Titanium and titanium alloy classification Industrial pure titanium: TA1, TA2, TA10

The biggest feature of titanium is its low quality (density 4.51g/cm3), high strength, excellent corrosion resistance, and good low temperature performance. It has excellent corrosion resistance in seawater and most acid, alkali, and salt media. In production, its corrosion resistance is 10 times higher than that of ultra-low carbon austenitic stainless steel.

Welding characteristics of titanium products Titanium equipment welding is very easy to oxidize, nitridize and embrittlement. A large amount of hydrogen begins to be absorbed at 400°C. Hydrogen is one of the most harmful elements of titanium, which reduces the plasticity and toughness of titanium, leading to embrittlement. When cooling, hydrogen does not have time to escape and produces pores. Therefore, the welding properties of titanium and other metals should be considered for titanium pressure vessels.

High-pressure reactors are commonly used composite plates of titanium and carbon steel, with titanium as the corrosion-resistant layer and carbon steel as the base layer.
