Alloy 660 Angles & Channels is a precipitation hardening austenitic stainless steel known for its impressive strength at high temperatures up to 700°C. Also sold under the names, UNS S66286, and A-286 alloy, Alloy 660 Angles & Channels gains its strength from a high degree of uniformity. It has an impressive yield strength minimum of 105,000 psi and is commonly used in high temperature fastening and bolting materials. Other applications for Alloy 660 Angles & Channels include:

  • Jet engines
  • Gas turbines
  • Turbo charger components
One thing to note about Alloy 600’s chemical composition is that due to its high nickel content for a stainless steel, it often categorized as a nickel alloy, thus the A-286 label.

Applications

  • Aerospace – piston engine manifolds
  • Chemical Processing
  • Expansion Joints
  • Food Processing – equipment and storage
  • Petroleum Refining – polythionic acid service
  • Waste Treatment – thermal oxidizers

Benefits

  • Higher creep stress and rupture properties when compared with 304
  • Ideal for high temperature service
  • Overcomes sensitization and intergranular corrosion concerns
  • Can be used in elevated temperature applications for ASME Boiler and Pressure Vessel Code applications
  • Excellent mechanical properties
