Krupp process (?). (Iron Metal.)
A process practiced by Friedrich
Krupp, Essen, Germany, for washing pig iron, differing from
the Bell process in using manganese as well as iron oxide, and
performed in a Pernot furnace. Called also the Bell-Krupp
A process for the
manufacture of steel armor plates, invented or practiced by
Krupp, the details of which are secret. It is understood to
involve the addition of chromium as well as nickel to the metal, and
to include a treatment like that of the Harvey process with unknown
variations or additions. The product is mentioned by some authors, as
Improved Harvey, or Harvey-Krupp armor plate.
