Product Description

APPLICATION:

Alloyed case hardening steel for the parts which require high core tensile strength and high hardness. Susceptible to average seized parts with high wearing resistance and variable loading such as: gears, screws, bolts, bushing, camshafts.

TECHNOLOGICAL INFORMATION:

Steel adjusted for cutting with a cutting machine. The carburising temperature range can be higher than provided in the file (depending on the carburising process)

SEMI-FINISHED PRODUCTS:

Steel adjusted for cutting with a cutting machine. The carburising temperature range can be higher than provided in the file (depending on the carburising process)

TECHNOLOGICAL TREATMENT PROCESSES:

Technological treatment processes Possible application Temperature, °C
Hot forming Forging + 1150 - 850
Rolling + 1150 - 850
Thermochemical treatment Carburising + 880 - 980
Carbonitriding + 860 - 950
Heat treatment Annealing Normalising + 870 - 910
Soft annealing + 650 - 700
Heat treatment after carburising 1 ) Core hardening + 860 - 900
Intermediate annealing + 670 - 720
Case hardening + 780 - 820
Tempering + 150 - 200
1)   If possible, hardening has to be performed with the temperature equal or close to the heat treatment temperature
