***5 Cold Drawn Carbon Steel Round Bar is used where greater strength is required than can be obtained from the lower carbon steels. It responds to heat treatment, and a wide range of properties can be obtained. Applications include shafts, machinery parts, bolts, pinions, gears, etc.

Step1: Our process begins with either hot-rolled steel coils or
hot-rolled straight bars from the mill. When hot-rolled bars are
used, they are drawn individually. When coils are used, overhead
cranes use C-hooks to safely lift the coil onto the
“Payoff-Decoiler.”
Step2: Steel unwraps from the “Payoff De-Coiler” and is fed through
the horizontal and vertical pre-straightener rollers to “break the
memory” of the coil.
Step3: Steel continues on through the shot blaster so that the
surface of the bar can be cleaned of all scale and rust.
Step4: Now the steel is push-pointed through a die. The drawing
unit will then pull the steel through that same die, in a
continuous motion.
Step5: Continuous straightening is maintained by passing the steel
through more rollers.
Step6: Non-destructive testing is in place on all drive lines to
ensure that surface defects from the raw materials are being
detected and sorted out.
Step7: More straightening processes are in place throughout the
draw line.
Step8: Shear barrels or shear knives will shear or cut the bar to
the customer’s desired length.
Step9: The final straightening process occurs at the *-roll
straightener when the bar passes through the large concave and
convex rolls. Guide blades, angles and pressure all contribute to
the final straightness of the bar.
Machinability rating is approximately *4% based on ***2 as **0%. Average surface cutting speed is between *5 and **5 feet per minute.
WeldabilityDue to higher carbon content, this material is not readily
welded.With thin sections and flexible design, gas or arc welding
may be used without preheating, but in joints over 1/2” to 3/4”
thick preheating is necessary. To develop equivalent strength in a
weld, a low alloy filler is recommended. Stress relieving
after welding is also recommended. The grade of welding rod to be
used depends thickness of section, design, service requirement,
etc.
This steel is essentially water-hardening, but it may be
quenched in oil. The recommended quenching temperatures are ***0ºF
for water and ***5ºF for oil. A wide range of mechanical properties
can be obtained by tempering at different temperatures between
**0ºF and ***0ºF. Tempering in the range from **0ºF to **0ºF should
be avoided.
Packaging
Lengths of *8″ and under are bundled and strapped to skids, or put in corrugated shipping containers. Longer lengths are shipped in 1,**0lb bundles, 5 bands per bundle.
