    This formula is modified for Harveyed or Krupp-cemented armor if capped projectiles are used, the d is then multiplied by a further factor of four. Krupp’s formula (1895) is given for use when face-hardened armor is confronted with uncapped armor-piercing projectiles: t = 10-3.1766 * w 0.5 * v 1 * d -0.5.

    Krupp also adopted the cementation process for armor, but instead of using solid hydrocarbon as in the Harvey process, used a gaseous hydrocarbon, illuminating gas being passed while hot across the face of the heated plate. This gaseous cementation has been frequently used, but has been gradually superseded by the use of solid hydrocarbon.
