Description
Verwendung von austenitischen Stahllegierungen Das Patent 891399# bezieht sich auf die Verwendung austenitischer Stahllegierungen mit höchstens 0,21/o Kohlenstoff, 15 bis 30'10 Chrom, mehr als 3 bis weniger als 5010 Nickel und mehr als o#,2 bis 1,50/9, insbesondere mehr als 0,2 bis 0,5'/o Stickstoff, die außerdem bis zu 41/o Silizium, Molybdän, Kupfer, Titan, Tantal, Niob, Vanadin, Wolfram und/oder Zirkon enthalten können, wobei das Nickel ganz oder teilweise durch Kobalt ersetzt werden 'kann. Diese sich durch große Widerstandsfähigkeit gegen Korrosion auszeichnenden Stähle sind trotz des geringen Nickelgehaltes infolge des Stickstoffzusatzes stabil austenitisch, das heißt nach dem Abschrecken in einem austeriitischen Zustand, der gegen Anlaßbehandlungen bzw. Dauerglühung-en unempfindlich ist, und auch trotz hoher Festigkeit gut tiefziehf ähig. Weiterhin sind sie gut schweißbar und weisen noch weitere günstigere mechanische und technologische Eigenschaften auf als entsprechende st,ickstofffreie und weiche austeniti#s#che Legierungen.Use of austenitic steel alloys The patent 891399 # relates to the use of austenitic steel alloys with at most 0.21 / o carbon, 15 to 30'10 chromium, more than 3 to less than 5010 nickel and more than o #, 2 to 1.50 / 9, in particular more than 0.2 to 0.5% nitrogen, which can also contain up to 41 / o silicon, molybdenum, copper, titanium, tantalum, niobium, vanadium, tungsten and / or zirconium, the nickel can be wholly or partially replaced by cobalt '. These steels, which are characterized by their high resistance to corrosion, are stable austenitic despite their low nickel content as a result of the addition of nitrogen, i.e. after quenching in an austeritic state that is insensitive to tempering or permanent annealing, and can also be deep-drawn despite their high strength. Furthermore, they are easy to weld and have other more favorable mechanical and technological properties than corresponding st, nitrogen-free and soft austenitic alloys.
Es hat sich nun herausgestellt, daß diese Stahllegierungen als Werkstoff für unmagnetische Kappenringe im besonderen Maße geeignet sind. Bisher wurden als Werkstoff für solche Gegenstände austenitische Chrom-Mangan-, Mangan- und Mangan-'-i\-ick,el-Stähl-e verwendet. Diese Legierungen haben jed-och den Nachteil, daß die Streckgrenze tief liegt und daß sie hei ihrer 'Verwendung, als Werkstoff für Kappenringe zur Erhöhung ihrer Streckgrenze kalt verformt werderi müssen. Bei Verwendung der im Patent 8191 399 angegebenen Stahllegierungen werderi diese NachteiIe vermieden. Die augegebenei) Legierungeti sind unmagnetisch wid haben scboii im vergüteten Zustand die erforderliche hohe Streckgren7e. Es wurden z. B. mit einer Legierung, die 0,04 1/o Kohlenstoü, 0,33 0/0 Sil,iziuin, 0,51 0,'o 2vIangan, 22-,7 0/0 Chrom, 4,2 "/0 Nickel und 0,27 0/0 Stickstoff enthielt, nach einer Vergütung durch Uschrecken von iioo' C in Wasser folgende FestigIlleitswerte,erreicht: Streckgrenze ............. 6o,o, kg/mm2 Zugfestigkeit ............. 86,5 kg/mM2 Dehnung (5 - d) # ......... 48V0-Trotz der hohen Streckgrenze 1,zi#iiiieii hifolge der noch vorhanden,-ii hohen Dehnung die Legierungeii noch weiterhin kalt aufgeweitet werden, falls dies erforderlich sein sollte. Es wird daher bei V2rwendung dieser Legierungen als Werkstoff für unmagnetische Kappenringe die erforderliche hohe Zugfestigkeit ]),ei we-sentlich höherer -Streckgrenm# und Dehnun-, ohne oder durch weit geringere Kaltv,erforinung"erreiclit, als sie bei Verwendung der hislier gebräuchlichen Stahlsorten erforderlich ist. It has now been found that these steel alloys are particularly suitable as a material for non-magnetic cap rings. So far, austenitic chromium-manganese, manganese and manganese -'- i \ -ick, el-steel-e have been used as the material for such objects. However, these alloys have the disadvantage that the yield point is low and that, when they are used as material for cap rings, they have to be cold-deformed to increase their yield point. These disadvantages are avoided when the steel alloys specified in patent 8191 399 are used. The given alloys are non-magnetic and in the quenched and tempered condition they have the required high yield ratio. There were z. B. with an alloy containing 0.04 1 / o carbon, 0.33 0/0 sil, iziuin, 0.51 0, 'o 2 manganese, 22-, 7 0/0 chromium, 4.2 "/ 0 nickel and contained 0.27% nitrogen, the following strength values were achieved after quenching 100 ° C in water: Yield point ............. 6o, o, kg / mm2 tensile strength .. ........... 86.5 kg / mM2 elongation (5 - d) # ......... 48V0-Despite the high yield point 1, zi # iiiieii if it is still present, - ii high elongation, the alloy can still be expanded cold if this should be necessary. Therefore, when these alloys are used as a material for non-magnetic cap rings, the required high tensile strength]), much higher elongation and elongation, without or by means of far less cold hardening than is necessary when using the steel grades commonly used in the past.
