Grade 1 titanium alloy, UNS number R50250, as the most basic type of titanium alloy, has excellent corrosion resistance and good formability. It has high purity, excellent ductility and low strength, and is suitable for industrial applications with high requirements for lightweight and corrosion resistance. Due to its excellent oxidation resistance, Grade1 titanium alloy is often used in aerospace, marine engineering, chemical equipment, medical equipment and other fields.
The impurity content of industrial pure titanium is higher than that of chemical pure titanium, so its strength and hardness are also 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 Grade1 , Grade2 and Grade3 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 much force but require high plasticity, such as aircraft frames, skin ship valves, pipelines, seawater desalination equipment, pumps, cooler agitators, distillation towers, impellers, compressor valves, diesel engine pistons, etc. in chemical industry. Grade1 and Grade2 can be used as low-temperature structural materials below -253℃ due to their good low-temperature toughness and low-temperature strength.
