All other heavy armor is shaped under the hydraulic forging pre , steam-hammer, or rolling-mill. Nickel steel is made by the addition of 34 per cent of nickel, and has proved of great value. A lower carbon and treatment at lower temperatures are secured thereby. Schneider of Le Creusot, France, was the first to succe fully use it. Carbonized armor is manufactured in the same manner as steel armor, super carbonized at a high temperature and suddenly chilled. The carbon of the surface is increased to 1 per cent by gas, bone, or other charcoal proce es; the hard face is secured in different ways by various manufacturers, generally by the application of salt ice-water.
