A286 Round Bar
A-286 Stainless Steel Alloy, UNS S66286, A-286 Stainless, Alloy A-286 Stainless Steel, A-286 Alloy, Grade 660, ASTM A638 (VO1.03), A453 (VO1.01), 660B
Our A286 Round Bar is an iron-nickel-chromium superalloy strengthened by titanium and molybdenum additions, designed for exceptional high-temperature strength and oxidation resistance. This precipitation-hardening alloy maintains excellent mechanical properties and structural stability at temperatures up to 1300°F (704°C), making it ideal for aerospace, turbine engine, and high-stress applications where other materials fail. Our A286 round bars are vacuum-melted to ensure superior purity, consistency, and performance in the most demanding conditions.

Main Application Areas
Aerospace
A286 Round Bar Used in the manufacture of high-temperature, load-bearing components such as turbine discs, compressor discs, rotor blades, and fasteners for aircraft engines.
Petrochemical
Used in the manufacture of pipes, valves, and fasteners for high-temperature, high-pressure environments, resisting corrosion from media such as oil and gas, as well as the effects of high temperatures.
Automotive
Commonly used in key components in automotive engines and turbocharger assemblies, improving component performance and service life.
Medical
Due to its excellent corrosion resistance and limited biocompatibility, it can be used in the manufacture of some surgical instruments.
FAQ
Q: What is the maximum service temperature for A286?
A: A286 can be used continuously up to 1300°F (704°C) while maintaining excellent mechanical properties and oxidation resistance.
Q: Can A286 be welded?
A: Yes, A286 Round Bar has good weldability using TIG or MIG methods. Post-weld heat treatment is recommended to restore properties.
Q: How does A286 compare to Inconel 718?
A: A286 offers similar high-temperature strength but at a lower cost, while Inconel 718 provides better corrosion resistance in more aggressive environments.
Q: Do you provide bars in different heat treatment conditions?
A: Yes, we supply A286 bars in solution annealed, precipitation hardened, and aged conditions to meet specific application requirements.
