Description

Patented July 23, 1935 UNITED STATES ALLOY Lorenzo S. Guetti, Athol, Mass.
No Drawing. Application March 12, 1935, Serial No. 10,653
1 Claim.
The present invention relates to improvements in alloys, and is more particularly concerned with the production of a stainless alloy having exceptional resistance to corrosion from any medium with which it may be brought into contact.
The alloy lends itself admirably to various methods of handling, and when cast or otherwise formed may be given a smooth, lustrous finish with a mirror-like surface. The tensile strength is adequate for normal purposes, and by varying certain of the constituents it may be made exceedingly hard if so desired. However, its principal use is in connection with utensils and implements of a widely varied character, where its inherent protection against corrosion, stains and the like make it of particular utility.
I have found in actual practice that an alloy having the following constituents within the given proportions is admirably adapted for the The elements as indicated in the table are capable of completely combining into a homogeneous, tough alloy which may be cast, machined and polished to produce a high lustrous finish which cannot be stained or marred by any known materials with which the article is likely to come in contact.
Although not limited to this class of article, I may point out that the alloy is particularly suited for cooking utensils, due to the brilliant and lasting finish which may be given it, and its freedom from stains which otherwise occur in use. The alloy has excellent heat conducting properties, and is not frangible or breakable in use.
What is claimed is:
A stainless alloy suitable for casting and consisting of nickel to chromium 10 to 30%, steel not exceeding 12%, tungsten .3 to 4%, and
cobalt .2 to 2%.
