Physical properties (avarage values) at ambient temperature

Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85

Soft Annealing

Heat to 650-700oC, cool slowly. This will produce a maximum Brinell hardness of 207.

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.
