The oxidation resistance of the different alloys in different protection and combustion gases is listed under the heading ”Heat resistance”.

The selection of a material for a given application is, in addition to its heat resistance, also determined by its availability in different product forms as well by its cost.

Thermalloys selects and supplies materials and component designs in such a way, that the life cycle cost is minimized.
