S45c Cold Drawn Steel Square Bar
S45C is a carbon steel grade that is commonly used in machinery parts and structural applications. Cold drawn steel square bars are produced by cold-drawing hot rolled steel bars through dies to achieve the desired shape and size. This process results in a steel bar with improved dimensional accuracy, surface finish, and tensile strength. S45C cold drawn steel square bars are used in various applications such as shafts, gears, studs, bolts, and machine parts. They are also used in construction, automotive, and aerospace industries due to their high strength and durability.
