Description

Patented Dec. 30, 1941 WEAR RESISTING ALLOY Robert W. Schlumpf and Anderson D. White,
Houston, Tex., assignors to Hughes Tool Company, Houston, Tex., a corporation of Delaware N Drawing.
Application November 10, 1941,
Serial No. 418,540
2 Claims.
The invention relates to ferrous alloys designed to be employed in constructing devices which must resist abrasion.
The invention is designed for use in the formation of devices which are subjected to rapid wear, as in the construction of sand blast nozzles, well drill nozzles, and similar devices. In such cases the material of the nozzle is subjected to repeated impact of grains of hard material, such as sand and the like, and must resist wear.
It has been found by test that objects made of this alloy are exceptionally hard and abrasion resistant. The metal is not malleable, however, but is designed to be cast in the shape in which it is to be used.
In the production of our improved alloy we employ ingredients fused together in approximately the following proportions:
Per cent Carbon 1.50- 4.50 Manganese 0.50- 1.50 Silicon 0.50- 2.00
Chromium 25.0 -35.0 Molybdenum 3.00 3.00 Iron Balance to make up 100 Per cent Carbon 3.88
Manganese 1.08
. Silicon 1.49
Chromium 32.3
Molybdenum 5.80
Iron "Balance to make up 100 It will be understood that our improved alloy may be employed in the construction of any device which may be cast into the desired shape and in which the device is not subjected to a great amount of shock or impact which may lead to fracture. It is particularly resistant to abrasion and wear.
What we claim as new is:
1. A hard abrasion resisting ferrous metal alloy, comprising the following ingredients fused together in approximately the proportions stated below:
Per cent Carbon 1.50- 4.50 Manganese 0.50- 1.50 Silicon 0.50- 2.00 Chromium 25.0 -35.0 Molybdenum 3.00- 8.00 Iron Ba1ance to make up 2. A cast ferrous hard metal object made up of ingredients alloyed together in appropriately the following proportions:
Per cent Carbon 3.88 Manganese 1.08
Silicon 1.49
Chromium 32.30
Molybdenum 5.80
Iron 55.45
