321Stainless Sheets 1/4in, AMS 5513, High Strength, Aerospace Structural Parts

321 stainless steel sheet (1/4in / 6.35mm thickness) is a titanium-stabilized austenitic alloy engineered for high-strength, high-temperature aerospace applications. Compliant with AMS 5513, this sheet offers exceptional resistance to oxidation, creep, and intergranular corrosion, making it ideal for critical structural components in aircraft and spacecraft. The addition of titanium (≥5× carbon content) prevents carbide precipitation during welding or prolonged exposure to 425–860°C, ensuring long-term durability in jet engines, exhaust systems, and airframe structures. Its superior mechanical properties and AMS certification guarantee compliance with stringent aerospace safety and performance standards.
