No – “cold-drawn” is one specific method of producing a “cold-finished” product, but “cold-finished” encompasses several processes.
Cold-Finished (CF) Steel
An umbrella term for bar, tube or pipe that’s been finished at room temperature after initial hot working.
Common CF processes include:
Cold drawing (pulling through a die)
Cold rolling (passing between rolls)
Stretch-reducing (mechanically stretching to size)
Reaming or grinding (for tight tolerances)
Yields improved dimensional accuracy, smoother surface finish, and enhanced mechanical properties (higher yield/tensile strength, better straightness) compared to hot-finished material.
Cold-Drawn Steel
A subset of cold-finished: the workpiece is pulled (“drawn”) through a series of dies to reduce cross-section and refine surface.
Produces very precise dimensions (±0.001″–0.005″), excellent roundness/straightness, and a matte or polished finish.
Further increases strength via strain hardening and closes internal voids.
Feature | Cold-Finished (general) | Cold-Drawn (specific) |
---|---|---|
Processes | Drawing, rolling, stretching, reaming | Drawing through dies |
Tolerance range | ±0.005″–0.020″ (typical) | ±0.001″–0.005″ (very tight) |
Surface finish | Smooth to very smooth | Matte to bright, very uniform |
Mechanical properties | Improved vs. hot-finished | Further strain hardening effects |
Conclusion
All cold-drawn products are cold-finished, but not all cold-finished products are cold-drawn. “Cold-finished” simply tells you the part was sized and finished at room temperature; “cold-drawn” tells you it was specifically pulled through dies.
