To satisfy our clients needs by providing high quality products at competitive price as per the schedule and to maintain long term relationship with our clients.
Nickel (57% min), molybdenum (15–17%), chromium (14.5–16.5%), iron (4–7%), and trace amounts of tungsten, cobalt, and vanadium make up the majority of Hastelloy C276 Bolts. One of the most adaptable corrosion-resistant alloys, this composition offers exceptional resistance to oxidising and reducing agents. The bolts have an approximate elongation of 40–45%, a yield strength of 283 MPa, and a tensile strength of 690 MPa. Hastelloy C276 is perfect for demanding process environments because it retains exceptional mechanical strength and corrosion resistance under a variety of chemical exposures and temperatures.
When other materials fail in extremely corrosive environments, Hastelloy C276 bolts are frequently utilised. Key industries include chemical processing, marine engineering, pharmaceutical manufacturing, nuclear fuel reprocessing, and wastewater treatment. These bolts are perfect for attaching parts to equipment that is exposed to harsh chemicals like nitric, sulphuric and hydrochloric acids, such as heat exchangers, evaporators, flue gas scrubbers and reactors. They are also appropriate for offshore and high-temperature systems due to their exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. Punit Fasteners provides precise and dependable C276 bolts that are designed to satisfy particular engineering and environmental requirements.
