Bar condition
Most bar greater than about 1” diameter is hot-rolled and often followed by other processing
- Annealing
- Hardening (quenching) and tempering (martensitic alloys)
- Aging (PH alloys)
- Cold finishing. Mechanical surface preparation (turning, grinding, polishing, …) to improve dimensional tolerance and enhance appearance. It is not the same as cold-drawing and does not affect mechanical properties.
Most common for > 1”
- Hot rolled
- Hot rolled + cold-finished
Bar ≤ 1” diameter is cold-drawn and often followed by other processing
- Annealing
- Hardening (quenching) and tempering (martensitic alloys)
- Aging (PH alloys)
- Cold finishing. Mechanical surface preparation (turning, grinding, polishing, …) to improve dimensional tolerance and enhance appearance. It is not the same as cold-drawing and does not affect mechanical properties.
Most common for bar ≤ 1” diameter
- Cold-drawn + anneal
- Cold-drawn + anneal + cold-finished
Wire is available in one of these conditions
- Cold-drawn
- Cold drawn + annealed
