Steel that has to be bent into shape for a particular application needs a certain degree of hardness but must not be too hard to be processed. That means that it must be possible to heat the steel without creating too much additional stress. Depending on the type of steel, rolled steels from Steeltec can be bent either directly or after heat treatment. Our engineering steels can be bent or welded directly; our chain steels, in contrast, need to undergo prior heat treatment. The bending property of a steel after heat treatment is also a key factor when manufacturing springs.
