Slabs

Slabs are an end product of a long and complex process chain and account for up to 60% of downstream quality in rolling. This is why the chemistry, homogeneity and surface quality are essential for slabs and a point of pride for NLMK.

These advantages are achieved at specific stages of the production cycle — from iron ore beneficiation to BF and BOF operations, where the chemical composition is secured, through to the continuous casting machine that forms the microstructure and slab geometry. NLMK’s strict quality controls at each transformation stage ensure high customizability and low tolerances that enable the production of dozens of steel grades.

A part of these semi-finished goods are consumed by NLMK’s downstream operations where high value-added products are made. The other part — with strict pre-set chemical and structural parameters — is shipped to consumers as high-quality input for strip and plate production.

Rolled products made from NLMK slabs find their application in such areas as car manufacturing, critical components in mechanical engineering and housing infrastructure, building materials, etc.
