The mechanical properties of thread steel is planished steel in different environment, mechanical characteristics under various loading is shown. In fact, the important factors influencing the finishing rolling rebar prices. The mechanical properties of thread steel include tensile strength, elongation, yield point, three points. The mechanical properties of these three kinds of finishing mill the steel is as follows:
Yield point: during the tensile process, the load does not increase or start to decrease, and the specimen can continue to deform. The maximum or minimum load divided by the original cross section area is the yield point, the upper yield point and the lower yield point.
Tensile strength: when the specimen is stretched, the maximum load that is produced before breaking is divided into the original cross section area, which is called the tensile strength. It represents the maximum capacity of the threaded steel to resist breakage under the action of pulling force.
Elongation: when the sample is broken, the length of the distance and the percentage of the length of the distance are called elongation.
Besides, the surface quality of finish rolled thread steel is also an important factor to measure the price of finishing rolled thread steel. Therefore, we require that there are no defects such as cracks, scarring and folding on the surface of threaded steel.
