Improvements in Armour Plates.
I, HENRI SCHNEIDER, of Le Creusôt (Saone and Loire) in the Republic of
France, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to armour plates of all kinds dimensions and thicknesses,
and consists in combining molybdenum with the steel used for the plates the said
per cent. of the alloy,
molybdenum varying in proportion from about 02 to about
according to the use for which the plate is required.
From the researches I have made on the influence of molybdenum on all kinds
of steel with a view to improve armour plates I have discovered that the
introduction of molybdenum in, or about, the proportions above stated and either
alone, or together with other metals or substances, such for example, as carbon,
silica, manganese, nickel, chromium, cobalt, or tungsten, either separately or
combined together communicates to the steel special properties which the other
metals, taken either separately or combined, cannot impart to it.
Steel containing molybdenum in, or about, these proportions possesses, after
tempering, a much higher limit of elasticity and is considerably tougher or
stronger, than is steel which does not contain molybdenum, all other points being
equal. The discovery of the existence of these properties in steel containing
molybdenum has led me to apply this steel for the manufacture of armour plates
with a view to obtain in such plates greater power of resistance against shock,
impact, or concussion, and penetration. The presence of molybdenum in the steel
does not detract from the usual qualities which steel possesses, such as its fitness for
forging, rolling, tempering, cementation, and the like.
Steel containing molybdenum may be obtained in a crucible or in a converter,
or on a hearth, according to the well known processes.

Improvements in Armour Plates.
1, HENRI SCHNEIDER of Le Creusôt (Saone and Loire) in the Republic of
France Manufacturer do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention relates to armour plates of all kinds dimensions and thicknesses
and consists in combining molybdenum with the steel used for the plates the said
molybdenum varying in proportion from about 0.2 to about 5 per cent. of the alloy
according to the use for which the plate is required.
From the researches I have made on the influence of molybdenum on all kinds
of steel with a view to improve armour plates I have discovered that the

either separately or combined cannot impart to it.
Steel containing molybdenum in or about these proportions possesses after
tempering a much higher limit of elasticity and is considerably tougher or stronger

Steel containing molybdenum may be obtained in a crucible or in a converter, or
on a hearth, according to the well known processes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Armour plates consisting of steel containing molybdenum in, or about, the
proportions herein before stated.
2. The manufacture of armour plates of steel containing molybdenum in, or about,
the proportions stated in combination with carbon, silica, manganese, nickel chromium,
cobalt, tungsten or the like.
