Use of a non-magnetic alloy having high hardness for electromagnetic stirrer rolls

摘要

An alloy comprising, by weight, 0.1-0.6% C, up to 2% Si, 5-15% Mn, 5-15% Cr, 5-13% Ni, 1-3% V, and at least one of up to 1% Mo and up to 2% Nb, the balance being substantially Fe and inevitable impurities. The alloy has an outstanding non-magnetic property of up to about 1.004 in magnetic permeability and high hardness of above about 215 in Vickers hardness and is useful for electromagnetic stirrer rolls for continuous casting equipment.
