At the option of the manufacturer the elements aluminium, titanium, vanadium and niobium may be added singly or in combination for grain size control purposes. Elements not quoted in table shall not be added to the steel without the agreement of the purchaser, except for the purpose of finishing the heat. For forging with an equivalent diameter or thickness >100mm the carbon content shall be agreed between purchaser and supplier.
