ANSI/ASME B18.22.1 TABLE1A Titanium Plain Washers-Product GradeA are usually thin pieces of various shapes used to reduce friction,prevent leakage,isolate,prevent looseness,or disperse pressure.
Titanium materials and Titanium alloy structures have this part,subject to Titanium threaded fasteners,Titanium bolts and other metal fasteners bearing surface is not large,so in order to reduce the pressure surface of the pressure protection is connected to the surface,the use of Ti Washers.
