Ferro-alloys.

Ferro-alloys Note 1(c) to this chapter defines ‘ferro-alloys’, specifying in particular the limits of contents of non-ferrous alloy elements and of the element iron. For the classification of ferro-alloys in the subheadings of heading 7202 , see subheading note 2 to this chapter. Thus, for example, a ferro-alloy containing more than 30 % of manganese and 8 % or less of silicon is classified in...

Ferro-manganese Ferro-manganese takes the form of rough pieces with a white gleaming fracture. It is brittle and very hard. It is used for deoxidating, desulphurising and recarburising steel and, by the addition of manganese, as an alloying element.

Containing by weight more than 2 % of carbon These subheadings include those types of ferro-manganese known as high carbon (high carbon ferro-manganese). The most commonly used quality contains 6 to 7 % of carbon; the manganese content must be greater than 30 % but is generally between 70 and 80 %.

Other This subheading covers ferro-manganese with a medium (1,25 to 1,5 %) or low (less than 0,75 %) carbon content; the manganese content may vary from 80 to 90 %. Such products are used in the manufacture of manganese alloy steel requiring a low carbon content.

Ferro-silicon Ferro-silicon has a shiny grey fracture and is brittle. In trade, there are types containing from 10 % to almost 96 % silicon, with a low carbon content (0,1 to 0,2 %). It is used either for refining steel or for the manufacture of steels which contain silicon (particularly ‘electrical sheet and plate’), or (instead of silicon, which is more expensive) as a reducer...

Ferro-silico-manganese Ferro-silico-manganese, also known simply as silico-manganese, is used in various forms containing more than 8 % and up to 35 % of silicon, more than 30 % and up to 75 % of manganese and up to 3 % of carbon. Its uses are similar to those of ferro-silicon, but the combined effect of silicon and manganese minimizes the inclusion of non-metallic substances and ultimately...

Ferro-chromium Ferro-chromium takes the form of very hard crystalline masses, the crystals being sometimes very developed. It generally contains 60 to 75 % of chromium; the carbon content is 4 to 10 % in common ferro-chromium and may be as low as 0,01 % with a corresponding reduction in brittleness. It is used for producing chromium steels.

Ferro-silico-chromium Ferro-silico-chromium generally contains 30 % of silicon and 50 % of chromium and the carbon content may be high or very low as in the case of ferro-chromium. It is used for the same purpose as ferro-chromium; the presence of silicon facilitates the deoxidating of steel.

Ferro-nickel Ferro-nickel falling in this subheading contains less than 0,5 % of sulphur and is generally used as an alloying element in the manufacture of nickel steel. Ferro-nickel with a sulphur content of 0,5 % or more cannot be used in that state for the manufacture of nickel steels; it is regarded as an intermediate product of nickel metallurgy and is, therefore, classified in...

Other This subheading includes ferro-silico calcium, ferro-mangano-titanium, ferro-silico-nickel, ferro-silico-alumino-calcium, ferro-aluminium, ferro-silico-aluminium and ferro-silico-mangano-aluminium. Ferro-aluminium generally contains between 12 and 30 % of aluminium. Certain types of ferro-aluminium are sometimes used directly for the casting of special parts because of their high...
