### **Product Introduction: Alloy A-286 / Incoloy A-286 Fittings** **Superior Performance in High-Temperature and Corrosive Environments** Alloy A-286, also known as Incoloy A-286, is a premier iron-nickel-chromium based superalloy known for its exceptional high-temperature strength, excellent oxidation resistance, and good corrosion resistance. It is a precipitation-hardening austenitic alloy, meaning it can be heat-treated to achieve significantly higher strength levels compared to standard stainless steels. Our **Incoloy A-286 Fittings** are precision-engineered to provide reliable performance in the most demanding applications, including aerospace, gas turbines, and industrial heating. They offer superior creep and stress-rupture properties at temperatures up to 1300°F (704°C), making them the ideal choice for critical high-temperature piping and instrumentation systems. --- #### **1.
