SPCC Steel yog dab tsi?
SPCC steel yog hais txog hom txias-dov hlau, thiab nws sawv cev rau "Steel Plate Cold Commercial." Nws yog tus qauv kev lag luam Nyij Pooj (JIS G 3141) siv los txheeb xyuas cov yam ntxwv ntawm cov khoom siv txias-kuav los tiag carbon steel nplooj ntawv thiab strips. SPCC steel paub txog nws qhov zoo tshaj plaws formability, du nto tiav, thiab zoo ib yam thickness.
