Abstract

PURPOSE: To provide steel for break disk excellent in resistance to cracking, by addition with Co, SiO, Mn, Ni, Cr, Mo, in addition with one or more members among sol. Al, V in prescribed ratios respectively.
CONSTITUTION: Said steel for break disk contains 0.30W0.40% Co, 0.15W0.60% SiO, 0.50W1.40% Mn, 1.50W3.00% Ni, 0.60W1.50% Cr, 0.15W0.80% Mo, in addition, 0.015W0.060% sol. Al, 0.05W0.30% V. Because P and S are deteriorating impurities to said steel, they are preferably decreased to quantities as small as possible. Said steel for break disk is excellent in resistance to cracking compared with conventional steel.
