ERTi-12 GMAW-GTAW Solid wires




ERTi-12

 
TYPE 
Solid drawn Titanium Grade 12 welding wire .
APPLICATIONS 
This alloy finds his applications in chemical industry and offers excellent Weldabillity. Often recomended for pressure vessels and piping for its superior strenght alone.
PROPERTIES 

ER Ti-12. Grade 12 (Ti 0.8Ni0.3Mo) is an intermediate strength grade originally developed to provide enhanced crevice-corrosion resistance in high temperature brines, but at lower cost than Grade 7. The improved performance is believed to be the result of Ni++ and Mo++ ions that alter the surface electrochemistry of the material in the crevice or under a surface deposit. Grade 12 has better elevated temperature properties than Grade 2 or 3 and is sometimes specified for pressure vessels or piping for its superior strength alone.
