ASTM A720 Ductility of Nonoriented Electrical Steel Test Equipment

ASTM A720 is a specialized bend test for nonoriented electrical steel not covered under Test Methods ASTM E290. It covers determination of ductility utilizing Epstein test strips and a bending device for bending the strip over a predetermined radius. It is intended for commercial silicon-bearing steel sheet or strip of nonoriented types in the thickness range from 0.010 to 0.031 in. [0.25 to 0.79 mm]. The test requires a special bend test fixture.
