Prestressed threaded bar (or PT bars) are high-strength, high-precision, straight-line steel bars with external threads on the entire steel bar. The steel bar can be screwed onto the connector with internal threads at any section or screwed with a threaded nut with internal threads for anchoring. The utility model has the advantages of simple connection and anchorage, strong adhesion, safe and reliable tension and anchorage and the like, and is a novel material for developing prestressed concrete component. Prestressed Threaded bars are currently used to anchor and support the dam body form of the dam foundation. In the cable-stayed bridge, fully threaded bars are used as the main ribs and bridge foundations of the main tower. The use of fully threaded steel bars saves steel, reduces component area and reduces component weight. The continuous external thread is hot rolled. The shape of thread bar is shown as following figure. The main dimension ranges from 15mm-50mm and the grade ranges from 500/630Mpa to 1200/1330Mpa.

1Cr11Ni2W2MoV steel is a kind of ferrite forming element which reduces the austenite phase region, such as W, Mo, V, etc., in the low carbon 12% Cr steel, so that the steel has martensite transformation hardening ability, and the obtained one New martensitic heat resistant stainless steel. The steel has good comprehensive mechanical properties and has been widely used in the aviation industry to manufacture important parts such as engine blades, discs and shafts operating below 600 °C.
30CrMnSiA is a medium carbon with high strength and poor welding performance. 30CrMnSiA has high strength and sufficient toughness after quenching and tempering, and hardenability is also good. After quenching and tempering, the material can be used as a grinding wheel shaft, gears and sprockets. 30CrMnSiA has good processability, small processing deformation and good fatigue resistance. For shaft and piston parts and so on. Used in automobiles, aircraft, various special wear-resistant parts, etc.
50crv4 has good mechanical properties and process properties, high hardenability, adding vanadium to refine the grain of steel, reducing superheat sensitivity, improving strength and toughness, high fatigue strength, and high yield ratio, but Poor weldability and low ductility due to cold deformation. It is a higher-grade spring used as a high-load important spring with a large cross section and a valve spring, piston spring and safety valve spring with an operating temperature
