Abstract
A ferritic alloy, having an improved combination of magnetic properties and corrosion resistance, contains, in weight percent, about ______________________________________ % ______________________________________ Carbon 0.03 max. Manganese 0.5 max. Silicon 0.5 max. Phosphorus 0.03 max. Sulfur 0-0.5 Chromium 10-13.0 Molybdenum 0-1.5 Nitrogen 0.05 max. Titanium 0.01 max. Aluminum 0.01 max. ______________________________________ and the balance is essentially iron. The alloy, and articles made therefrom, provide higher saturation induction than known corrosion resistant, magnetic alloys.
