FCD300LT

FCD300LT is a material in the category Cast iron. Its recorded composition includes C ≤ 3%, Mg ≤ 0.09%, Si ≤ 2.5%, P ≤ 0.05% and Mn ≤ 0.4%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include Rm 300 N/mm², Re 200 N/mm² and A 12%.

About Cast iron

Cast iron is an iron-based casting alloy whose properties depend on its composition and microstructure. It is characterised by good castability and a range of hardness, strength, and ductility, making it suitable for machine bases, housings, pipes, engine components, and wear-resistant parts.

This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Iron — the balance, never listed by a standard — 93.9 %C — 3 %Si — 2.5 %Mn — 0.4 %Traces & impurities · 0.2 %

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

Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni, Cr, Mo.

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.
