ASTM B338 and ASME SB338 cover 28 grades of titanium and titanium alloy tubes for surface condensers, evaporators, and heat exchangers together with grades Gr2.

ASTM B338 GR2 TITANIUM TUBE MECHANICAL PROPERTIES

ASTM B338 GR2 TITANIUM TUBE HIGHLIGHTS

Titanium Grade 2 has good ductility, which allows for cold formability. To prevent cold forming concerns, the minimum bend radius for material under 0.070" thick should be 2T, while 2.5T should be used for material over 0.070". This kind of ASTM B338 material can also be easily machined, hot worked, and welded.

We provide gr2 titanium tube, sb 338 gr2, steel fitting, steel hose fittings, etc. For more information, please feel free to contact us!
