Abstract

A method wherein a steel sheet is annealed in a non-oxidising annealing atmosphere containing 0.005-1 % of ammonia, and the sheet is immersed in a galvanising bath. The method is particularly suitable for steels containing more than 0.2 % of silicon as the oxidisable alloying element. The wettability of the steel in the galvanising bath is increased while maintaining the original mechanical and/or electrical properties of the steel.
