TA2 material has been widely used. Because titanium alloy has light specific gravity, high strength, corrosion resistance and other properties, it is widely used in aerospace, petrochemical industry, marine ships, machinery manufacturing and other fields. At present, It is also used in the construction of piping systems for surface ships. TA1 and TA2 are both industrial pure titanium. The difference is that the iron and oxygen content in TA2 titanium alloy is higher. Therefore, the strength of titanium alloy TA2 is higher than that of TA1, with a strength level above 440MPa. The working temperature of TA2 material is around 300℃.
