EAF Quality Capability Trends By Steel Product Type

Electric arc furnace (EAF) capability has undergone significant evolution over the past several decades, particularly in terms of steel quality capability. This page presents a comprehensive analysis of the "technology creep" phenomenon in EAF steelmaking from 1980 to 2010, tracking the expanding market acceptability of EAF-produced steel across various product categories.

The trend analysis shows market acceptability over time for a wide range of steel products including rebar, rail, wire rod, structural shapes, plate, hot and cold rolled sheet, galvanized sheet, automotive body sheet, and tinplate. The data reveals how EAF technology has progressively overcome quality limitations that once restricted its use for certain high-specification applications.

Perhaps most notable is the remarkable progress achieved in expanding EAF acceptability for flat products such as hot and cold rolled sheet, plate, and structural shapes. These advancements stand in stark contrast to the relatively modest improvements in EAF suitability for automotive-grade sheet steel and tinplate, where more demanding quality specifications continue to present challenges for scrap-based steelmaking routes.
