Linde LLC, Bridgewater, N.J., reports that the quality of metal parts can be improved by increasing the circulation of heat treatment atmospheres with technology that does not require fans, which can cause uneven convection.
The Voestalpine Group, Dusseldorf, announces that it is expanding from traditional steel manufacturing to 3D printing with the opening of an additive manufacturing research and development facility.
Certain anomalies in these steels that should be considered before specifying a heat-treating procedure are exemplified in the opposing injurious effects of the high and low extremes of austenitizing temperature, depending on the subsequent tempering temperature.
