We produce hastelloy C276 bolts, screws, stud bolts, threaded rods, nuts, washers, dowel pins and custom bolting components. Hastelloy C276 fasteners are critical piping components in many industrial sectors. Due to critical nature of hastelloy C276 application, Boltport uses only fresh bar stock from European, American, Japanese & Korean mills. These fasteners are manufactured with complete material and dimensional compliance to latest industry specifications. Alloy C276 fasteners are available in metric and imperial sizes with ISO, UN, UNC, UNF, UNEF, BSW & BSF threads.
Hastelloy C276 is commonly used in forms of hex bolts, heavy hex bolts, full threaded stud bolts, double end studs, socket head cap screws, set screws, hex, heavy hex nuts, square nuts, plain and spring lock washers, etc. Hastelloy C276 is used for bolting pipeline components, process equipments and instruments in projects associated with chemical and petrochemical processing, power generation, pharmaceuticals, oil & gas extraction and metal/mineral processing fields.
About Hastelloy® C276
Hastelloy C276 is a nickel-molybdenum-chromium alloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. Also known as Alloy C276 The high nickel and molybdenum contents make this alloy specially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition.
Although there are several variations of the Hastelloy nickel alloy, Hastelloy C-276 is by far the most widely used.Alloy C-276 is widely used in the most severe environments such as chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour natural gas.
