Inconel 617(UNS  N06617 W.Nr.2.4663)

1.Inconel 617 INTRODUCTION

A nickel-chromium-cobalt-molybdenum alloy  with an exceptional combination of metallurgical  stability, strength and oxidation resistance at  high temperatures. Resistance to oxidation  is enhanced by an aluminum addition. The  alloy also resists a wide range of corrosive  aqueous environments. Used in gas turbines  for combustion cans, ducting and transition  liners; petrochemical processing; heat-treating  equipment; and in nitric acid production.
