Cold finished ASTM A108 is a type of carbon steel that undergoes a cold drawing process to achieve its final dimensions and surface finish. The cold drawing process results in improved strength, surface quality, and dimensional accuracy compared to hot rolled steel. Cold finished ASTM A108 has high tensile strength and good machinability, making it a versatile material for various applications.

Cold finished ASTM A108 is commonly used in the manufacturing of parts that require high strength, such as shafts, bolts, studs, and gears. It is also used in the construction of machinery and equipment, as well as in the automotive and aerospace industries. The improved dimensional accuracy and surface finish of cold finished ASTM A108 make it a preferred choice for precision parts that require tight tolerances.

Fastmetals.com offers cold finished ASTM A108 in round bar. The rounds are available in diameters ranging from 3/16 inches to 1 3/4 inches. Each product page provides additional information on the specific dimensions and tolerances of the material.
