Nickel Alloy 718 Bar

Alloy 718

Description

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 postweld cracking. Alloy 718 can work effectively between -423 to 1300 deg F.
