  • ASTM A108 Certified
  • 63,800 PSI Tensile Strength
  • Excellent Machinability
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

1018 cold rolled steel is a low-carbon alloy that has been cold drawn through dies, a process that increases its strength, hardness, and dimensional precision compared to hot rolled steel. This material offers a good balance of toughness, ductility, and strength, and is easily welded. Its uniform, smooth surface is ideal for parts that require a high-quality finish or subsequent plating, and it is well-suited for case hardening treatments.

As a medium-sized profile, the 5/8" square bar is highly versatile for manufacturing applications. It is frequently used to produce medium-duty components like shafts, axles, machine keys, mounting blocks for jigs, and other precision-machined parts where strength and a superior surface finish are critical design factors.
