Abstract
PURPOSE:To obtain a work roll for sendzmir mill, having excellent characteristics, by a procedure in which a specific amount of Si is added to a high-speed tooling steel containing Cr, Mo, W, and V, and then the steel is subjected to forging, hardening, and tempering treatments. CONSTITUTION:The steel contains 1.3-1.6% C, <0.6% Mn, 4-6% Cr, 4-6% Mo, 4-6% W, 3.5-6% V, and 1.3-2.1% Si, without containing expensive Co, as compared with the conventional high-speed steel but containing Si above mentioned percentage. The high-speed steel is then subjected to forging, hardening, and tem- peraturing treatments to manufacture a work roll for sendzmir mill. The structure consists of tempered martensite, residual austenite, and a metal carbide and is excellent in hardness, wear resistance, and toughness, as well as having good heat shock resistance and good lustrousness. Thus, the steel has excellent characteristics as roll for cold rolling mill.
