Alloy A286 Fasteners, ASTM A453 Grade 660

AISI 4130 Bolts

Alloy 286 fasteners falls under stainless steel fasteners with superior corrosion and oxidation resistance along with high mechanical strength at elevated temperatures and greater aesthetic appearance than 300 class stainless steel. Boltport offers Alloy A286 bolts, screws, stud bolts, studs, threaded rods, nuts, washers and other custom bolting parts in accordance to ASTM A453 Grade 660 specification. We manufacture these A286 fasteners with aerospace precision to withstand extreme operational constraints. We can offer stress rupture test for these A286 (grade 660) bolting.

Alloy A286 is an age hardenable, iron-nickel-chromium alloy, suitable for applications that requires combination of high strength, resistance to oxidation and corrosion at high service temperatures. Alternatively called as Incoloy Alloy A286 can effectively resist corrosion and maintain strength at temperatures upto 1300 deg fahrenheit or 704 deg celcius and resist oxidation upto 1800 deg fahrenheit or 982 deg celcius. The high strength and excellent fabrication characteristics of alloy A-286 make the alloy useful for various components of aircraft and industrial gas turbines. It is prominently used for bolting applications in automotive engine and manifold components subject to high levels of heat and stress and in the offshore oil and gas industries. ASTM A453 is the commonly referred specification for manufacturing Alloy A286 Fasteners under Grade type 660.
