Wir schweißen und beeinflussen Konstruktionen in der ganzen Vielfalt der Werkstoffwelt, wie warmfeste Stähle (C 22.8, 13CrMo44, 10CrMo910, P91,...)

• Austenitische Stähle und Duplexstähle ( 1.4571, 1.4462,...)
• Nickelbasislegierungen (2.4602, ..2.
• Nichteisenmetalle (Aluminium, Magnesium, Kupfer, CuCrZr,...)
• Hochschmelzende Metalle (Wolfram, Molybdän,...)
• Materialkombinationen (Titan-Platin, Stahl-Kupfer, Molybdän- Stahl, Silber-Kupfer , Edelstahl-warmfeste Stähle, 42CrMo4 mit St 52-3,...)

Wir härten die Randschicht von Stählen mit einem Kohlenstoffgehalt >= 0,3%. Elektronenstrahlhärten mit einer Eindringtiefe in die Oberfläche von 0,3 bis 1,5 mm. Härten von ca. 60 HRC je nach Werkstoff. Wir benötigen keine Abschreckmittel. Die Abschreckung funktioniert durch den Temperaturunterschied zwischen der mit dem Elektronenstrahl beaufschlagten Oberfläche und dem dahinter liegenden Material. Materialien wie

• 42CrMo4
• C 45
• GGG 60

sind unser Standard.
