1020/S20C cold drawn bar or cold finished bar, carbon steel, Dia:
Plain carbon steel for mechanical engineering and automotive
It is usually supplied untreated but can be supplied to order in
the normalized or finally heat treated (quenched and tempered to
"Q" or "R" properties), which is adequate for a wide range of
It is a very popular grade of through-hardening medium carbon
steel, which is readily machinable in any condition. It is suitable
for the manufacture of parts such as general-purpose axles and
shafts, gears, bolts and studs. It can be further surface-hardened
typically to 50-55 HRC by induction processes, producing components
with enhanced wear resistance.
In its heat treated forms possesses good homogenous metallurgical
structures, giving consistent machining properties.
