Chanathip Nickel Alloys & Plates is a prominent manufacturer and exporter of Hastelloy C276 Bolts in Bangkok, Thailand. These carefully crafted fasteners are fabricated out of high-grade UNS N10276 alloy, which is highly appreciated for outstanding corrosion resistance in hostile environments. Our products are provided in hex, socket head, stud, and special bolt forms and conform to ASTM B574 and applicable international standards. C276 bolts are suited for application in severe chemical processing, marine, and pollution control applications. We offer C276 fasteners with full traceability, MTCs, and strict testing to meet dimension accuracy and mechanical integrity.
Hastelloy C276 bolts consist of ~57% nickel, 15.5% molybdenum, 16% chromium, 4% iron, and trace amounts of tungsten and cobalt. They provide yield strength of about 355 MPa, tensile strength of up to 760 MPa, elongation of ~40%, and hardness ≤100 HRB. The alloy shows superior resistance to oxidizing and reducing substances, such as hydrochloric acid, sulfuric acid, chlorine, and seawater. It shows resistance to pitting, crevice corrosion, and stress corrosion cracking. C276 retains structural integrity in temperatures of up to 1040°C and is thus applicable to high-temperature bolting.

Hastelloy C276 bolts are utilized in chemical reactors, scrubbers, heat exchangers, pressure vessels, and marine equipment where corrosion is the key factor. They are extensively used in chemical processing, pharmaceutical, wastewater treatment, pulp & paper, and offshore industries. C276 fasteners are best suited for joining flanged joints and equipment in highly acidic or chloride-enriched atmospheres. They ensure long-term stability and reduce bolt failure risk in critical systems. These bolts find frequent usage in flue gas desulfurization equipment, incinerators, and digesters, where other alloys get degraded with time.
