STAINLESS STEEL FOIL FOR CATALYST SUPPORT OF EXHAUST GAS PURIFIER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240011136 titled 'STAINLESS STEEL FOIL FOR CATALYST SUPPORT OF EXHAUST GAS PURIFIER

Simplified Explanation

The abstract describes a stainless steel foil that is used as a catalyst support in an exhaust gas purifier. This foil is highly resistant to diffusion bonding and brazeability, as well as oxidation at high temperatures.

• The stainless steel foil has a specific chemical composition.
• It has a parameter "sa" (surface area) ranging from 0.50 μm to 3.00 μm.
• It also has a parameter "str" (surface texture) ranging from 0.20 to 1.00 according to ISO 25178.

Potential applications of this technology:

• Catalyst support in exhaust gas purifiers for automobiles and industrial equipment.
• Can be used in various industries where oxidation resistance and high-temperature stability are required.

Problems solved by this technology:

• Diffusion bonding resistance: The foil's resistance to diffusion bonding ensures that it remains intact and does not degrade under high-temperature conditions.
• Brazeability: The foil's excellent brazeability allows for effective bonding with other components of the exhaust gas purifier.
• Oxidation resistance: The foil's ability to resist oxidation at high temperatures ensures its longevity and performance in harsh operating conditions.

Benefits of this technology:

• Improved durability and performance of exhaust gas purifiers.
• Enhanced efficiency in removing pollutants from exhaust gases.
• Extended lifespan of the catalyst support, reducing maintenance and replacement costs.
