COLD DRAWN STEEL bar
Cold drawn steel can be found in many consumer products that we use on a daily basis, as it has the physical and appealing characteristics that make it useful for many products. We’ve answered some common questions asked when it comes to cold drawn steel, also known as cold finished steel.
What is Cold Drawn Steel?
Steel that is drawn passes through a series of dies to achieve a desired shape is known as drawn steel. Dies apply specified amount of pressures with the help of a machine press, and the steel starting stock typically has to be passed through the die or a series of dies more than once. Cold refers to the drawn steel being manufactured at room temperature, which requires additional pressure to shape the steel, but gives the steel extra qualities and visually aesthetic appearance.
What’s the Cold Drawn Steel Process?
Initially, a steel manufacturer starts with a starting stock of steel product – either hot rolled straight bars or hot rolled steel coils - that is brought down to room temperature. Regardless if the end product is bar, tube or wire, the undrawn steel product is drawn through a die, which stretches the starting stock into the desired shape and size. This is done with the help of a grip that attaches to the steel stock and pulls the steel through the die. To the naked eye, the steel does not change much in shape through a single pass through the die, and usually takes multiple passes before it takes on the desired end shape.
These are the benefits of Cold Drawn Steel Wire
· More accurate dimensional size tolerances.
· Increased Mechanical Properties, higher yield strengths, tensile strength and hardness.
· Improved Surface Finish, reduces surface machining and improves quality.
· Allows for higher machining feed rates.
· Superior Formability, responds better to spheroidization
· Maximizes machinability, thereby reducing yield loss.
