Alloy 20 Threaded Bars
The threaded rod is built on a circular bar of the proper grade and diameter. For the mass production of threaded bars with a uniform diameter and grade, a thread rolling machine is commonly utilized. The circular bar is run through two hardened steel rollers in this process to imprint the thread onto it. The round bar is changed into an Alloy 20 Threaded Bars by the extraordinarily high pressure of these rollers, which are perfectly spaced apart and rotate in the opposite direction to the direction the round bar is being passed through.
In this largely automated procedure, the round bar is forced past the rollers to imprint the thread onto the surface. The threaded bar's edges are polished after being sawed to size to produce a finished, rounded, smooth surface.
A non-standard threaded rod is often produced by a cutting procedure. After being cut to a length that is somewhat longer than intended, the circular bar is put through a machine that eliminates the surface thread as it is forced along. Next, the threaded bar is lengthened and polished. Because it requires more time to complete than thread rolling, this method is more expensive.
The Alloy 20 Threaded Bars are often made of carbon steel, mild steel that has been zinc-plated, or stainless steel, depending on the intended usage.
Applications of Alloy 20 Threaded Bars
Although an Alloy 20 Threaded Bar can be used anywhere a large screw, bolt, or anchor bolt is needed, its main purpose is when a bolt or screw's length or diameter is insufficient. This function is typically served by it in large construction projects like bridges. Since the required length and diameter vastly outweigh those of a normal bolt, a threaded rod is used in this situation.
High tension and vibrating loads, such as those found inside any combustion engine block, are another application.
