Steelmet Industries offers SAE1018 Cold Drawn Square Bars with clean surface finish, tight dimensional tolerances, and superior machinability. These bright bars are ideal for manufacturing components that demand moderate strength with excellent weldability and formability. SAE1018, a medium-low carbon steel grade, is widely chosen in industries like:
Automotive (shafts, pins, spacers)
Machinery & Equipment (machine parts, jigs, tools)
Fabrication & Construction (frames, supports, and brackets)
General Engineering
The cold drawing process enhances strength and surface quality while maintaining good ductility and consistency across batches.

❓ Frequently Asked Questions
Q1. Is SAE1018 suitable for welding and bending?
Yes. SAE1018 is highly weldable and can be bent or formed without cracking due to its balanced carbon content.
Q2. How is cold drawn steel better than hot rolled steel?
Cold drawn steel has tighter dimensional tolerances, a cleaner surface, improved strength, and is better suited for machining.
Q3. Is any heat treatment required for SAE1018 cold drawn squares?
Generally, no. It can be used as-is. However, annealing or stress relieving can be performed based on the application.
