About Heat-resistant cast steels
Heat-resistant cast steels are cast ferrous alloys formulated for service at elevated temperatures, where resistance to softening and thermal degradation is important. They are used for furnace components, heat-treatment equipment and other high-temperature plant parts that require cast shapes and dependable mechanical performance during heating.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other.

Predicted transformation temperatures
This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here.
Physical & mechanical properties
An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material.
