TECHNICAL INFORMATION FOR A286 PER AMS 5858
A286 per AMS 5858 is a corrosion-resistant and heat-resistant stainless steel, which is available in sheet, strip, and plate form. It is a precipitation hardenable iron-nickel-chromium alloy with the composition of chromium, nickel, molybdenum, titanium, boron, and vanadium.
The alloy has to go through a number of melting operations and a solution heat treatment at 1800 °F (980 °C) to provide the alloy with high-temperature properties and solid oxidation resistance. The alloy is generally supplied in the unaged condition, which makes it suitable for welding applications.
Fighter Jet Metals offers AMS 5858 in the form of plate, sheet, and strip.
WELDING CHARACTERISTICS
A key advantage of A286 per AMS 5858 is its excellent weldability. Because the alloy is not aged prior to fabrication, the risk of cracking during welding is reduced.
Common welding methods include:
- Gas Tungsten Arc Welding (GTAW)
- Gas Metal Arc Welding (GMAW)
- Shielded Metal Arc Welding (SMAW)
For optimal results, weld beads are typically applied with a slightly convex profile to improve joint strength.
Applications of AMS 5858
A286 per AMS 5858 is widely used in industries requiring heat resistance, strength, and weldability, including:
- Aerospace structural components
- Aircraft engine assemblies
- Turbine components
- High-temperature sheet metal parts
- Industrial heat-resistant equipment
