Grade 2 titanium alloy, UNS number R50400, has excellent corrosion resistance and good mechanical properties, suitable for various industrial applications that require strength and corrosion resistance. Due to its good ductility and weldability, it is widely used in aerospace, chemical, marine and medical equipment.
The impurity content of industrial pure titanium is higher than that of chemical pure titanium, so its strength and hardness are slightly higher. Its mechanical and chemical properties are similar to those of stainless steel. Compared with titanium alloy, pure titanium has lower strength and better plasticity. It can be welded, cut and has good corrosion resistance. It is better than austenitic stainless steel in oxidation resistance, but has poor heat resistance. The impurity content of
Grade 1, Grade 2 and Grade 3 increases successively, and the mechanical strength and hardness increase successively , but the plasticity and toughness decrease successively .
It is mainly used for stamping parts and corrosion-resistant structural parts with working temperature below 350℃, which are not subjected to small forces but require high plasticity, such as aircraft frames, skin ship valves, pipelines, seawater desalination equipment, etc., pumps, cooler agitators, distillation towers, impellers, compressor valves, diesel engine pistons, etc. in chemical industry. Grade 1 and Grade 2 can be used as low-temperature structural materials below -253℃ due to their good low-temperature toughness and low-temperature strength.
