ALLOY DESCRIPTION

HAYNES ® 617 alloy is a nickel-chromium-cobalt-molybdenum alloy with a good combination of metallurgical stability, strength, and oxidation resistance at high temperatures. The alloy is readily formed and welded by conventional techniques. HAYNES 617 alloy is used in applications such as gas turbines for combustion cans, ducting, and transition lines. For modern applications, HAYNES 230 ® alloy should be considered as a replacement (ask for brochure H-3000).
