WebDelrin Homopolymer. This specific type of Delrin is 20% glass-reinforced and offers great dimensional stability, excellent stiffness and strength, good machinability, and very high creep resistance. These features make it suitable for wear-prone parts in the automotive, construction, gear manufacturing, and fixture construction industries. WebAug 29, 2003 · all parts must be low outgassing, nonmagnetic and electrically nonconductive. I thought of using aluminum for the door/rack/pinion since it is nonmagnetic. I then planned on using a class II anodize on the aluminum to make it nonconductive. However the anodizing will cause high outgassing which is not allowed.

• Austenitic stainless steels are the most common choice for high vacuum and ultra-high vacuum systems. Not all alloys are suitable; e.g. the free-machining 303 steel contains sulfur, which tends to outgas. Alloys with good weldability under argon arc welding are usually chosen. • Mild steel can be used for moderate vacuums above 1×10 torrs (1.3×10 kPa).
