ASTM B348 gr2 gr5 forged titanium square bar/ titanium bar/rectangular titanium rod
As an important material for aerospace, TC11 is an α+β dual-phase titanium alloy with the phasetransfer temperature between 998 and 1020°C. Due to its excellent properties (such as high strength and fatigue resistance), it has become an ideal material to produce aircraft engine parts.
TC11 titanium alloy under 300°C/5000 h has good microstructure and performance stability, different temperature transient high-temperature properties, such as tensile, creep and lasting, and double annealing and isothermal annealing. Through the normal annealing treatment of semi-finished products of TC11 titanium alloy, it can meet the requirements of aircraft structure temperature (below 300°C).
