Flatness of steel plate
WebYour pieces may not remain as flat as the plate. That is because when steel is flattened, stresses are caught inside the metal. When the metal is cut by saw, plasma, laser, waterjet, oxyfuel, or the steel is welded, those stresses are released. That can result in the cut … Web100XF steel plate has been developed for applications where increased strength-to-weight ratios are required.
