Taschenbuch. Zustand: Neu. Neuware -Cold work tool steel constitutes a crucial category of steel employed in the production of tools and dies for cold forming operations on sheet metals. Punches and die blocks within all stamping dies, cold heading dies for various types of bearings, as well as drawing and shearing dies, are crafted from cold work tool steels due to their exceptional form-retaining capabilities, the ability to maintain sharp edges for shearing operations, and possessing good hardenability. In this study, air-hardening grade (D2), oil-hardening grade (EN31), and water-hardening grade (EN42) steels are utilized for investigating the heat treatment of cold work tool steels. The experimental investigations focus on enhancing the mechanical properties of cold work tool steels through diverse heat treatment processes.Books on Demand GmbH, Überseering 33, 22297 Hamburg 80 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -El acero para herramientas en frío constituye una categoría crucial de acero empleado en la producción de herramientas y matrices para operaciones de conformado en frío de chapas metálicas. Los punzones y las matrices de estampación, las matrices de estampación en frío para diversos tipos de cojinetes, así como las matrices de estirado y cizallado, se fabrican con aceros para herramientas en frío debido a su excepcional capacidad para conservar la forma, mantener los bordes afilados para las operaciones de cizallado y poseer una buena templabilidad. En este estudio se utilizan aceros templados al aire (D2), al aceite (EN31) y al agua (EN42) para investigar el tratamiento térmico de los aceros para herramientas en frío. Las investigaciones experimentales se centran en la mejora de las propiedades mecánicas de los aceros para herramientas de trabajo en frío mediante diversos procesos de tratamiento térmico.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Spanisch.

Taschenbuch. Zustand: Neu. Neuware -L'acier à outils pour le travail à froid constitue une catégorie cruciale d'acier utilisé dans la production d'outils et de matrices pour les opérations de formage à froid sur les tôles. Les poinçons et les blocs de matrices de toutes les matrices d'emboutissage, les matrices de frappe à froid pour divers types de roulements, ainsi que les matrices d'étirage et de cisaillement, sont fabriqués à partir d'aciers à outils pour le travail à froid en raison de leurs capacités exceptionnelles de maintien de la forme, de leur aptitude à conserver des arêtes vives pour les opérations de cisaillement, et de leur bonne trempabilité. Dans cette étude, des aciers à durcissement à l'air (D2), à durcissement à l'huile (EN31) et à durcissement à l'eau (EN42) sont utilisés pour étudier le traitement thermique des aciers à outils pour le travail à froid. Les études expérimentales se concentrent sur l'amélioration des propriétés mécaniques des aciers à outils pour le travail à froid par le biais de divers processus de traitement thermique.Books on Demand GmbH, Überseering 33, 22297 Hamburg 68 pp. Französisch.

Taschenbuch. Zustand: Neu. Neuware -Gli acciai per utensili per lavorazioni a freddo costituiscono una categoria fondamentale di acciai impiegati nella produzione di utensili e stampi per le operazioni di formatura a freddo delle lamiere. I punzoni e gli stampi di tutti gli stampi di tranciatura, gli stampi di intestazione a freddo per vari tipi di cuscinetti e gli stampi di trafilatura e cesoiatura sono realizzati con acciai da utensili per lavori a freddo grazie alle loro eccezionali capacità di mantenere la forma, alla capacità di mantenere bordi taglienti per le operazioni di cesoiatura e alla buona temprabilità. In questo studio sono stati utilizzati acciai da bonifica in aria (D2), da bonifica in olio (EN31) e da bonifica in acqua (EN42) per studiare il trattamento termico degli acciai da utensili per lavorazioni a freddo. Le indagini sperimentali si concentrano sul miglioramento delle proprietà meccaniche degli acciai per utensili a freddo attraverso diversi processi di trattamento termico.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Italienisch.
