New development of hot rolled steel for enamelling

Abstract

In close collaboration with its customers, Arcelor has developed new hot rolled steel grades for single-face and double-face enamelling. These new grades, that fulfil the most stringent market requirements, are produced in several plants of the Arcelor Group. Their outstanding properties are obtained by the through-process control of precipitation phenomena, including steelmaking, hot rolling and cooling. Particular attention is paid to the addition of strengthening elements, such as Mn, Cr, and Nb, for high strength grades. The enamelling ability and the mechanical properties of these new hot rolled grades are presented in this paper.
