One Minute Mentor: Transformation behavior of Austenite

The transformation behavior of retained austenite in M2 steel was examined under varying tempering conditions. The steel was initially subjected to interrupted quenching at 105 °C (225 °F), a process that elevated the retained austenite content to approximately 55 vol %, compared to the typical 25 vol % observed after direct quenching to room temperature. This was followed by tempering at 565 °C (1050 °F), without intermediate cooling. Results indicated that double tempering was significantly more effective than single tempering at transforming retained austenite under these conditions. Furthermore, repeated tempering cycles accelerated the complete transformation of retained austenite, achieving full conversion in a shorter total processing time than single-stage tempering.

One Minute Mentor: High-Performance Line

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. 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. The hardening section consists of the austenitizing furnace, the molten metal quench or hydrogen quench, and a martensite cooler.

One Minute Mentor: Salt Bath Nitrocarburizing

Salt bath nitrocarburizing is usually performed at temperatures between 560 and 580 °C (1040 to 1075 °F) in cyanate- and carbonate-containing salts with traces of cyanides and furnaces similar to those used for the nitrocarburizing of mechanical compounds. These conditions fit well with the usual tempering temperatures of hot-work tool steels, which form the main field of application of salt bath nitrocarburizing in tooling with treatment times of 15 min to 2 h.

 To guarantee a good reproducible nitriding performance, the cyanate content must be kept at approximately 35% to achieve a full ε-nitride compound layer, which today is usually done by adding a regenerator. The advantages of salt bath nitrocarburizing can be found in the very homogeneous temperature distribution, the fast formation of thick compound layers that give good tribological and corrosion properties, its high flexibility, and he fact that it does not require that any special attention be given to passivation effects. Extrusion dies are regularly treated several times during use to restore the nitride layer at areas of heavy wear.

More recently special salt compositions were developed for lower nitrocarburizing temperatures, which are essential for cold-work tool steels that do have lower tempering temperatures.
