Question about Burg Wächter Furniture safe FAVOR S5 K

The safe has no seal or special insulation. In the event of a fire, it may remain intact, but the contents will still get hot and melt or burn.

Hello Rahel
The safe is made of sheet steel. The melting point of steel is around 670 degrees centigrade.
In the description it is described as not fireproof.
