  • Patent number: 10202678
    Abstract: Method for heat treating a steel component (28, 36) comprising the steps of: a) carbonitriding the steel component (28, 36) at a temperature of 930-970° C., b) cooling the steel component (28, 36), d) re-heating the steel component (28, 36) to a temperature of 780-820° C. and d) quenching the steel component (28, 36). The method comprises the step of either e) performing a bainite transformation at a temperature just above the martensite formation temperature, transforming 25-99% of the austenite into bainite at the temperature and then increasing the temperature to speed up the transformation of the remaining austenite into bainite, or f) holding the steel component (28, 36) at an initial temperature (T1) above the initial martensite formation temperature (Ms), and lowering the initial temperature (T1) to a temperature (T2) that is below the initial martensite formation temperature (Ms) but above the actual martensite formation temperature during the bainite transformation.

  • Patent number: 5964915
    Abstract: A mold having a pair of mold halves defining a mold cavity for forming a glass container. There is an inner shell of the mold and an outer shell and a gap therebetween through which cooling gas flows. Heat transfer elements on the inner shell extend laterally outwardly from the inner shell into the gap for contact by cooling gas flowing through the gap thereby to cool the inner shell. The inner shell is formed from a hard material having a working temperature substantially greater than the melting temperature of glass, a heat conductivity of less than about 15 W/m-deg K, and a capability of generating at temperatures in excess of about 500.degree. C. a protective oxide film strongly adhered to the inner shell surface.
