Abstract
PURPOSE: To provide the titled prehardened steel withstanding a thermal shock, burning loss and seizing action due to the pouring of hot molten metal and having a long life by adding a predetermined percentage each of C, Si, Mn, Ni, W, Mo and V and specifying the value of Cr equiv.
CONSTITUTION: The titled prehardened steel consists of, by wt., 0.15W0.45% C, 0.10W1.50% Si, 0.10W1.50% Mn, 0.10W1.50% Ni, 10.00W17.00% Cr, 0.50W 2.50% 1/2W+Mo, 0.10W0.80% V and the balance essentially Fe, and it is necessary to adjust the Cr equiv. value of the steel represented by the equation of Cr equiv. =Cr-40C-2Mn-4Ni+5Si+4Mo+2W+8V+2Co-40N to ≤12.50. The steel has heat crack resistance higher than that of a conventional material, superior toughness and superior high temp. strength, and it undergoes slight seizing of molten metal.
