Silicon steel with a magnetic flux density B50 above 1.7 T often sees its yield strength fall below 270 MPa. Meanwhile, materials with favorable stamping workability usually require yield strength controlled under 290 MPa to prevent excessive die wear.<\/p>\n<p>When selecting materials, first clarify whether magnetic performance or mechanical strength takes priority for the equipment, then screen specific grades within the corresponding performance range.<\/p>","protected":false},"excerpt":{"rendered":"<p>I.
