Model Number: CMA74
Brand Name: 19NiCrMo4
Key Specifications/Special Features:
DescriptionSpecial structural steel.ApplicationsSpecial purpose production. Parts of larger cross-sections where higher toughness is demanded, for gears, crankshafts and morePhysical properties (average values) at ambient temperatureModulus of elasticity [103x N/mm2]: 210
Density [g/cm3]: 7.80
Soft Annealing
Heat to 620-660oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 255.
Intermediate Annealing
Temperature: 600-630oC.
Carburizing
Temperature: 860-890oC.
Hardening
Harden from a temperature of 780-810oC followed by oil quenching or thermal bath at 180-220oC.
Tempering
Tempering temperature: 150-180oC.
Forging
Hot forming temperature: 1050-850oC.
