- 1018 Steel Construction
- ASTM A108 Certified
- 63,800 PSI Tensile Strength
- Excellent Machinability (70%)
1018 is a low-carbon steel produced through a cold drawing process, resulting in increased strength, a smooth surface, and superior dimensional accuracy compared to hot rolled steel. It conforms to ASTM A108 and provides a balance of toughness, strength, and ductility. Its excellent machinability and good weldability make it a highly versatile material for general-purpose fabrication and machining.
The small 5/16 inch diameter is perfectly suited for producing high-tolerance parts such as dowel pins, small motor shafts, precision axles, and fastener blanks. It is a common choice for custom hardware, jigs, and fixtures where accuracy and a clean finish are essential.
