Abstract

Abstract This invention relates to a catalytic converter for transforming polluting gases into non-polluting gases comprising a housing having an inlet for the polluting gases and an outlet for the non-polluting gases, a silver coated grill within said housing adjacent to the housing inlet, a mesh, intermediate said silver coated grill and the housing outlet, said mesh comprising an alloy base consisting essentially of from 1.0% to 1.9% silicon, from 10% to 29% chrome, from 1% to 5.1% copper, from 1.1% to 9.1% molybdenum, from 0.11% to 0.5% titanium, from 0.1% to 1.9% carbon and from 0.5% to 0.9% iron and a coating of silver or palladium on said alloy.
