One Minute Mentor: Austenitizing of Water-Hardening Tool Steels

Austenitizing temperatures for water-hardening tool steels normally vary from 760 to 845 °C (1400 to 1550 °F), as indicated in Table 2. Higher temperatures are sometimes used for special purposes (Fig. 2). Hardenability increases as austenitizing temperature increases. The optimum time at austenitizing temperature is from 10 to 30 min. Preheating is unusual except for very large tools or those with intricate cross sections. It is particularly important to protect shallow-hardening steels against scaling and decarburization. Severe scaling can interfere with heat transfer during quenching and slow the required high rate of cooling. Decarburization will produce a soft surface on any tool steel, but in a deep-hardening steel it can be ground off until the underlying hard high-carbon area is reached. Grinding a shallow-hardening steel will frequently expose the soft core.

ALD develops a new powder recycling process for a sustainable circular economy

ALD Vacuum Technology, Germany, has developed an additive manufacturing solution, the EBuild 850 that can process powder with a wide distribution, enabling it to be used not only in industrial-scale part production, but also in powder recycling efforts. 

Using selective electron beam melting to create powder-filled ingots, ALD achieves an unprecedented build rate of over 1000 cm³ per hour. These ingots can be seamlessly converted into new powder, for example in ALD’s EIGA Premium systems, promoting a sustainable circular economy.

ALD’s approach not only reduces waste, but also offers versatile options for downstream processes. The powder-filled solid cased ingots are much safer to handle and process than loose powder. This flexibility increases the overall efficiency of the recycling process and enables integration into established processing routes.

One Minute Mentor: Continuous Operating Furnaces for Tool Steel Strips

The continuous heat treatment of tool steel is applied to low- or medium-alloyed carbon steel strips as well as martensitic stainless steels. The described lines produce high-quality strip with respect to uniform structure, flatness, and bright surface finish. Steel grades with 0.4 to 1.2% C, low and high alloyed, can be processed. Strip dimensions range between 10 to 750 mm (0.4 to 29.5 in.) wide and 0.05 to 4 mm (0.002 to 0.16 in.) thick. High quenching rates are necessary, especially for plain carbon steels. Cooling gradients of up to 600 K/s are possible in a molten lead-bismuth quench. Because two-stage quenching technology provides considerable advantages over quenching in oil, this method has been adopted worldwide. It is also possible to achieve isothermal transformation to bainite and pearlite using a molten metal quench, so this type of hardening and tempering line is extremely versatile.

The configuration of a high-performance line involves an entry and exit section of the strip handling equipment (Fig. 10). The hardening section consists of the austenitizing furnace, the molten metal quench or hydrogen quench, and a martensite cooler. Beyond the martensite cooler the strip is martensitic and fully hardened, and then it passes through the tempering section—consisting of a leveling furnace, tempering furnace equipped with an atmosphere recirculation system, and an atmosphere jet cooler—to finally leave the facility, completely flat, with a bright surface finish and tempered to very uniform tensile strength.
