Alloy 660 Nuts & Bolts 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 Nuts & Bolts 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 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
