This material is frequently used in the formation of iron and steel products, as the main element or with other alloys, both metallic and non-metallic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Pig iron<\/h3>\n\n\n\n<p>This is&nbsp;<strong>basic crude iron<\/strong>, which is made by&nbsp;<strong>heating iron ore in a furnace<\/strong>. Inside the furnace, the iron ore chemically reacts with coke and limestone. Pig iron contains approximately&nbsp;<strong>90-95% iron<\/strong>,&nbsp;<strong>3-4% carbon<\/strong>&nbsp;and traces of other elements such as silicon, manganese and phosphorus, depending on the ore used. It is&nbsp;<strong>much harder than pure iron<\/strong>, but still&nbsp;<strong>too weak for use<\/strong>.<\/p>\n\n\n\n<p>Because of these characteristics, pig iron is considered more of a raw material than a finished or semi-finished product, and is considered only an intermediate stage in the manufacture of&nbsp;<a href=\"https:\/\/scrapad.com\/en\/materials\/iron-steel\/\" target=\"_blank\" rel=\"noreferrer noopener\">steel<\/a>&nbsp;or cast iron.<\/p>\n\n\n\n<p>Among its applications, we can summarise them mainly in three:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>As feed for the mixer<\/strong>&nbsp;from which it passes directly to the refining furnaces.<\/li>\n\n\n\n<li>As&nbsp;<strong>pig iron billets<\/strong>, ingots which, once cooled, can be stored while awaiting re-melting to produce steel or iron castings.<\/li>\n\n\n\n<li>Used for&nbsp;<strong>direct casting of castings<\/strong>, although it can only be used for items that do not have to withstand structural loads or high pressures.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Cast iron<\/h3>\n\n\n\n<p>Cast iron or cast iron is an iron-carbon alloy with a high carbon content of about 3-4%, just like pig iron. This makes it an&nbsp;<strong>extremely hard and brittle material<\/strong>, which makes it&nbsp;<strong>impossible to shape even when heated<\/strong>. On the other hand, it oxidises relatively easily. Its usefulness derives from its relatively low melting temperature.<\/p>\n\n\n\n<p>Within cast iron, we can distinguish&nbsp;<strong>soft cast iron, grey cast iron and ductile cast iron<\/strong>. White cast iron has carbide impurities that allow cracks to propagate directly. Grey cast iron has graphite flakes that deflect a passing crack and initiate countless new cracks as the material breaks. Ductile cast iron has spherical graphite nodules that prevent the crack from advancing further.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Wrought iron<\/h3>\n\n\n\n<p>Wrought iron is a&nbsp;<strong>material formed by mixing liquid iron with some slag<\/strong>&nbsp;(waste). The result is an iron alloy with a much lower carbon content (between 0.05% and 0.25%).<\/p>\n\n\n\n<p>Wrought iron is thus&nbsp;<strong>softer than cast iron<\/strong>, and also&nbsp;<strong>much less tough<\/strong>, so&nbsp;<strong>it can be heated to shape<\/strong>&nbsp;relatively easily, and is also&nbsp;<strong>less prone to rust<\/strong>&nbsp;than cast iron.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Buying and selling iron on ScrapAd<\/h2>\n\n\n\n<p>On ScrapAd you can&nbsp;<a href=\"https:\/\/scrapad.com\/en\/materials\/iron-steel\/\" target=\"_blank\" rel=\"noreferrer noopener\">buy and sell iron<\/a>.&nbsp;<a href=\"https:\/\/marketplace.scrapad.com\/es\/register\" target=\"_blank\" rel=\"noreferrer noopener\">Register for free<\/a>, post your ad, wait for other verified companies to negotiate your material and get the best price.
