Abstract (en)

Use of a steel alloy containing (in wt.%) 0.32-0.45 carbon, 0.8-2.2 silicon, 0.1-0.8 manganese, 0.8-1.8 chromium, maximum 0.015 nitrogen, 0.01-0.08 niobium, maximum 0.4 vanadium, 0.001-0.005 boron and a balance of iron as a material in the production of dynamically loaded tubular components is new. The tubular component has a tensile strength in the annealed state of more than 1800 MPa and a yield point of more than 1600 MPa. An independent claim is also included for a tubular component made from the above steel alloy.
