China Manufacturer of UNS N10276 bolt,Hastelloy C276 hex C276 hex bolt
A UNS N10276 hex bolt, commonly known as a Hastelloy C276 hex bolt, is a fastener made from a nickel-molybdenum-chromium alloy with outstanding resistance to corrosion in a wide range of severe environments. These bolts are primarily used in applications requiring exceptional resistance to oxidizing and reducing agents, making them suitable for chemical processing, marine, and high-temperature environments.
Hastelloy C276 material can be described as a wrought alloy, which highly resists corrosion. The alloy resists the formation of grain boundary precipitates which reduces the corrosion resistance properties. The Hastelloy C276 Fasteners are used in different environments, starting from oxidizing to reducing surroundings. It also offers an excellent resistance to sulfur compounds, and hence Nickel Alloy C276 Hex Bolts can easily be used in flue gas desulphurization systems.
Which is why it is important that an appropriate material such as the Hastelloy c276 bolts is used to build the equipment. Selecting a corrosion resistant material is like making a huge investment for ore processing equipment. What better than choosing nickel based Hastelloy c276 stud bolts! Whether resistance to pitting or to localized corrosion, the Hastelloy c276 nuts proves to be a well favoured choice across many ore processing plants.
Typically during the processing of various mineral ores, there is always a presence of thiosulfates, which in turn leads to small holes or deformities in conventionally used alloys. This is a major concern with ore processing. The ability of Hastelloy c276 forged rings to withstand harsh chemical environments is what makes this alloy an ideal material for ore processing equipment. A technique of extracting ores is Leaching, where the ore is treated with chemicals in order to convert the valuable metals into soluble salts while impurity remains insoluble. ASTM B574 UNS N10276 stud bolt used in this equipment is used to being a part of an oxidative leaching process.
In fact, these Hastelloy c276 fasteners can be used in oxidizing atmospheres up to a temperature of 1900°F. Moreover, the performance of Hastelloy c276 hex bolt tends to be excellent in high pressured environments. For instance, in the acid leaching process, the ASTM B574 bolts perform well at a pressure of about 5400 kPa. However, in environments that are strongly oxidising, the DIN 2.4819 bolt is susceptible to being attacked.
