Abstract
High strength steel tube is made from a full hard, cold rolled steel sheet having a chemistry compliant to S.A.E. J 403 grade 1026. The high strength of the tube is a result of specified thermal-mechanical processing of hot rolled sheet followed by controlled percent cold rolled reduction, and does not require post-welding thermal heat treatment and/or cold drawing processing.
