Affinity Of Nickel Steel For Carbon





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.
