Hastelloy B2 Fasteners

Vision Alloys is a trusted manufacturer, supplier, stockist, and exporter of premium Hastelloy B2 fasteners, offering reliable fastening solutions for industries that demand superior corrosion resistance and mechanical strength. Based in India, the company supplies high-performance fasteners used in chemical processing plants, petrochemical refineries, power generation facilities, and marine engineering projects. B2 hastelloy fasteners are specially designed to perform in highly aggressive environments where standard stainless steels or other alloys would quickly degrade.

The range of Hastelloy B2 fasteners includes hex bolts, hex nuts, socket head cap screws, machine screws, threaded rods, washers, and stud bolts. All products are made to meet strict global quality standards, such as ASTM B574 for nickel-molybdenum alloys, ASME SB574 for fasteners that can withstand high temperatures and corrosion, and DIN 933 or DIN 934 for metric hex bolts and nuts. Compliance with these precise standards ensures each fastener delivers consistent performance, accurate dimensions, and durability in extreme operating conditions.

Hastelloy B2 Nuts and Bolts are crafted from a nickel-molybdenum alloy containing approximately 65% nickel, 28% molybdenum, and controlled levels of iron, cobalt, and chromium. This mixture provides excellent protection against hydrochloric acid in any amount and at any temperature, as well as against hydrogen chloride, sulfuric acid, and phosphoric acid in specific conditions. B2 fasteners exhibit a tensile strength of around 750 MPa (109,000 psi), a yield strength of 350 MPa (50,800 psi), and an elongation of 40%, making them suitable for high-stress applications. They also maintain stability during welding and fabrication without loss of corrosion resistance.

Vision Alloys offers Hastelloy B2 fasteners in sizes from M3 to M100, with options for both coarse and fine threads like UNC, UNF, BSW, and metric. Customers can choose lengths from short screws to long studs and select surface finishes such as passivation, PTFE coating, or plain finish to meet different needs. They can order standard fasteners or ask for custom-made parts based on their project designs, ensuring a perfect fit and outstanding performance in complex assemblies.
