The material spec is Inco 718 Material - AMS-5662 Heat Treated to AMS-5663 and we cannot find anyone that heat treats it longer than 3 foot here in Michigan. Boston Centerless can get it but I don't know their supplier and we hwant to havemore than 1 option for material. And I feel we can get it cheaper if we buy the stock and have a local grind house grind it. Any help is greatly appreciated.
