  • Metal Profile: Chromium Properties, History & More

    2019-2-3 · Aluminothermic production of high purity chromium metal accounts for over 95% of chromium metal produced today. The first step in this process requires that the chromite ore is roasted with soda and lime in the air at 2000°F (1000°C), which creates a sodium chromate containing calcine.It can be leached away from the waste material and then reduced and precipitated as chromic oxide (Cr 2 O 3).

  • Steel Effects of heat-treating Britannica

    Steel Steel Effects of heat-treating: Adjusting the carbon content is the simplest way to change the mechanical properties of steel. Additional changes are made possible by heat-treating—for instance, by accelerating the rate of cooling through the austenite-to-ferrite transformation point, shown by the P-S-K line in the figure. (This transformation is also called the Ar1 transformation

  • Abrasive Grinding Defects. Hazards Related to

    2020-5-1 · Abrasive grinding is the process of metal removal through abrasive action. Abrasive grinding is an effective method to remove material but there can be certain defects due to abrasive grinding and hazards related to abrasive grinding wheels. This article describes these defects and hazards related to abrasive grinding.

  • Effects of heat treatment on metal-ceramic

    This study was designed to evaluate the effects of heat treatment on the metal-ceramic bond strength and porcelain adherence of a Co-Cr alloy fabricated by SLM. No significant differences in the bond strength were observed for the As-SLM, SLM-880, and SLM-1100 groups, leading to the acceptance of the first null hypothesis.

  • Safety and Health Topics Hexavalent Chromium

    2020-7-9 · Hexavalent chromium [Cr(VI)] is one of the valence states (+6) of the element chromium. It is usually produced by an industrial process. Cr(VI) is known to cause cancer. In addition, it targets the respiratory system, kidneys, liver, skin and eyes. Chromium metal is added to alloy steel to increase hardenability and corrosion resistance.
