We are Manufacturer, Supplier, Exporter of Industrial Castings ( Foundry Castings ), SG Iron Castings ( Spheroidal Graphite Iron Castings ), Machined Grey & Ductile Iron Castings, Nodular Cast Iron from Kolhapur, Maharashtra, India.
SG iron casting, also known as spheroidal graphite cast iron, ductile iron, or nodular cast iron, is a type of cast iron with superior strength, ductility, and impact resistance:
SG iron is similar to gray cast iron, but it contains magnesium or cerium to create graphite nodules instead of flakes. SG iron has a higher yield strength than gray iron, is lighter than steel, and can be cast at a lower temperature. It also has excellent ductility, wear resistance, fatigue resistance, and toughness.
SG iron is used in a variety of industries, including automotive, construction, and agriculture. For example, it's commonly used in crankshafts. SG iron is produced directly from the melt, without heat treatment. Magnesium or cerium is added to the ladle just before casting.
SG Iron Grades : SGI-400/10, SGI-400/12, SGI-400/15, SGI-500/7, SGI-600/3, SGI- 700/2 & SGI- 700/3
Casting Weight Range : from 0.500Kg up to 85Kgs
