About Cast steel
Cast steel is a ferrous material produced by pouring steel into moulds to form components. It combines the shape-making flexibility of casting with the strength and toughness associated with steel, making it suitable for complex, heavily loaded parts such as machinery components, structural castings and industrial equipment.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.

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.
