Abstract

The invention is directed to a shaped body made of a metal material which ovides poor welding results and which is used especially for conduits, containers or the like for making chemical equipment for use in corrosive mediums.

To provide good corrosion-resistance for the shaped body, it is partially or completely covered with a fixedly applied material of a similar kind.
