HP magnet steel is designed for use wherever high magnetic permeability or high saturation values are required. Its magnetic qualities result from careful control of sulfur and residual elements plus the special deoxidization practice, which minimizes nonmetallic inclusions. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on forming, heat treating, machining, and joining. Filing Code: CS-144.
