Cold rolled steel 12L14 round bar is a type of steel that is manufactured using the cold rolling process, which involves passing the steel through rollers at room temperature to achieve the desired shape and finish. The '12L14' specifically refers to a type of carbon steel alloy that contains lead, enhancing its machinability. It is commonly used in various industrial applications due to its excellent mechanical properties and surface finish.
The 12L14 round bar is known for its high strength and superior machinability. It has a fine surface finish that reduces the need for further processing. Additionally, the presence of lead in the alloy provides good lubrication properties during machining, helping to prolong tool life. Its tensile strength is approximately 80,000 psi and its yield strength is around 60,000 psi, making it suitable for demanding applications.
12L14 round bars are widely used in various sectors such as automotive, aerospace, and manufacturing. They are ideal for parts that require intricate shapes and high precision, such as screws, bolts, and other fasteners. In addition, these round bars are often utilized for making components in machinery and equipment where strength and durability are critical.
The production of cold rolled steel 12L14 round bar involves several steps. Initially, raw steel is heated and then cast into ingots. These ingots are then reheated and passed through a series of rollers to shape them into round bars. The cooling process occurs after shaping, and finally, the bars are cut to the desired length and may undergo further treatments such as annealing to enhance their properties.
Some of the key benefits of using cold rolled steel 12L14 round bar include its excellent machinability, high strength, and superior surface finish. These properties contribute to reduced production costs and improved performance of the finished products. Moreover, the presence of lead within the alloy minimizes friction during machining, making it easier to work with compared to other steel types.
