Heat treatment of tool steels means several phase transformations. Every phase transformation must be described by start amount, end amount, and kinetics (change of phases depending on temperature and time). Start and end amount can be calculated with different thermodynamic software. For example, Thermocalc is well validated for tool steels. The most common method for determining the transformation kinetics of main phases (e.g. ferrite, austenite, martensite, bainite) is to use dilatometric investigations. TTT (time-temperature-transformation) diagrams obtained from dilatometer measurements can be easily implemented in HTS software. An example is shown in the figure.

Wisconsin Oven, East Troy, WI, announced the international shipment of an electrically heated small batch oven to a Canadian manufacturer of automotive components. The oven, designed for curing parts, has a maximum temperature rating of 650°F and chamber dimensions of 4’ W x 4’ L x 4’ H. Prior to shipment, the oven’s temperature uniformity of ± 10°F was verified through a nine-point profile test conducted in an empty chamber under static conditions.
The unit features patented high-efficiency panel seams for improved insulation, a 4” thick insulated floor, and two carbon steel shelves for part loading, each rated for 5 pounds per square foot. It utilizes combination airflow for optimal heating rates and uniformity, with temperature controlled by a Watlow F4T digital controller, featuring a touch screen, PID control, and Ethernet communication.
The oven also includes a process timer with an audible alarm, ensuring consistent curing and part quality.
Steel Dynamics Inc., Fort Wayne, Ind., announced leadership appointments for James Anderson and Chad Bickford. Mark D. Millett, Chairman and CEO, expressed his excitement, praising their leadership qualities and positive influence within the company. Millett highlighted their commitment to the company’s core values of safety, performance, and innovation, and their focus on prioritizing personnel.
James Anderson has been named Senior Vice President of the Long Products Steel Group, effective May 1, 2024. Anderson, who will report to Barry Schneider, President and COO, brings a wealth of experience from his previous roles, including leading the Steel Fabrication business and serving as COO of New Millennium Building Systems. His new role will see him overseeing operations that include four EAF long product steel mills and various smaller facilities, together capable of shipping nearly five million tons of steel annually.
Chad Bickford will take over Anderson’s former position as Vice President of the Steel Fabrication Group, New Millennium Building Systems. Bickford, who also reports to Schneider, transitions from his recent role managing the Butler Flat Roll Steel Division. His extensive background in steel fabrication operations and leadership, including a stint as General Manager at the Virginia steel fabrication facility, prepares him well for his new responsibilities overseeing seven manufacturing facilities across the U.S. and Mexico.
