys.
Outstanding resistance to localized corrosion and excellent resistance to stress corrosion cracking.
This alloy has limited availability and can be made into fasteners in larger diameters only. larger
sizes only (1/2" and greater is size).
HASTELLOY® C-2000 Fasteners
Most versatile, corrosion resistant alloy with excellent resistance to uniform corrosion in oxidizing or re-ducing environments. Excellent resistance to stress corrosion cracking and superior resistance to localized corrosion as compared to C-276 alloy. This alloy has limited availability and can be made into fasteners in larger diameters only. larger sizes only (1/2" and greater is size).
