14NiCrMo13-4 Alloy Steel DIN 1.6657
Description

14NiCrMo13-4 Alloy Steel as also named in US standards is a case hardening steel used in forgings to eg rock drilling tools. It can be used to make gear parts exposed to the highest stresses and wear conditions. Typical components include gears, planet wheels, drive pinions, shafts, bushes, and sleeves. Results in high core strength and excellent toughness in the components and are very suitable for parts with a large diameter.

Heat Treatment

Soft Annealing: Heat EN36C to 825oC, cool slowly. This will produce a maximum Brinell hardness of 217.
Hardening: Harden from a temperature of 825-850oC, followed by oil or quenching.
Tempering:– After carburizing and hardening, the steel is tempered between 140°C and 200°C as required.
For use in the non carburized heat treated condition, temper in accordance with properties required.

Application:

Alloyed case hardening steel for parts with a required core tensile strength of 1000 – 1300 N/mm² and good wearing resistance as boxes, piston bolts, spindles, camshafts, gears, shafts and other mechanical controlling parts.Especially in wheels and stopcock.
