(4) -1/4″ Round Steel Plates, 4″ diameter, Cold Rolled Steel, Disk, Circle

This set of four (4) 1/4″ steel plates is made of cold rolled steel. If you are after the toughest material and cleanest fabrication for your build, these 4″ precision laser cut plates are the best you will find. Compared to hot rolled steel, cold rolled steel offers a variety of advantages, such as:Greater strength: Cold rolled steel can exhibit strength up to 20% greater than that of hot rolled steel, which makes it more suitable for use in high-stress applications.Better surface finishes: Parts and products made from cold rolled steel generally have a smooth and shiny surface that is free of rust and scale.Higher precision: Unlike hot rolled steel, cold rolled steel does not shrink after the forming process. This quality allows for the creation of highly precise components that require little to no secondary processing.
