Maraging Stahl



Maraging Stahl

Marraging Stahl zeichnet sich durch hervorragende mechanische Eigenschaften aus, und kann unter Wärmebehandlungen unterzogen werden, um optimale Härte und Beständigkeit zu erlangen.
Das Erzeugnis kann nachbearbeitet und durch einen 6 Stunden langen Härtungsprozess bei Temperaturen bis 490 °C bis zu 50 HRC gehärtet werden.
Das Werkstück kann, falls notwendig, geschweißt, dem Drahterodieren oder der Feinstrahlung unterzogen, poliert oder beschichtet werden.
