ASTM B348 Gr2 Gr4 TC5 Titan Bare

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'> tip și + tip titan aliaje (but mai mare decât industrial pur titan), și înalt temperatură (500-600 grad ) rezistență și creep rezistență sunt the highest among titan aliaje. titan aliaje titan are divizat în trei tipuri. The structure is stabil, 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 degree ; 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 temperature and is one of the excelent ultra-low temperature alloys.

Modelul rezistență rezistență din TA4 este ușor mai mare decât din din industrial pur titan și poate fi utilizat ca a rezistență medie material structural. În principal utilizat ca sudură sârmă în nostru țară.
