NICKEL ALLOY 718 SHEET & PLATE

NICKEL ALLOY 718 SHEET & PLATE

Alloy 718 (alternatively known by Special Metals trade name Inconel 718), is a nickel chromium alloy which can be heat treated to give high strength, good corrosion resistance and is readily fabricated into complex parts with a very good resistance to post-weld cracking. Alloy 718 can work effectively between -423 to 1300 deg F.
