Hastelloy Bolts, Screws, Nuts & Washers
Hastelloy Fasteners offer outstanding corrosion resistance to a vast number of corrosive chemicals, for use in a wide range of severe and demanding environments. Hastelloy, a collection of Nickel-Chromium-Molybdenum based superalloys, exhibits various properties depending on the grade and chemical composition. These fasteners are typically supplied in:
Often referred to as Alloy C-276 or UNS N10276, this grade is composed of 57% Nickel, 16% Chromium and 16% Molybdenum. It is ductile and provides great resistance to stress corrosion cracking, crevice corrosion and pitting. The high quantities of Chromium and Molybdenum enable high resistance to oxidising and non-oxidising agents – an ideal choice for chemical processing and offshore applications.
Alloy C-22 or UNS N06022 is considered an improved version of C-276, offering greater versatility and better overall corrosion resistance. Made up of 56% Nickel, 22% Chromium and 13% Molybdenum, C-22 has a slightly higher melting point of 1399°C and an increased Chromium content. This provides greater resistance to oxidising agents compared to other grades – significantly improving the lifespan of these Hastelloy Fasteners.

Hastelloy Screws, Fasteners and Fixings
Hastelloy is a nickel-molybdenum alloy available in a number of different grades – each of which is optimised for a specific purpose. Whilst the different grades are optimised specifically, they all are highly resistant to corrosion – making them perfect as a fixing material.
It is a high-performance alloy and belongs to the “superalloy” family alongside Incoloy.
The molybdenum addition gives Hastelloy a number of exciting benefits, such as making it harder and stronger at high temperatures.
It is great for applications like welding and can be easily fabricated and formed due to good ductility and the fact it can be forged and cold worked.
Hastelloy fasteners have high resistance to uniform attack and localised corrosion resistance.
We supply fasteners in various grades of Hastelloy here at Fastenright, including Hastelloy C4, Hastelloy C22 and Hastelloy C276.
