Abstract
PURPOSE: To provide a nonmagnetic roll having high strength and stress corrosion cracking resistance and capable of applying strong electromagnetic stirring force to a slab by using an Fe-base steel contg. C, N and Ni at restricted concns. or further contg. Cu at a restricted concn.
CONSTITUTION: A nonmagnetic roll made of steel contg. 0.20W0.45% C, ≤1.0% Si, 1.0W3.0% Mn, 6.0W9.0% Ni, 15.0W19.0% Cr and 0.05W0.25% N (C+N≤0.6%) or further contg. or more among 0.2W2.0% Mo, ≤2.0% Cu, 0.05W1.00% and V 0.05W1.00% Nb is provided. In order to further enhance the stress corrosion cracking resistance of the nonmagnetic roll, it is preferable that said steel is subjected to hot working such as hot forging or hot rolling or continuously subjected to heat treatment. This roll has very low permeability and contributes electromagnetic force effectively to the stirring of the internal molten steel of a slab, so a slab of superior internal quality can be manufactured by means of the roll.
