Tool Steels for Cold or Hot Work: Steel Grades, Applications, and Manufacturing

Dear Colleagues,

To minimize the wear rate of cold and hot work tools, it is necessary to understand the factors that are related to steels’ wear mechanisms. This knowledge can be used to select the proper tool steel and thereby increase the tool life. Thus, the tribological characteristics of the metal blank surface in terms of friction coefficient depend on the blank temperature and contact pressure.

Wear mechanisms involved with tool damage on the one hand, and fatigue life on the other, are determined by factors that are directly related to the mechanical properties of the materials. The study of wear behavior in friction processes is carried out using specific tribological tests in order to characterize different tool steel grades, with and without coatings. The development of new advanced materials requires the use of advanced manufacturing technologies.

This Special Issue aims to address the tribological behavior of tool steels for cold and hot work. Papers dealing with processing techniques, modeling of the mechanical behavior, characterization of material microstructure, testing solutions, temperature dependence, as well as advanced applications are encouraged. Proposed topics are the following ones:

• Tool steel grades and characteristics
• Metallurgy of tool steels
• Wear and tribology
• Effect of chemical alloying elements, tungsten, chromium, vanadium, molybdenum, and others
• High-speed steels
• Mechanical behavior of tool steels: tensile, fatigue, and other mechanical characteristics
• Manufacturing of dies and molds
• Production with tool steels: cold and hot stamping, extruding, forming, drawing, injection, and others
• Cutting tools
• Presses, injection machines, and other equipment
• Coatings for tool steels and dies
• Additive manufacturing
• Surface integrity
• Sculptured surface machining

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
