Was ist Toughness?
Unter dem Begriff Toughness, übersetzt als Zähigkeit, verstehen wir in der Stahlproduktion und im Stahlhandel eine wichtige Materialeigenschaft. Sie definiert, wie gut ein Stahlprodukt extreme Belastungen aushält, ohne zu brechen. Dabei ist nicht nur die reine Kraft entscheidend, sondern auch, wie lange das Material dieser Belastung standhält.
Der Zusammenhang zwischen Toughness und Stahlprodukten
Die Toughness spielt eine wichtige Rolle in der Beurteilung der Qualität von Stahlprodukten. Stahl, der eine hohe Toughness aufweist, ist widerstandsfähiger gegen Risse oder Brüche. Das ist vor allem dann wichtig, wenn es um die Herstellung von Baustahl für Hochbauten oder Brücken geht. Aber auch bei Produkten wie Auto-Karosserien oder weißer Ware, wie Waschmaschinen oder Kühlschränken, spielt die Zähigkeit des Stahls eine wichtige Rolle.
Toughness messen und bewerten
Die Toughness eines Stahlprodukts wird in speziellen Tests ermittelt. Ein gängiges Verfahren ist der Kerbschlagbiegeversuch. Dabei schlägt ein Pendel an einem präparierten Stahlstück an. Anhand von Werten wie der Energie, die das Pendel nach dem Anschlag noch besitzt, oder der Verformung des Stahlstücks, kann auf die Toughness geschlossen werden. Vorsicht ist jedoch geboten, denn die Zähigkeit nimmt ab, wenn der Stahl unter einer bestimmten Temperatur getestet wird. Daher wird auch oft von der Bruchzähigkeit bei einer bestimmten Prüftemperatur gesprochen.
Fazit zur Toughness in der Stahlproduktion und im Handel
Zusammenfassend lässt sich sagen: Die Toughness ist eine zentrale Materialeigenschaft, wenn es um die Qualität von Stahlprodukten geht. Der Wert für die Toughness gibt Aufschluss darüber, wie belastbar der Stahl ist und in welchen Bereichen er eingesetzt werden kann. Eines ist dabei klar: Je höher die Toughness, desto widerstandsfähiger der Stahl.
