Vision Alloys is a trusted manufacturer, supplier, and exporter of Hastelloy B2 fasteners, providing top-quality solutions for industries that demand superior corrosion resistance. Based in India, our area of expertise is providing high-performance fastening materials resistant to hostile chemical conditions, hence perfect for use in the chemical processing, petrochemical, and maritime sectors.
Our range of B2 Hastelloy fasteners includes bolts, nuts, washers, screws, and studs, which are meant to provide outstanding resistance against hydrochloric acid and other highly reducing surroundings. As a leading Hastelloy B2 fastener manufacturer, by use of ASTM, ASME, and DIN criteria, we guarantee that our products satisfy dependability and durability in demanding environments.
Hastelloy B2 fasteners are more resistant to pitting, stress corrosion cracking, and oxidation because they contain nickel, molybdenum, iron, and small amounts of cobalt and chromium. Tensile strength of 750 MPa, yield strength of 350 MPa, and 40% elongation make these fasteners fit high-stress uses.
With varied threading choices to fit certain industry demands, we provide Hastelloy B2 bolt nuts and washers in a range from M3 to M100. Precision-engineered fasteners from us guarantee a long-lasting and secure fit in severe industrial settings.
At Vision Alloys, our main emphasis is on offering globally exportable, reasonably priced, premium-quality Hastelloy B2 fasteners. Our products guarantee outstanding performance in demanding chemical environments by means of thorough quality inspections meant to satisfy the highest industry requirements.
