SG Iron Casting: What is it, And What Are The applications?
SG Iron Casting, also known as Spheroidal Graphite Cast Iron or Ductile Iron, is a form of iron casting used as a high-performing engineering material in different industries. It has exceptional mechanical properties. Unlike traditional grey cast iron, this type of iron contains flake-shaped graphite. These flake-shaped graphite structures make the SG iron casting strong, hard, and tough.
You will commonly find these castings in different automotive, construction, railway and energy sector applications.
What is SG iron casting?
SG iron casting, also known as Spheroidal Graphite Iron casting, is made up of graphite that is present in a spherical form instead of the flaky form present in other types of castings. SG iron casting is strong and has high resistance to all kinds of impacts. Since magnesium or cerium is added in controlled quantities, it has a high effect on graphite morphology in the SG iron casting.
What are the key attributes of SG iron casting?
- SG iron casting is highly strong and thus ideal for carrying high volumes of loads. The nodular graphite makes it ductile and prevents it from breaking.
- SG iron casting absorbs mechanical vibrations, helping to reduce vibrations, making it ideal for machine bases, engine blocks, and heavy machinery components.
- SG iron casting is ideal because of its high impact resistance capacity. It can effectively withstand cyclic and dynamic loads.
- SG iron casting has a rust-resistant capacity, which can be increased by adding alloying elements such as nickel, chromium, and molybdenum.
Applications of SG iron casting in different industries
SG iron casting is commonly found in industrial applications because of its superior features. Some of the common industrial applications are as follows:
Automotive industries
SG iron is widely used in the automotive industry because of its durability, impact resistance, and high strength. It is also resistant to wear and tear, making it ideal for the steel industry.
Energy industry
SG iron is a crucial material for the energy industry. It is especially used in wind turbine components and power transmission hardware. This type of iron can resist fatigue and thus increase the lifespan of the equipment.
Construction industry
SG iron casting is commonly used to design and install manhole covers, structural parts, and pipes in construction projects. Its good load-bearing capacity and high rust resistance make it the ideal material for these components.
Heavy machinery
You will find SG iron casting being exclusively used in gears, hydraulic cylinders, and industrial rollers. The properties, like high resistance to wear and tear and withstand extreme working conditions, make it suitable for use in heavy machinery operating under continuous mechanical pressure.
Railway components
Components like couplings, brake discs, and axle housings are made with SG iron because it is strong and can absorb shocks. These components are subjected to high vibrations and thus should be designed to withstand the high impact forces. SG iron casting helps dampen vibrations.
