Description
Stahllegierung für Spaten Spaten, die als Garten- und Feldgeräte Verwendung finden, unterliegen einem starken Verschleiß durch natürliche Abnutzung sowie durch Rostbildung.Steel alloy for spade spade used as garden and field tools find are subject to heavy wear and tear through natural wear and tear as well as through Rust formation.
Die Spaten werden bisher aus unlegiertem Stahlblech hergestellt, so daß sie durch die vorerwähnten Einflüsse je nach den Umständen bald unbrauchbar werden.The spades have so far been made of unalloyed sheet steel, see above that, depending on the circumstances, they soon become unusable due to the influences mentioned above will.
Gemäß der Erfindung wird zur Herstellung der Spaten ein legiertes Stahlblech folgender, an sich bekannter Zusammensetzung verwendet: 0,4 bis i % Kohlenstoff, i bis 2 0/0 Silicium, 0,3 bis o,8 % Mangan, i bis 3 % Chrom, 0,3 bis 0,5 % Kupfer; o,2 bis 0,3 0/0 Molybdän, im übrigen Eisen mit den üblichen Verunreinigungen.According to the invention, an alloyed one is used for the production of the spade Sheet steel of the following, known composition used: 0.4 to i% carbon, i to 2% silicon, 0.3 to 0.8% manganese, i to 3% chromium, 0.3 to 0.5% copper; 0.2 to 0.3% molybdenum, otherwise iron with the usual impurities.
Ein derartiger Stahl besitzt, in Öl gehärtet, eine Festigkeit von i 5.o kg/qmm bei einer Dehnung von 8 bis io % und einer außergewöhnlich hohen Elastizitätsgrenze. Durch Verwendung einer derartigen Stahllegierung wird die Lebensdauer der Spaten allein infolge der höheren Verschleißfestigkeit verdreifacht; außerdem können die Geräte dünner und leichter gemacht werden, ohne daß ihre Gebrauchsfähigkeit darunter leidet. Durch geringe Nickel- und Vanadingehalte kann die Legierung noch verbessert werden.Such a steel, hardened in oil, has a strength of i 5.o kg / qmm with an elongation of 8 to io% and an exceptionally high elastic limit. By using such a steel alloy, the life of the spade becomes longer tripled due to the higher wear resistance alone; in addition, the Devices are made thinner and lighter without affecting their usability suffers. The alloy can be improved even further by means of a low nickel and vanadium content will.
Eine weitere Verbesserung können die Spaten durch eine nachträgliche Verchromung erfahren; sie erhalten dadurch - wie es an sich bekannt ist - sowohl einen korrosionssicheren, unempfindlichen Überzug von schönem Aussehen, als auch eine harte, abnutzungsfeste Oberfläche. Je nach der Stärke der aufgetragenen Chromschicht wird die Lebensdauer der Spaten gegenüber unverchromten weiter ganz erheblich verlängert, zumal die Verchromung auf dem legierten Stahl besser haftet und im Falle einer Verletzung des Überzuges dann der freigelegte Grundwerkstoff auch noch nicht rostet oder sich schnell abnutzt.The spade can be further improved by adding a later Experience chrome plating; as a result, they receive - as is known per se - both a corrosion-proof, insensitive coating with a beautiful appearance, as well a hard, wear-resistant surface. Depending on the thickness of the chrome layer applied the service life of the spade is further extended considerably compared to non-chrome-plated ones, especially since the chrome plating adheres better to the alloy steel and in case of injury of the coating then the exposed base material does not rust or turn itself wears out quickly.
