Product Description
ALLOY STEEL 5120 (GB 20Cr).
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.
APPLICATIONS
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 rods.
FORGING
This alloy would be forged between 2200 and 1700ºF (1200 and 925ºC.)
HEAT TREATMENT
Annealing: This alloy is seldom annealed. Structures of better machinability are developed by normalizing or by isothermal transformation after forging.
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 case hardening.
Weldability: The alloy is easily welded, but should be welded prior to case hardening.
