Affinity Of Nickel Steel For Carbon






Category: HEAT TREATMENT OF STEEL

The carbon- and nickel-steel
gears are carburized separately owing to the difference in time
necessary for their carburization. Practically all printed information
on the subject is to the effect that nickel steel takes longer to
carburize than plain carbon steel. This is directly opposed to
the conditions found at this plant. For the same depth of case,
other conditions being equal, a nickel-steel gear would require
from 20 to 30 min. less than a low carbon-steel gear.

From the quenching machines, the gears go to the sand-blasting
machines, situated in the wing of the heat-treating building, where
they are cleaned. From here they are taken to the testing department.
The tests are simple and at the same time most thorough.
