Majid fasteners is a prominent producer and distributor of high-performance industrial fasteners in Dubai, UAE, as well as a dedicated firm to provide quality, accuracy and reliability of its products unparalleled. Our high quality products include Hastelloy C276 Bolts that are designed to be highly corrosion resistant and durable and have a successful performance in environments of the most extreme corrosion and extreme temperature. These bolts are used in long-term applications in chemical processing, offshore, and petrochemical applications, which have long integrity and safety. We offer fastening solutions with modern manufacturing experience, quality control, and that is higher than the expectations of the industry.
Hastelloy C276 Bolts are made up of nickel (Ni), chromium (Cr), molybdenum (Mo), with small quantities of tungsten (W) and very low levels of carbon (C). This alloy provides excellent resistance to pitting, crevice corrosion, and SCC in both oxidising and reducing environments. In addition to its excellent corrosion-resistant properties, Hastelloy C276 Bolts also have superior mechanical properties such as: high tensile strength, high yield strength, good ductility, and superior performance at elevated temperatures. They also support high levels of structural integrity under pressure and thermal stress, giving them long-term reliability in the chemical processing, offshore, and very harsh industrial environments.

Hastelloy C276 bolts are a highly preferred material in the following types of industries: chemical processing plants that deal with very aggressive acids, chlorides and oxidisers; petrochemical and oil/gas refineries, pipelines, reactors and offshore drilling rigs where wheather conditions can be harsh; power generation from coal, oil or gas-burning; pollution control equipment; desalination plants; and any application where there is a combination of hot, wet, and corrosive conditions. Due to their excellent resistance to pitting, long service life, and thermal stability, Hastelloy C276 bolts provide users with maximum safety and durability when fastening together components in high-pressure/temperatures and extremely corrosive conditions.
