ASTM 5120 / EN 20MnCr5 1.7147 Alloy Steel Bar / Rod Forged
GENERAL CHARACTERISTICS OF ALLOY STEEL 5120
This is a low-carbon chromium-bearing, case-hardening alloy steel
used where good wear resistance and toughness are required.
This alloy is used for highly stressed parts with medium cross
sections for automotive and general engineering applications, such
as forged camshafts and gears, gear shafts, bushings and connecting

This alloy would be forged between 2200 and 1700ºF (1200 and
Annealing: This alloy is seldom annealed. Structures of better machinability
are developed by normalizing or by isothermal transformation after
Normalizing: 1650-1700ºF (900-930ºC.)
Carburizing: 1650-1740ºF (900-950ºC) and oil quench.
Hardening: Core: 1560-1620ºF (850-880ºC) and oil quench. Case: 1490-1540ºF
(810-840ºC) and oil quench
Tempering: 340-410ºF (170-210ºC.)
Machinability: The alloy is best machined in the normalized condition prior to
Weldability: The alloy is easily welded, but should be welded prior to case
