Description
EUGENE-SCHNEIDER, or LE CREUSOT, F'aANcE;
ALLOY FOR ABMOR-PLATES AND OTHER USES.
Specification of Letters Patent.
Patented June 22, 1909.
Application filed August 2, 1907. Serial No. 386,834.
To all whom it may concern:
Be it known that I, EUGENE SCHNEIDER, citizen of the Republic of France, residing at Le Creusot, Sane-et-Loire, France, have invented certain new and useful Improve ments in Alloys for Armor-Plates and other Uses, of which the following is a specification.
The cementation of armor plates has resulted in considerably increasing the resist ance offered to projectiles relatively to that obtaining with the homogeneous armor plates previously employed; so that recourse is now always had to cemented armor plates hardened by diiferent processes, for the purpose of opposing the passage of projectiles at high velocities and effecting their fracture by shock upon the impact face of such plates. Although presenting great resistance to uncapped projectiles, cemented armor plates offer but a relatively small resistance and one which is far from uniform when they are attacked by capped projectiles; in this case they present little superiority over uncemented plates of equal thickness.
The present invention relates to alloys by means of which it is possible to form homogeneous armor plates giving results superior to those obtained with cemented plates. The homogeneous armor plates manufactured with these alloys present a more uniform resistance to the attack of uncapped projectiles and they also offer greater resistance to capped projectiles than, the best armor plates heretofore known.
The improved alloys are constituted in the following manner :A steel comprising, in addition to the iron, per hundred parts:
Carbon -030 to 0.50 Manganese less than 0.350 -Nickel .8 to 5 Ohromi'umu-fl' .0.5 to 1.5
and while the metal is in fusion from 0.5 to 1.5% of molybdenum or 1 to 3% of tungsten, or again, 0.2 to 0.5% of vanadium are added thereto.
Instead of adding one only of the metals indicated above to the steel separately, two may be added simultaneously; for example molybdenum and tungsten together, or molybdenum and vanadium, or tungsten and vanadium. The three metals, tungsten, molybdenum and vanadium, may also be added simultaneously. In these latter cases the proportions of the metals added to the steel are reduced in a proportionate manner as regards each of them.
The composition of the steel, indicated above, is that which gives the best results in practice, but it is nevertheless capable of slight modifications.
The alloys constituted in the manner herein described present special properties due to their homogeneity and to the. presence in the initial steel of the molybdenum, tungsten or vanadium separately or combined in twos, or all three added together.
Without any cementation or addition of special bodies to one face, While at the same time obtaining the proper qualities for resisting the attacks of capped and uncapped projectiles Without cracking or scal ng, in a more satisfactory manner than the armor plates hitherto known; this improvement is particularly noticeable in the case of the capped projectiles which are employed in all navies.
Apart from the manufacture of armor plates, the hereindescribed alloys are capable of numerous uses precisely owing to their homogeneity and their great resistance.
What I claim is 1. A steel alloy for armor plates containing carbon,0.3 to 0.5 per cent., manganese not over 0.35 per cent., nickel 3 to 5 per cent., chromium 0.5 to 1.5 er cent., molybdenum 0.5 to 1.5 per cent., and the remainder of iron.
2. A steel alloy for armor plates containing in one hundred parts, in addition to iron,
carbon 0.3 to 0.5, manganese less than 0.35,
nickel 3 to 5 ,Ch1"01ni u m 0.5 to 1.5, molybde- .In testimony whereof I have afllxeu my num less than 1.5 and tungsten less-than 3.v signature in presence of two Witnesses. -3. A steel alloy for armor plates conta-inf ing carbon 0.3-t0 0.5 per cent manganese EUGENE SCHNEIDER 5 less than 035 per cent., nickel 3 to 5'per cent, Witnesses:
chromium-10.5 to 1.5- per cent, tungsten less H. (100x12,
than 3 per cent., and the remainder of iron. 7 CHARLES DE LAG/RANGE.
