ASTM B348 Gr2 Gr4 TC5 Titanium Bars

TA4 titanium alloy is an α-type titanium alloy. It is in an α-type single-phase state at room temperature and service temperature. It cannot be heat treated (annealing is the only form of heat treatment) and mainly relies on solid solution strengthening. Room temperature strength is generally lower than β'> type and α+β type titanium alloys (but higher than industrial pure titanium), and high temperature (500-600°C) strength and creep strength are the highest among titanium alloys. Titanium alloys are divided into three types. The structure is stable, the oxidation resistance and welding performance are good, the corrosion resistance and cutting processability are also good, but the plasticity is low (the thermoplasticity is still good), and the room temperature stamping performance is poor. The most widely used one is TA7, which has medium strength and sufficient plasticity in the annealed state, has good weldability, and can be used below 500°C; when the content of impurity elements (oxygen, hydrogen, nitrogen, etc.) in the gap is extremely low, It also has good toughness and comprehensive mechanical properties at ultra-low temperatures and is one of the excellent ultra-low temperature alloys.

The tensile strength of TA4 is slightly higher than that of industrial pure titanium and can be used as a medium-strength structural material. Mainly used as welding wire in our country.
