| AISI C-1045 TURNED, GROUND & POLISHED
ROUND |
1045 is a medium carbon steel which responds
to heat treating, forging, and induction hardening. This grade is
used when a greater strength and hardness is required than can be
obtained from lower carbon steel. 1045 is the most popular shafting
grade in the medium carbon range. It is also an excellent grade
for chrome plating. Note the diameter tolerances at the bottom of
the page (approx. twice as close when compared to 1018 cold finished).
Applications include gears, shafts, bolts, studs, machine parts,
axles, forming dies, and tool shanks.

| AISI C-1141 TURNED, GROUND & POLISHED
ROUND |
1141 is a medium carbon steel with the
addition of sulphur for improved machinability. It responds favorably
to heat treating when greater strength and toughness is required.
1141 is not recommended for welding due to its higher carbon and
sulphur content. Note the diameter tolerances at the bottom of the
page (approx. twice as close when compared to 1018 cold finished).
Applications include gears, shafts, bolts, studs, axles, and tie
rods.

| 12L14 FREE MACHINING BARS |
12L14 is basically a resulphurized and
rephosphorized screw machine stock to which lead has been added.
These elements combine to produce an extraordinarily fast machining
steel (machinability rating is 193%, based on grade 1212 as 100%.
Average surface cutting speed is 325 feet per minute). 12L14 offers
good ductility combined with finer surface quality. Due to high
sulphur content, 12L14 is not considered as weldable as other low
carbon steels. Applications include bushings, couplings, inserts,
and hydraulic hose fittings.
