Abstract

In the treatment of magnetic materials as described in the parent Specification, water vapour is added to the hydrogen or hydrogenous atmosphere, the latter being saturated with the vapour at about room temperature. The magnetic materials comprise pure iron, steel containing 0,1 per cent of carbon, or an iron-cobalt alloy containing 50 per cent of cobalt.
