Generally, Inconel 600 forgings shall be manufactured in conformance with ASTM B564 UNS N06600. In order to investigate the chemical composition and mechanical properties under different conditions, test specimens sized of Φ20 mm x 200 mm(L) are prepared from the original 300 mm x 200 mm Inconel 600 forgings. The solution treatment is conducted on each test piece at different temperatures from 850°C to 1050°C, cooled by air or cold water respectively.
