Influence of Metallurgical Parameters on the Coercive Strength of Some Carbon Steels
The final properties of a wire rod for magnetic components are strongly influenced by the specific steps of the industrial cycle which can be different according to the specific chemical composition of the steel. In this experimental work, measurements of coercive strength have been carried out on wire rods in different metallurgical conditions. The influence of work-hardening, as a function of some different drawing ratios, and the restoring of the coercive strength within the accepted values by heat treatments have been investigated. The carbon content and the steel chemical composition have also been evaluated. The obtained results give important information to the wire rods manufacturers for the respect of the technical delivery conditions.
