Alloy A286 fasteners are engineered for demanding applications where high tensile strength, oxidation resistance, and dimensional stability at elevated temperatures are essential. These fasteners are superior in environments that reach 704 °C (1300 °F) and adhere to the ASTM A453 (Grade 660), ASME B18.2.1, and DIN 975/976 standards. The reliability and performance that critical assemblies require are provided by Alloy A286 components, regardless of whether they are employed in aerospace, gas turbines, offshore platforms, or petrochemical facilities.
Alloy A286 is a robust metal composed of iron, nickel, and chromium, with the addition of molybdenum and titanium. This combination provides alloy A286 with exceptional resistance to corrosion in various environments and exceptional strength against stretching. It is an optimal choice for cryogenic apparatus, turbine wheels, jet engine housings, and exhaust manifolds due to this property. Long service life is guaranteed by its capacity to preserve mechanical properties in the face of cyclical thermal loading, even during the most severe duty cycles.
Our Alloy A286 fastener range covers both metric (M6–M48) and imperial (¼″–2″) thread sizes, including UNC, UNF, and metric coarse/fine series. Standard offerings include hex bolts, hex nuts, socket head cap screws, stud bolts, flat washers, and spring washers. Furthermore, custom machining options are accessible to satisfy unique design specifications, including collars, pins, and turned parts. Optional secondary operations, such as electropolishing or phosphate coating, are available upon request. These finishes include solution annealed, aged (precipitation-hardened), and passivated.
We supply both bulk and project-specific quantities, from prototype runs to production batches exceeding 10,000 pieces. All items are securely packed in export-grade cartons, wooden crates, or sealed poly bags, with clear labeling and mill test certificates included. Our streamlined logistics and warehousing in India ensure short lead times, while our global freight partnerships deliver on time anywhere in the world.
Alloy A286 fastener price varies by size, thread form, and heat treatment, typically ranging from ₹40 to ₹500+ per piece. As a leading Alloy A286 fasteners supplier and stockist in India, Vision Alloys guarantees full material traceability, third-party inspection options, and adherence to the most stringent quality management systems. For applications where conventional alloys fall short, Alloy A286 fasteners offer the strength, stability, and corrosion resistance your project demands.
