I am designing temperature varying tube for VSM, especially high temperature. I don't have any experience on materials for this component. Please give me your idea about choosing material. Requirements for the tube is :shy:: - easy for machining - to use for medium vacuum (10^-4 Torr). - nonmagnetic material - to use in temperature range of 100 - 1100 K - diameter of 20 - 35 mm; thickness of ~ 1 mm Thanking you!
