UNS R50250 Round Welded Titanium Tubing Grade 1
UNS R50250 Titanium Pipe ASME SB338 , Titanium Grade 1 SS Seamless Pipes
Description:
Commercially Pure Titanium Grade 1 is one of the softest and most ductile grades exhibiting the greatest formability. It has excellent corrosion resistance property, excellent weldability and is used in a wide variety of applications. This grade material is mainly used in marine and chemical industries where the parts are subjected to very harsh environments. This material is also used for fabricating anodes for cathodic protection applications.
