Cast iron, 'Cast iron' is defined in the Concise Oxford Dictionary as 'a hard alloy of iron, carbon and silicon cast in a mould'. According to New Lexicon Webster's Dictionary of English Language, the word 'cast iron' means 'an iron-carbon alloy produced in a blast furnace. It contains up to 4% carbon, and is more brittle, but more easily fused, than steel'. According to Van Nostrand's scientific Encyclopedia, 'cast iron' is 'primarily the product of remelting and casting pig iron'. (Interestingly, the expression 'cast-iron' - with a hyphen between 'cast' and 'iron' - has been defined separately as meaning 'made of cast iron', Bengal Iron Corpn. v.

Cast iron casting in its basic or rough form just be held to be 'cast iron'. But, if thereafter any machining or polishing or any other process is done to the rough cast iron casting to produce things like pipes, manhole covers or bends, these cannot be regarded as 'cast iron casting' in its primary or rough form, but products made out of cast iron castings, Vasantham Foundry v.
