“Stainless steel comes in two types, austenitic and ferritic,” Gwendolyn said. “It has to do with atomic structure. They both form a cube on the molecular level, but austenitic steel is face-centered. It’s a cube with an atom in each corner and in the center of each cube’s faces. Ferritic steel is body-centered, with an atom in each corner and one atom in the center of the cube.” “Austenitic steel doesn’t respond to magnets,” Radion explained.
