What are Hastelloy C276 fasteners?
UNS N10276 fasteners are nickel-based alloys that contain tungsten in trace quantities. Regarded as a premium alloy, the Hastelloy C276 Fasteners have excellent corrosion resistance properties – especially in oxidative and reductive environments.
What are standards for alloy C276 fasteners?
Alloy C276 may be used to produce fasteners in the following standards –
ASTM B574, ASTM B575, ASTM F467 (Nuts), ASTM B462, ASTM F468 (screws, bolts, studs), ASTM G28-A/B, ASME B18.2.2, ASTM B619, ASME SB619, ASTM B366, ASME SB366, ASME SB574, ASME B16.11, ASTM B564/ASME SB564, ASME SB575, ASME B16.9, ASME B16.5, ASME SB462
How do you calculate Hastelloy C276 bolts torque?
The following equation may be used to calculate the torque of bolts –
T = KFd(1 – l/100)
Here –
T is the wrenching torque (Nm, lbf ft)
K is the constant that depends on the bolt material and size
d is the nominal bolt diameter (m, ft)
F is the axial bolt force (N, lbf)
l is the lubrication factor (%)

How to measure alloy C276 socket head cap screw size & length?
The length of a alloy C276 socket head screw is measured from the head to the end of its threaded shank. The diameter of its head can be measured from one end to the other.
Applications of Hastelloy C276 hex bolts
The fasteners are used in waste treatment plants where they are exposed to elevated temperatures by incinerators and toxic waste. UNS N10276 bolts are used in sour gas service equipment in the oil and gas industry. Other sectors that use these corrosion-resistant fasteners include – the paper industry, flue gas desulfurization systems, chemical processing units, and the production of pharmaceuticals.
