A286 Bar and Rod is a high-strength, iron-based superalloy that contains around 15–16% chromium and 25–26% nickel, along with some molybdenum and titanium. This unique blend gives it remarkable resistance to corrosion and oxidation, as well as stability at high temperatures. On the mechanical side, A286 boasts impressive tensile strength, outstanding fatigue resistance, and the ability to perform well in extreme conditions, even up to 700°C (1292°F). Its hardness, toughness, and resistance to creep make it perfect for components that face high stress. Plus, heat treatment can further boost its mechanical properties, making it a dependable choice for demanding industrial uses.

A286 bars are available in various sizes, typically ranging from 1/8" to 12" in diameter. Common finishes include hot-rolled, cold-drawn, polished, and ground, depending on the supplier.
A286 alloy, a high-strength, corrosion-resistant steel, can be susceptible to galvanic corrosion when in contact with more electropositive metals, particularly in saline or corrosive environments. Proper isolation is recommended.
Yes, A286 bar can be welded using appropriate techniques, such as gas tungsten arc welding (GTAW) or gas metal arc welding (GMAW), with proper preheating and post-weld heat treatment to avoid cracking.
A286 Bar and Rod finds its way into industries that need high-temperature strength and corrosion resistance. You’ll often see it in aerospace components like engine parts, turbine shafts, and fasteners, where performance under intense heat and stress is crucial. It’s also a go-to material in automotive manufacturing, especially for high-performance engines and exhaust systems. In the energy sector, A286 is utilized in chemical processing equipment, power generation systems, and oil and gas applications, thanks to its durability in harsh, corrosive environments. Its blend of strength, oxidation resistance, and fatigue performance makes it a standout choice for various demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
