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 Bar 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.

TMT Bars (Thermo Mechanically Treated) Steel, can be described as new-generation-high-strength steel having superior properties such as Weldability, Strength, Ductility, and Tensility, Which meet the highest international quality standards. One of the most common types of TMT Construction is used for home and building construction. The production of quality TMT Bar depends on three major factors - quality raw materials, a properly designed and automated mill, and a well-designed quenching and temping technology. All bars must be purchased based on the properties of yield strength, tensile strength, and elongation values. The range we provide starts from a 6mm round bar in the required length.

1. Use solid 45# carbon or 40Cr steel as raw material. 2. Tensile Strenth is more than 540MPa, 630MPa and 720MPa. The standard rebar threaded coupler is suitable for connecting two bars of the same diameter, where one bar can be rotated. It comprises an internally threaded sleeve with two right hand threads which are tapered towards the middle of the coupler. The bar ends are square cut and thread is onto the bar. A nominal allowance of +25mm should be allowed per threaded bar end for square cutting the bar end. The couplers are generally torqued onto the reinforcing bar in the bar threading shop, the internal threads protected by plastic end caps. The threaded ends of the continuation bar are protected by plastic thread protectors.
The hardenability, hardening and tempering hardness, wear resistance and strength of Cr12MoV die steel are higher than Cr12. Used in the manufacture of various cold-punching dies and tools with large cross-sections, complex shapes and heavy working conditions, such as punching die, trimming die, piping die, steel plate Cr12Mov thick plate deep drawing die, circular saw, standard tool And gauges, thread rolling molds, etc.
Used as important tempering parts requiring good toughness, high strength, and large size, such as heavy machinery high-load shafts, turbine shafts larger than 250mm, helicopter rotor shafts, turbojet turbine shafts, blades, high Load transmission parts, crankshaft fasteners. Gears, etc.; can also be used to operate rotor shafts and blades with temperatures exceeding 400 °C; it can also be used to make important parts of special performance requirements after nitriding treatment. It can be used after low temperature tempering or after isothermal quenching. Use for strength steel.
