Ultra-High-Temperature Alloy X Nickel Sheets

- Yield Strength: 54,000 psi
- Temper Rating: Softened (Annealed)
- Specifications Met: ASTM B435, SAE AMS5536
- Hardness: Rockwell B90 (Medium)
Even in temperatures up to 2000° F, Alloy X nickel offers good strength and weldability, along with excellent oxidation resistance. It's often used for components in gas turbine engines and furnaces. This material is equivalent to Inconel HX and Hastelloy X.

Ultra-High-Temperature Thermally Stable Haynes 230® Nickel Sheets

- Yield Strength: 50,000 psi
- Hardness: Rockwell B100 (Hard)
- Temper Rating: Softened (Annealed)
- Specifications Met: ASTM B435
Strong, corrosion-resistant, and stable for long-term use at up to 1800° F, these Haynes® 230 nickel sheets are often used in furnaces and heat-treatment facilities. Containing tungsten and molybdenum for strength, they can be up to 75% thinner than other high-temperature alloy sheets while achieving the same load-bearing capacity. They’ll also last up to 100 times as long as other high-temperature alloys, such as stainless steel and nickel alloys. They’ll resist corrosion in extreme heat, even from harsh chemicals such as sulfuric and hydrochloric acid. Haynes 230® nickel can be used in environments for nitriding—a process used to make steel more corrosion resistant—without being damaged. It’s easily welded, and retains its properties after welding and reshaping.
