HIGHLY STABLE, STEEL AND STEEL STRIPS OR STEEL SHEETS COLD-FORMED, METHOD FOR THE PRODUCTION OF STEEL STRIPS AND USES OF SAID STEEL

摘要

A steel strip or sheet steel having good cold formability and high-strength is described, comprising a light steel having (in weight-percent) C: <= 1.00 %, Mn: 7.00 - 30.00 %, Al: 1.00 - 10.00 %, Si: > 2.50 - 8.00 %, Al + Si: > 3.50 - 12.00 %, B: > 0.00 - < 0.01 %, as well as alternately Ni: < 8.00 %, Cu: < 3.00 %, N: < 0.60 %, Nb: < 0.30 %, Ti: < 0.30 %, V: < 0.30 %, P: < 0.01 %, with the remainder iron and unavoidable impurities.
