Cold Drawn Square Bar

Cold drawn steel is ideal for long products, like shafting and structural parts, as well as consumer products that require an aesthetic finish. The pressure required to make cold drawn steel increases tensile and yield strength and results in a smooth, polished finish. Cold drawn steel does not change shape during processing, so the finished product has dimensional consistency and improved straightness. Not only does this process enhance the physical properties of the steel bar, it also improves the dimensional tolerances, straightness, and surface appearance.

Square Bar Applications

Square steel bars are known for their hardness, strength, and exceptional wear resistance. These multipurpose steel bars are mainly used for manufacturing and repair. Their sharp corners and excellent mechanical properties make them ideal for multiple applications, including structural, fabrication, manufacturing, and even repairs. Square steel bars are easy to cut and weld, ideal for cold bending and forming applications, and have good machinability and case hardening properties.

Because of its enhanced mechanical properties, tight dimensional tolerances, improved strength and superior finish, cold drawn square bars are used across numerous industries, including:

Common applications of cold drawn square bars include:

  • Shafts
  • Axles
  • Dowels
  • Slides
  • Threaded Fixtures
  • Tooling Blocks
  • Power tools
  • Pins
  • Anchor bolts
  • Structural parts
  • Ratchets
  • Tool holders
  • Screw machines
  • CNC lathes
  • CNC mills
  • Rotary transfer machining
  • Hydraulic fittings
  • Gears
  • Bushings
  • Fasteners
  • Cylinders

WHAT ARE THE BENEFITS OF COLD DRAWN SQUARE STEEL BARS?

The cold-drawn process involves hot rolled bars or hot rolled steel coils being brought down to room temperature. Once the steel reaches room temperature, it is then hammered and rolled to ensure it fits through a die. It is then pulled through the die to reshape it into a thinner shape without altering the volume. Because cold drawn steel does not change shape during processing, the finished product has a predictable thickness and shape. Multiple passes through the die are often required before the steel takes on the desired shape and thickness.

This process allows cold drawn steel to have an increased yield and tensile strength compared to other types of steel. The following are some characteristic and benefits of cold drawn steel:

Increases cost effectiveness

optimizing machinability and reduces yield loss

 

Compared to hot rolled steel, cold drawn steel products can be manufactured to give more precise dimensions, tighter tolerances, and sharper corners. This is because hot rolled steel products changes in shape during the cooling process. Cold drawn steel also has an improved yield and tensile strength and a better surface finish over hot rolled steel products. Finally, cold drawn square steel bars have sharper corners than the more rounded corners of hot rolled square steel bars.

Cold drawn square steel bars may be harder to work with than their hot rolled equivalents; however, they make up for it with more accurate sizes, smooth surfaces, enhanced mechanical properties, and increased machinability. Also, because drawn steel usually needs multiple passes through the die to achieve the right dimension and shape, the production costs are higher than hot rolled steel.
