being preferred material for demanding applications in industries.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_Spheroidal_Graphite_Cast_Iron\"><\/span>What is Spheroidal Graphite Cast Iron?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Spheroidal graphite cast iron (or ductile iron) is a high-strength material formed through the addition of magnesium to molten cast\u2002iron. It does so by adding some minerals to the melt, causing the graphite in the cast iron to\u2002form as spheres (nodular) when solidified, as opposed to the normal flake structure seen in standard grey cast iron. The result is\u2002a hybrid material, combining the castability of cast iron, with the mechanical performance of steel, making it more versatile and tougher than grey cast iron.<\/p>\n<p>These structures in spherical graphite help avoid gray cast\u2002iron&#8217;s brittleness and help the SG iron disperse and absorb stress better than the former. Such properties have led to its usage in a variety of high strength, toughness\u2002and wear-resistant applications.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter wp-image-7310\" src=\"https:\/\/jinsuncarbon.com\/wp-content\/uploads\/2025\/01\/Spheroidal-Graphite-.jpg\" alt=\"Spheroidal Graphite \" width=\"557\" height=\"370\" srcset=\"https:\/\/jinsuncarbon.com\/wp-content\/uploads\/2025\/01\/Spheroidal-Graphite-.jpg 1024w, https:\/\/jinsuncarbon.com\/wp-content\/uploads\/2025\/01\/Spheroidal-Graphite--300x199.jpg 300w, https:\/\/jinsuncarbon.com\/wp-content\/uploads\/2025\/01\/Spheroidal-Graphite--768x510.jpg 768w, https:\/\/jinsuncarbon.com\/wp-content\/uploads\/2025\/01\/Spheroidal-Graphite--18x12.jpg 18w, https:\/\/jinsuncarbon.com\/wp-content\/uploads\/2025\/01\/Spheroidal-Graphite--600x398.jpg 600w\" sizes=\"(max-width: 557px) 100vw, 557px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_is_Spheroidal_Graphite_Cast_Iron_Made\"><\/span>How is Spheroidal Graphite Cast Iron Made?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>SG iron is produced through\u2002a process called &#8220;nodulizing&#8221; or &#8220;ductilizing.&#8221; During\u2002this process, we add small amounts of magnesium (or sometimes cerium) to molten cast iron. It reacts with carbon in the iron, making the graphite\u2002spheroidal.<\/p>\n<p>The casting process is closely regulated and demands excellent performance when it comes to\u2002managing temperature and chemical composition. This process\u2002generally consists of the following steps:<\/p>\n<ul>\n<li>Melting<\/li>\n<li>Addition of Magnesium<\/li>\n<li>Casting<\/li>\n<\/ul>\n<p>The castings\u2002can then be machined into the proper shapes. With superior tensile strength, ductility, and fatigue resistance over conventional gray cast iron, the finished product will possess\u2002improved mechanical properties.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"SG_Iron_vs_Traditional_Cast_Iron\"><\/span>SG Iron vs. Traditional Cast Iron<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Spheroidal_Graphite_Cast_Iron_Composition\"><\/span>Spheroidal Graphite Cast Iron Composition<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Spheroidal graphite cast iron is usually\u2002made of iron, <a href=\"https:\/\/jinsuncarbon.com\/hi\/uses-of-carbon\/\">carbon<\/a>, silicon, manganese, sulfur, and phosphorus. The main differentiation between SG iron and non-made SG is the coinage of magnesium or\u2002other nodulizing representatives, which result in graphite forming as round nodules. This leads to better properties of the material, especially regarding strength, toughness,\u2002and wear resistance.<\/p>\n<p>Gray cast iron, alternatively, has a graphite microstructure\u2002in flaky form. Gray Cast Iron is\u2002easy to cast and has good machinability, but its flake graphite structure makes it relatively brittle and prone to fracture under stress. The spherical graphite structure, in the case of SG iron results in significantly enhanced mechanical properties, especially concerning\u2002tensile strength and fatigue property.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Difference_Between_Gray_Cast_Iron_and_Spheroidal_Graphite_Cast_Iron\"><\/span>Difference Between Gray Cast Iron and Spheroidal Graphite Cast Iron<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Microstructure: In gray cast iron, the graphite structure consists of large, angular <a href=\"https:\/\/jinsuncarbon.com\/hi\/product\/flake-graphite\/\">flakes<\/a>. This leads to inferior mechanical properties such as lower tensile strength and\u2002low ductility. Unlike with cast, SG iron has\u2002spheroidal- or nodular-shaped <a href=\"https:\/\/jinsuncarbon.com\/hi\/what-is-graphite-and-what-is-graphite-made-of\/\">graphite<\/a>, giving it a better stress distribution than cast and preventing the brittleness associated with it.<\/p>\n<p>Strength: SG iron has considerably greater tensile strength than gray cast\u2002iron. Gray cast iron is indeed useful in non-load-bearing applications, but is more likely\u2002to crack under stress.<\/p>\n<p>Ductility: Because the graphite nodules are\u2002spherical, SG iron is significantly more ductile than gray cast iron; i.e., it can absorb much more deformation under stress without cracking. Gray cast iron, on the other hand, with its flaky graphite makes it more brittle and leads to early onset\u2002of cracking under tensile stress.<\/p>\n<p>Applications: Due to its casting prowess, SG iron is perfect for high-stress environments such as those\u2002found in automotive components (e.g. engine blocks and crankshafts), heavy machinery, and pipe systems. Because of its brittleness, gray cast iron is more commonly utilized\u2002for non-critical strength and ductility applications such as machine bases, cookware, and decorative items.<\/p>\n<h2><\/h2>\n<h2><span class=\"ez-toc-section\" id=\"Types_of_Spheroidal_Graphite_Cast_Iron\"><\/span>Types of Spheroidal Graphite Cast Iron<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h2><span class=\"ez-toc-section\" id=\"Spheroidal_Graphite_Iron_Grades\"><\/span>Spheroidal Graphite Iron Grades<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are several grades of SG iron, which have different\u2002mechanical properties and are used for different purposes.
