Strong and durable, yet\n  flexible compared to the traditional cast iron. The ductile iron grades chart\n  is crucial in choosing the suitable material for particular portable\n  industrial applications.\n<\/p>\n\n<h2>What is Ductile Iron?<\/h2>\n<p>\n  <strong>Ductile Iron<\/strong> is a cast iron that further contains small\n  amounts of added magnesium, which makes the graphite cavity or nodules in the\n  metal. This process makes the graphite structure into &#8220;spherical nodules&#8221; and\n  improves its toughness, ductility, and impact resistance.\n<\/p>\n\n<p>\n  Whereas the brittle cast iron fractures when subjected to stresses, ductile\n  iron can bend and deform, and is suitable for high-pressure and load-bearing\n  applications.\n<\/p>\n\n<h2>Ductile Iron Grades \u2013 Properties Chart<\/h2>\n<p>Listed below are major ductile iron grades and their key features.<\/p>\n\n<table>\n  <tbody>\n    <tr>\n      <td><strong>Grade<\/strong><\/td>\n      <td><strong>Strength<\/strong><\/td>\n      <td><strong>Elongation<\/strong><\/td>\n      <td><strong>Key Feature<\/strong><\/td>\n      <td><strong>Use<\/strong><\/td>\n    <\/tr>\n\n    <tr>\n      <td>60-40-18<\/td>\n      <td>Medium<\/td>\n      <td>High (18%)<\/td>\n      <td>Very ductile<\/td>\n      <td>Pipe fittings, automotive parts<\/td>\n    <\/tr>\n\n    <tr>\n      <td>65-45-12<\/td>\n      <td>Medium-High<\/td>\n      <td>Medium (12%)<\/td>\n      <td>Balanced<\/td>\n      <td>Machinery parts<\/td>\n    <\/tr>\n\n    <tr>\n      <td>80-55-06<\/td>\n      <td>High<\/td>\n      <td>Low (6%)<\/td>\n      <td>Strong &#038; durable<\/td>\n      <td>Pipes, valves, pumps<\/td>\n    <\/tr>\n\n    <tr>\n      <td>100-70-03<\/td>\n      <td>Very High<\/td>\n      <td>Very Low (3%)<\/td>\n      <td>Maximum strength<\/td>\n      <td>Heavy structural use<\/td>\n    <\/tr>\n  <\/tbody>\n<\/table>\n\n<h2>\n  Most of these properties make ductile iron grades suitable for a wide range of\n  industrial applications\n<\/h2>\n\n<p>\n  The grades corresponding to ductile iron grades are characterised on the basis\n  of their mechanical characteristics:\n<\/p>\n\n<h3>Yield Strength<\/h3>\n<ul>\n  <li>\n    The stress at which permanent deformation starts.
