Abstract: Ferritic, stabilized, stainless and corrosion-resistant chromium-molybdenum steels with a carbon content of from 0.01 to 0.025%, a nitrogen content of from 0.005 to 0.025%, a chromium content of from 20.0 to 30.0%, a molybdenum content of from 3.0 to 5.0%, manganese and silicon contents of from 0.02 to 1.0% in each case and vanadium, tungsten, cobalt and aluminum contents of at most 0.25% in each case and also with a nickel content of from 3.2 to 4.8%, a copper content of from 0.1 to 1.0%, a titanium content of from 0.2 to 0.7% and/or a niobium content of from 0.2 to 1.0%, the rest being iron with the usual impurities, alloying additions of boron and/or zirconium being permitted in quantities which correspond to the prior art.

Abstract: A method and a capsule and a blank for producing tubes, bars or similar profiled elongated dense metal objects, preferably in stainless steel qualities, by single or multi-stage extrusion of capsules which are filled with powder of metals or metal alloys or mixtures thereof or with mixtures of powder of metals and/or metal alloys with ceramic powder and sealed and which are adapted in their form to the desired object or intermediate product, as starting material a powder being used which consists at least predominantly of substantially spherical grains and the capsule filled with said powder and sealed being compressed by means of cold-isostatic pressure acting all round until the density of the powder reaches at least 80% of the theoretical density.

Abstract: A method for producing stabilized ferritic stainless chrome steels which are distinguished in the welded state by high notched bar impact strength, wherein in powder-metallurginal manner by atomizing melts of the said chrome steels under argon a powder is produced which is pressed and agglomerated in known manner and that the pressed bodies are finally brought by hot or cold working into the desired semi-finished product form, preferably sheet form.
