Seco/Vacuum, Pa., has shipped a single chamber high-pressure quench vacuum furnace, the Vector, to be utilized for a variety of heat-treating processes, including hardening of tool steels as well as high vacuum sintering and annealing.

Lindberg/MPH, MI, has announced the shipment of one gas-fired Exothermic atmosphere generator to the manufacturing industry.This exothermic generator features an energy efficient design that provides reliable and economic operation.

Preheating normally is employed as a safeguard against the cracking and extreme distortion resulting from the thermal shock undergone by a cold workpiece when it is exposed to the high temperature of the austenitizing furnace.

Steel Dynamics, Fort Wayne, Ind, announced that it will construct and operate a 650,000-tonne low-carbon, recycled aluminum flat rolled mill, with two supporting satellite recycled aluminum slab centers. The capital investment is estimated to be $2.2 billion for the three facilities, and commercial production is planned to begin in the first quarter 2025.

Constellium, Paris, has received a Platinum rating from EcoVadis, a leading provider of business sustainability ratings, for a consecutive time. EcoVadis places the company in the top 1% of the 90,000 companies assessed worldwide.

Nitrex Vacuum, Quebec, recently shipped a new large vertical vacuum furnace to a major aircraft engine maintenance, repair, and overhaul facility in South America. The system was purchased to modernize the plant, meet quality standards and accreditations, and produce specially designed recipes.

Austenitizing is the most critical of all heating operations performed on tool steels. Along with quenching it will usually be referred to as the hardening step in tool steel heat treatment and, associated with tempering, will be responsible for the final properties.
