Le fer est fabriqu\u00e9 en \u00e9liminant l'oxyg\u00e8ne et d'autres impuret\u00e9s du minerai de fer. Lorsque le fer est combin\u00e9 avec du carbone, de l'acier recycl\u00e9 et de petites quantit\u00e9s d'autres \u00e9l\u00e9ments, il devient de l'acier.<\/p>\n\n\n\n
L'acier est un alliage de fer et de carbone contenant moins de 2% de carbone et 1% de mangan\u00e8se, ainsi que de petites quantit\u00e9s de silicium, de phosphore, de soufre et d'oxyg\u00e8ne.<\/p>\n\n\n\n
L'acier est le mat\u00e9riau d'ing\u00e9nierie et de construction le plus important au monde. Il est utilis\u00e9 dans tous les aspects de notre vie, dans les voitures et les produits de construction, <\/p>\n\n\n\n

Iron is made by removing oxygen and other impurities from iron ore. When iron is combined with carbon, recycled steel and small amounts of other elements it becomes steel. Steel is an alloy of iron and carbon containing less than 2% carbon and 1% manganese and small amounts of silicon, phosphorus, sulphur and oxygen.
