Overview of ERTi-12 (Ti-0.3Mo-0.8Ni) Titanium Alloy Welding Wire
ERTi-12 is a corrosion-resistant titanium alloy welding wire equivalent to ASTM Grade 12 (UNSR53400) and Chinese grade TA28. it provides excellent resistance to both oxidizing and reducing environments, especially in seawater and chemical media. With good weldability and moderate strength, ERTi-12 is widely used in heat exchangers, condensers, pressure vessels, and marine equipment.
