Abstract:
Due to its advantages of high specific strength, corrosion resistance, high production efficiency and good heat exchange effect, the TA2 cold rolled titanium strip is widely used in the industries such as electric power, chemical industry, seawater desalination and other fields. In this paper, TA2 cold rolled titanium strip for welded pipe is prepared from EB ingot slab by using short process and low-cost electron beam cold bed melting furnace, and its chemical composition, mechanical properties and gold content are analyzed. The results show that the low strength and high elongation and surface hardness in the horizontal direction can effectively avoid the defects like the scratching in the process of bending forming of the welded pipe, which can meet the usage requirement of the thin welded pipe.
