It is suitable for solvents with boiling points in the range 30–90°C and should only be used if you are sure that your compound is thermally stable. Figure 3.

This means that steels that are very hardenable (i.e. tend to form martensite under moderately low cooling rates) have to be furnace cooled. iphone is hot
