AISI 660 / Alloy A-286

AISI 660 / Alloy A-286 / 1.4980 / UNS S66286

AISI 660, also known as Alloy A-286, is a nickel-iron-chromium alloy with additions of molybdenum, titanium, and vanadium, specifically designed for applications under extreme temperatures and mechanical stress. The alloy combines high strength, heat resistance up to 700°C, excellent creep and oxidation resistance, and good weldability and machinability, making it a reliable choice for critical components in demanding sectors.

Thanks to these properties, Alloy A-286 delivers long-lasting performance in environments where other alloys fall short.

Properties of AISI 660 / Alloy A-286

Alloy A-286 stands out due to an excellent combination of mechanical strength, thermal stability, and corrosion resistance. The alloy maintains its structure and performance up to 700°C, with high tensile and creep resistance under prolonged stress.

The addition of titanium and vanadium provides precipitation hardening, enhancing strength and fatigue resistance. Furthermore, the material offers good resistance to oxidation and corrosion in both air and aggressive industrial environments. Alloy A-286 is also highly weldable and machinable, facilitating its application and workability.

These properties make the alloy suitable for structural applications in aerospace, energy, automotive, and chemical processes.
