What are A286 Alloy?

A super-alloy based on iron called stainless steel A286 is precipitation hard enable. Applications requiring high strength and corrosion resistance up to 1300 °F (700 °C) make use of the substance. In addition, additional A286 Stainless Steel Properties, are superb production capabilities, low-temperature non-magnetic strength (down to -320 °F (-196 °C), and ductility.

Stainless steel is used in a variety of aviation parts, including fasteners, springs, and parts for jet engines. Additionally, the substance is used in non-magnetic cryogenic components, aqueous solutions with minimal corrosion qualities, and industrial gas turbines. In the automobile sector, high-temperature afterburner components, tanks, pipelines, pumps, heat ex changers, and superchargers are further applications.

While A286 is tougher than comparable stainless steels based on nickel or cobalt, it can still be made by cold-drawing and is easily machined. A286 can also be solution annealed or age-hardened according to the application, and further cold-working greatly increases the creep strength.

Application of A286 Alloy

  • Jet engine components
  • Fasteners
  • Springs
  • Bolts
  • Flanges
  • Blades
  • Afterburners
  • Automotive applications
  • Offshore oil & gas
  • Moderate corrosion applications in aqueous solutions
  • Non-magnetic cryogenic equipment

Resistance to Corrosion and Oxidation

Chromium, nickel, and molybdenum content in type A286 alloy is comparable to that of various austenitic stainless sheets of steel. As a result, this alloy has a comparable level of water corrosion resistance to these grades. In applications involving higher temperatures, corrosion resistance is excellent up to at least 1300°F (704°C) in atmospheres like those encountered in jet engine applications. Up to 1500°F (816°C) of continuous use and 1800°F (982°C) of intermittent use, the oxidation resistance is strong.
