UNITED STATES PATENT OFFICE.
ALVAH W. CLEMENT, OF CLEVELAND, OHIO, ASSIGNOR TO THE CLEVELAND BRASS MANUFACTURING COMPANY OF CLEVELAND, OHIO, A CORPORATION OF OHIO.
'ACID -R ESISTING ALLOY.
To all whom it may concern:
Be it known that I, ALvAH W. CLEMENT. a citizen of the United States, residing at Cleveland, in the county of (uyahoga and State of Ohio, have invented a certain new and useful Improvement in Acid-Resisting Alloys, (A,) of which the following is a full. clear, and exact description.
The purpose of this invention is to provide an alloy of metals which is highly resistant to acids. more particularly sulfuric acid. even though that acid be in a hot diluted condition.
Such an alloy is useful to form contain- ;ers, pumps. pipes and cocks. and other articles by which acid may be handled the same as other fluids.
The use of an alloy for such purposes, necessitates that the alloy shall be machinable and that it shall not be brittle.
The principal ingredients of the alloy which is herein proposed are iron, chromium and carbon. which latter element being present as carbids of iron and chromium.
Small quantities of silicon may be used in fusing the alloy to render the fusion more fluid. in order that it may be more easily handled. The quantity of silicon thus used is small, however, preferably less than 1 per cent. and usually varying from to of 1 per cent.
Silicon in such an alloy, has a tendency to throw the carbon present into uncombined form, that is to say, as graphitic carbon; therefore care must be taken that only small quantities be used, as usually the small quantities have substantially no effect in this particular.
In order to counteract any tendency for the silicon to throw down the carbon as graphitic carbon, a. small quantity of manganese may be used, approximately of 1 per cent.
It will be apparent that the quantity of silicon and manganese present in the alloy is quite small, and so far as the ultimate prop- Spccification of Letters Patent.
Patented Mar. 16, 1920.
Application filed July 26. 1917. Serial No. 182,910.
erties of the alloy so far as acid resistance is concerned, has very little, if any effect.
An alloy of pure iron and chromium would not be resistant to the various commercial conditions under which sulfuric acid is handled, but an alloy of chromium. iron and carbon, where the carbon exists in the alloy as carbids of chromium and iron in the proportion of substantially 60 per cent. chromium. substantially 39% to 39- per cent. of iron, and substantially to per cent. of carbon is to all intents and purposes resistant to all forms of sulfuric or similar acids.
to P of l per cent. of silicon may be added at fusion and just before pouring. to impart fluidity to the alloy.
Furthermore, such an alloy is machinable. Therefore it is suitable for acid resisting pipes. cocks, and similar devices.
It may be desirable to add to the alloy :1 small amount of molybdenum. cobalt or vanadium. these various substances mentioned, having the property of increasing the malleability and ductility of the alloy and thus rendering it easier to machine.
Havingdescribed my invention. what I claim is:
1. An acid resisting metal alloy comprising substantially 60 per cent. of chromium and substantially 39f to 39% per cent. of iron and substantially to {1-, per cent. of carbon. the carbon being present as a carbid of chromium and iron.
An acid resisting metal alloy consistingof substantially per cent. of chr0- mium, substantially 39% per cent. t 39 per cent. of iron v substantially to per cent. of carbon which is present as carbids of iron and chromium, and a small amount of an element having the property of molybdenum which in'lparts malleability to the alloy.
In testimony whereof, I hereunto afiix my
