Abrasion or grinding wheel is produced by casting a steel alloy containing (in wt. %) 0.4-2.2% C, 0.6-2% Si, 0.5-2% Mn, 9-16% Cr, 0-2% Mo, 0-1% Ni, bal. Fe and unavoidable impurities, is used in paper mfg. and in pulp disintegrating machinery. Pref. steel compsn. is 0.6-1.1 (esp. 0.9-1) % C, 0.6-1.5 (0.7-1.2) % Si, 0.8-1.5% Mn, 11-15 (12-13) % Cr, 0-1 (0) % Mo, 0-0.5 (0) % Ni, bal. Fe. |
