|Nodular iron is also called nodular cast iron, ductile iron and spheroidal graphite cast iron.
Nodular iron is handled through the graphite ball and inoculated by spherical graphite. Nodular iron has effectively improved the mechanical properties, in particular, improve the ductility and toughness, which is higher than is the strength of forged steel.
The fifties of the 20th century, nodular iron has been effectively developed as a high-strength cast iron material, the overall performance close to forged steel. Based on its excellent performance, nodular iron has been successfully used to cast a number of complex stress, strength, toughness, wear requirement of higher parts. Rapid development of nodular iron has made nodular iron widely used in many civil and industrial areas. Forged steel is gradually replaced by nodular iron.
Nodular iron castings almost cover all major industrial sectors. They have been applied in these sectors that require high strength, ductility, toughness, wear resistance, resistance to severe thermal and mechanical shock, high temperature or low temperature, corrosion resistance and dimensional stability. To meet the conditions of use of these changes, many of the existing grade nodular iron, Srixon Golf Gloves mechanical properties and provides a rational to a kiss a wide range.
Compared with grey cast iron, ductile cast iron in strength has an absolute advantage. The tensile strength of nodular iron is 60k, while the tensile strength of grey cast iron is only 31k. The yield strength of nodular iron Srixon Golf Glove is 40k, but grey cast iron does not show the yield strength, and eventually be broken. Strength nodular iron - cost ratio 3m Greptile Grip Golf Glove far superior to grey cast iron.
The strength of nodular iron and steel strength is comparable. Nodular iron has higher yield strength, yield strength minimum of 40k, while the yield strength of steel is only 36k. In most municipal applications, such as: water, salt Men S Golf Gloves water, steam, cast iron corrosion resistance and G Fore Golf Gloves oxidation resistance of more than steel.
Because of the spherical graphite cast iron microstructure, the decrease vibration capability, nodular iron is better than cast steel and forged steel, therefore more conducive to reducing stress. Low cost and better performance are the main reason to choose nodular iron than steel. Low-cost iron makes the material more popular, casting more efficient, less the cost of nodular iron machining.
For the material degrees of nodular iron, please check the standard of ASTM A536, or the comparison table for DIN, ISO, ASTM and GB.
