1.\u00a0<\/span><\/strong>Einf\u00fchrung in M4-Materialien<\/span><\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 M4 ist ein Schnellarbeitsstahl mit hohem Kohlenstoffgehalt und hohem Vanadiumgehalt. Er hat die Vorteile einer geringen Karbidunebenheit und einer hohen Z\u00e4higkeit und ist anf\u00e4llig f\u00fcr \u00dcberhitzung. Daher sollte die Abschreck- und Erw\u00e4rmungstemperatur streng kontrolliert werden, und die Anforderungen an den Schutz bei der W\u00e4rmebehandlung sind streng. M4-Schnellarbeitsstahl hat aufgrund seiner guten H\u00e4rte und Verschlei\u00dffestigkeit eine hohe Karbidneigung, so dass strenge Anforderungen an den W\u00e4rmebehandlungsschutz gestellt werden und er sich f\u00fcr Formen eignet, die Vibrationen und Sto\u00dfbelastungen standhalten m\u00fcssen.<\/span><\/p>\n
