Product Detail

Designation by Standards

Chemical Composition (in weight %)

Description
 20NCD2 is a hardenable chromium, molybdenum, nickel low alloy steel often used for carburizing to develop a case-hardened part. This case-hardening will result in good wear characteristics.

Applications
 Gears, shafts and other applications where a hard carborized case and a tough core are desired. 

Physical properties (avarage values) at ambient temperature
 Modulus of elasticity [10³ x N/mm²]: 210
 Density [g/cm³]: 7.86

Soft Annealing
 Heat to 650-700^oC, cool slowly. This will produce a maximum Brinell hardness of 212.

Heat Treatment

Distance From Quenched End in mm

Forging
 Hot forming temperature: 1150-850^oC. 

Machinability
 Machining is done prior to carburizing to within as close a tolerance as possible. Finish machining, after heat treatment and/or carburizing, should be at a minimum so as not to impair the hardened case of the part. Machining may be done by conventional means prior to heat treatment – after carburizing machining is usually limited to grinding. 

Welding
 The alloy may be welded by conventional methods, usually gas or arc welding. Preheating at 200^oC is beneficial and subsequent heating after welding is recommended – consult the approved weld procedure for the method used.

Cold Working
 The alloy may be cold worked in the annealed condition by conventional methods. Cold working, as with machining, should be done to as close a tolerance as possible before heat treatment or carburizing.
