..., making possible the dephosphorization and limited desulfurization of the metal. (With some ores, phosphorous oxidation made an important contribution to the converter energy balance.) Air blowing had two important drawbacks. First, because of nitrogen’s solubility in liquid iron, the refined metal...

... chlorine is approximately 320 °C (600 ° F), with the presence of water vapor accelerating corrosion. By far, the largest family of nickel alloys is that based on the nickel-chromium system, with alloy 600 (N06600) being the prototype ( Fig. 2 ). Chromium imparts resistance to oxidizing environments...

... atmospheres are more easily applied for desulfurization. Vacuum degassing is also possible with the steel in a ladle, and argon lances can be used to stir the steel to make the composition more homogeneous. Vacuum degassing produces ultralow-carbon steels, with carbon contents as low as 0.002 wt%. This allows...
