Description

UNITED" STATES. PATENT OFFICE.
' JAMES OHUROHWARD, OF NEW YORK, N. Y.
ALLOYED STEEL.
Specification of Letters Patent.
Patented Oct.15, 1907.
Application filed April 12,1907. Serial No. 367,807.
The present invention relates to alloys of steel, and
particularly where vanadium is employed as one of the alloying metals; and the object of this invention is to produce a metal as will be hereinafter described which will be suitable for many uses and purposes.
In carrying out the present invention there is mixed with iron or steel relatively small proportions of nickel,
chromium, manganese and vanadium, and the alloy is melted and cast either in an ingot for reduction and shaping or in any particular shapes orpatterns re quircd. The carbon may be contained in a stock steel if that is used or if iron is used as stock the carbon may be added in many known ways and may vary from .20 72 up to 1.25% according to the uses to which the alloy is to be appliecL,
A suitable proportion of the several metals, for pro- (lucing an extremely tough metal with great resistance to shock will be understood from the following formula,
by weight namely c Steel, containing .60% carbon... 95.10 parts.
Nickel 3. 00 Chromium 1. 50 Vanadium 15 Manganese 25.
The percentages of the alloying metals may also be variedand still remain Withinthe broad scope of my invention, namely: Steel, containing from 20% to 1.25% carbon....- ..from.. .98. 30 parts to 91.50 parts. j Nickel 1.00 3.50 40 Chromium .50 2.50 Manganese... .15 1.00 Vanadium .05 1.50
It is believed that the alloying elements named react in a chemical manner on each other, producing molecular changes of such anature that the nickel, chromium and manganese harden and toughen and the nickel and vanadium remove or prevent brittleness .without softening the alloy. Ferro compounds of the several alloying metals may be used in lieu of the pure metals.
Having thus described my invention, I claim 1. An alloy composed of steel combined with small proportions of nickel, chromium, vanadium and manganese.
2. An alloyed steel composed of the following alloying metals in about the proportions given, namely: stool, containing 30% carbon, 95.10 parts, nickel 3.00 parts, chro- 'rninm 1.50 parts, vanadium .15 parts, and manganese .25
parts.
3. An alloyed steel containing the following alloying metals in about the proportions given, namely: stool, containing 20% to 1.25% carbon, from 91.50 LoUSJm parts; nickel, from 1.00 to 3.50 parts,'cln'omium, from .50 lo 2.50 parts; vanadium, from .05 to 1.50 parts, and manganese, from .15 to 1.00 parts.
In witness whereof I have hereunto signed my name this 11th day of April 1907, in the presence of two subscribing witnesses.
