Description
Die Neuerung betrifft einen Schichtverbundwerkstoff für Münzen, Wert- und Spielmarken sowie artverwandte Gegenstände.The innovation concerns a layered composite material for coins, tokens and gaming tokens as well as related objects.
Aus der JP 4-66651 ist eine nicht rostende Chrom-Nickel-Stahllegierung als Münzwerkstoff für einlagig hergestellte Münzen bekannt, die folgende Zusammensetzung (in Masse-%) aufweist: < 0,03 % C, < 0,5 % Si, < 3 % Mn, 8 - 16 % Ni, 16 - 20 % Cr, < 0,03 % N, < 5,0 % Cu, Rest Eisen und herstellungsbedingte Verunreinigungen. Bedarfsweise können noch folgende Legierungselemente (in Masse-%) hinzugefügt werden: < 0,5 % Ti, < 0,5 % Nb, < 0,5 % V, < 0,5 % Zr, < 3 % Mo, < 1,5 % Al, < 0,03 % B.JP 4-66651 describes a rust-proof chromium-nickel steel alloy as a coin material for single-layer coins, which has the following composition (in mass %): < 0.03 % C, < 0.5 % Si, < 3 % Mn, 8 - 16 % Ni, 16 - 20 % Cr, < 0.03 % N, < 5.0 % Cu, the remainder being iron and impurities resulting from the manufacturing process. If required, the following alloying elements (in mass %) can be added: < 0.5 % Ti, < 0.5 % Nb, < 0.5 % V, < 0.5 % Zr, < 3 % Mo, < 1.5 % Al, < 0.03 % B.
Durch die EP-A 0 343 701 ist ein Schichtverbundwerkstoff zur Herstellung von Münzen bekannt geworden, der unter anderem eine Kernschicht aus einem ferritischen Chromstahl beinhaltet, die beidseitig mit einer Schicht aus einem austenitischen Chrom-Nickel-Stahl plattiert ist.EP-A 0 343 701 has disclosed a layered composite material for the production of coins, which includes, among other things, a core layer made of a ferritic chromium steel, which is plated on both sides with a layer of an austenitic chromium-nickel steel.

Häufig wurden Nickel- und bestimmte Kupferlegierungen für die Erzeugung von Münzrohlingen eingesetzt. In neuerer Zeit wird mehr und mehr der Ruf nach preisgünstigen, jedoch optisch ansprechenden Münzen laut. Im Zuge dieserNickel and certain copper alloys were often used to produce coin blanks. In recent times, there has been a growing demand for inexpensive, yet visually appealing coins.
Entwicklung sind auch schon verschiedene Arten nicht rostender Stähle zu Münzen verarbeitet worden. Eingesetzt werden vor allem der ferritische Stahl X6CM7 (deutsche Werkstoffnummer 1.4016) und der austenitische Stahl X5CrNi18. 12 (deutsche Werkstoffnummer 1.4303). Jedoch der bläuliche Farbton, insbesondere der ferritischen, nicht rostenden Stähle läßt diese visuell nicht als gleichwertig gegenüber den visuell als weiß empfundenen Münzwerkstoffen, wie Silber oder Nickel bzw. deren Legierungen erscheinen.Development has also seen the manufacture of various types of stainless steel into coins. The most commonly used steels are the ferritic steel X6CM7 (German material number 1.4016) and the austenitic steel X5CrNi18.12 (German material number 1.4303). However, the bluish color, particularly of the ferritic, stainless steels, means that they do not appear to be equivalent to the coin materials that are visually perceived as white, such as silver or nickel or their alloys.

Analog zum Stand der Technik, insbesondere gemäß DE-C 196 46 657, können Kernschichten aus den Werkstoffen X6Cr17 bzw. X5CrNi18 12 zum Einsatz gelangen, wobei dies jedoch nicht zwingend ist.Analogous to the state of the art, in particular according to DE-C 196 46 657, core layers made of the materials X6Cr17 or X5CrNi18 12 can be used, although this is not mandatory.
Überraschenderweise hat sich herausgestellt, daß ein Schichtverbundwerkstoff aus der bzw. den neuerungsgemäßen Zusammensetzungen im weichgeglühten Zustand sowohl den angestrebten optisch ansprechenden gelblichen Farbton aufweist. .Als herstellungsbedingte Verunreinigungen werden im wesentlichen folgende Elemente gesehen: Chrom, Nickel, Eisen, Mangan, Phosphor, die in entsprechenden Grenzwerten in der Legierung vorhanden sein können, jedoch bevorzugt eher nicht erwünscht sind.Surprisingly, it has been found that a layered composite material made from the composition(s) according to the innovation has the desired visually appealing yellowish color in the annealed state. The following elements are considered to be impurities caused by production: chromium, nickel, iron, manganese, phosphorus, which can be present in the alloy in appropriate limit values, but are preferably not desired.
Einem weiterem Gedanken der Neuerung gemäß ist der Schichtverbundwerkstoff als Werkstoff für die Herstellung von geprägten Münzen, Wert- oder Spielmarken sowie artverwandten Gegenständen einsetzbar.According to another idea of the innovation, the layered composite material can be used as a material for the production of minted coins, tokens or gaming tokens as well as related objects.
