Nickel Alloy Tubes 825 • UNS N08825 • 2.4858

Short Description:

Alloy 825, often referred to as Incoloy 825 (where Incoloy is a trademark of Special Metals Corp), is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium (NiCr21Mo), supplied in the hot worked and annealed condition. The alloy achieves good mechanical properties from cryogenic to medium-high temperatures (5400C) and can be significantly strengthened if required through cold working.
