Abstract

1. Austenitic steel having a content (in percent by weight) of chromium and nickel of in each case 14.5 to 15.5%, a carbon content of 0.08 to 0.12%, a titanium content of 0.33 to 0.55%, a manganese content of at most 2% and admixtures of silicon and molybdenum, residual iron and impurities, characterised in that the silicon content is 0.55 to 1.0% and the molybdenum content is 1.4 to 1.5%.
