2. DESCRIPTION:
AISI 4142/4145/4147 steel bar is a medium carbon, chromium and molybdenum alloy steel. The
normal condition is hardened
and tempered to a range of 850 to 1000 Mpa ultimate tensile
strength for bar sizes up to 220mm
diameter. Limited ruling sections may apply according to Australian
Standards
3. APPLICATIONS:
AISI 4142/4145/4147 steel bar is an ideal general purpose high tensile constructional steel
ready for use after machining. It is
used for shafts, axles, studs & bolts, large gears and light
duty form rolls. The steel is suitable for
induction or flame hardening.
