However, ultralow-temperature (ULT) refrigeration has not been included, which commonly uses refrigerants with very high GWP values (such as R23 and R508B). Therefore, publicly available research programs seeking low GWP alternative refrigerants do not cover this application and the transition to more environmentally friendly fluids is slowed down.

Slow cooling also leads to high levels of retained austenite (up to 30 percent). Properties were determined for microstructures equivalent to those developed through air cooling and tempering of 2.5, 5.0, 10.0 and 15 cm thick plates. Simulated slow cooling was performed on small specimens to model the thicker sections.
