How important is sheet and plate steel flatness? - Know More

Mar 14, 2002 0183 32 Steel has the tendency to cling to its original shape and molecular composition Why? Because it was given a unique configuration when it was rolled, cooled, and coiled at the steel mill In its natural state, steel is not at all flat In fact, a hot-rolled sheet coil generally reveals some or all symptoms of poor flatness see Figure 1...
