Abstract

There is provided an improved reinforced corrugated thin stainless steel strip in which either or both of the longitudinal edges are overfolded to increase the thickness and stiffness of the foil to better resist the tendency to failure in a severe hot-shake screening test. There is also provided a core and an electrically heatable catalytic converter containing the core for use in the exhaust line of an internal combustion engine.
