Definitions
- the present invention relates to a system comprising a substrate and a catalytic material and to the alloy from which the substrate is formed.
- Ceramic substrates do not have the mechanical properties; e.g., shock resistance, of metallic substrates. Ceramic substrates are, in addition, inherently thicker than are metallic substrates.
- a particular metallic substrate is described in United States Patent No. 3,920,583. It is a ferritic stainless steel which contains up to 15% chromium, 0.5% to 12% aluminium and 0.1 to 3% yttrium.
- Yttrium is an expensive material which is not presently available in abundant quantities, and a material characterized by a low recovery rate during melting.
- the present invention relates to a substrate wherein the yttrium level of Patent No. 3,920,583 is significantly reduced. It has been determined that high quality substrates can be produced from iron-chromium-aluminium alloys having less than 0.1% yttrium.
- the present invention provides a system comprising a ferritic stainless steel substrate having a tightly adherent oxide coating and a catalytic material thereupon, said ferritic stainless steel being of a chemistry which forms a tightly adherent non-spalling scale suitable for application of a catalytic bearing material; characterized in that the ferritic stainless steel substrate consists essentially of, by weight, up to 26% chromium, from 1 to 8% aluminium, between 0.01 and 0.1% yttrium, up to 0.1% carbon, up to 2% silicon, balance essentially iron.
- the present invention further provides a ferritic stainless steel consisting essentially of, by weight, up to 26% chromium, from 1 to 8% aluminium, between 0.01 to 0.1% yttrium, up to 0.1% carbon, up to 2% silicon, balance essentially iron.
- the substrate is in most instances of a thickness of from 0.0127 to 0.254mm (0.0005 to 0.01 inch).
- Chromium may be present within the substrate or steel of the present invention as it is known to improve oxidation resistance. A maximum limit is placed thereupon as chromium is expensive and renders the alloy more difficult to process. Chromium is usually present within the range of from 5 to 22%, and preferably within the range of from 12. to 20%.
- Aluminium is present as it improves the oxidation resistance of the substrate or steel. A maximum limit is placed thereupon as aluminium, like chromium, is expensive and renders the alloy more difficult to process. Aluminium is preferably present within the range of from 3 to 6%.
- Yttrium is present as it stabilizes the aluminium- bearing scale and makes it both tight and adherent. It is preferably present in amounts between 0.03 to 0.09%.
- Carbon and silicon are preferably maintained at respective maximum levels of 0.03 and 0.5%.
- ferritic stainless steels have inherently high transition temperatures, which rise with increasing carbon levels, low carbon contents should be specified in order to obtain a more ductile material.
- the present invention is not dependent upon any particular means for manufacturing the catalytic system described herein.
- the system can be produced in accordance with the teachings of heretofore referred to United States Patent No. 3,920,583, or by any other process known to those skilled in the art.
- Platinum, palladium, irridium, rhodium, and alloys thereof, are typical catalytic materials.
- the catalyst serves to provoke oxidation of partially oxidized hydrocarbons; e.g., CO to CO 2 .
