What is Spheroidal Graphite Cast Iron and How to Find its Suppliers?

The steel industry is vast and it is seldom easy to find a company that contributes to every market need with perfection. Some of them are not able to maintain quality in their supply and some of them fail to provide the required supply on time. There are such steel products that can be only found from some manufacturers, considering the fact that not all the companies are capable of providing quality and quantity of the products as they claim or as per your requirement. Spheroidal graphite cast iron can be put into the list of such steel products. However, you can find several companies that offer imported products from China. However, here are a few tips that will help you to find a reliable manufacturer in India, but before let’s first know about spheroidal graphite cast iron.

What is spheroidal graphite cast iron?

It is also known as the ductile iron. It is famous for its fatigue resistance, impact and wear resistance. The round graphite structure in the metal provides such characteristics to the spheroidal graphite. The product is also known as nodular cast iron.

The name spheroidal graphite cast iron has come from its making process. To make the metal stronger, the essential ingredients added is graphite or carbon. Other irons are also contained graphite, but due to the round shape of carbon, the spherical is added in the name.

The carbon required to have a specific shape as it prevents it from the blend in with the metal as flakes. Such products considered useless as the flake structure of the carbon makes the metal breakable and increases the risk of cracking. However, proper control over the casting process and adding extra ingredients the brittleness can be reduced.

Strength:

Spheroidal graphite cast iron is far superior in power compared to standard cast iron. spheroidal graphite cast iron’s tensile strength is 60,000 psi and can reach up to 1,20,000 psi, while the tensile strength of regular cast iron is only 20,000 – 60,000 psi. When it comes to the yield strength ductile iron is far ahead with 40,000 to 90,000 psi, while the yield strength of cast iron is significantly low to immeasurable.

The process that occurs in the chamber with the liquefied iron plays a crucial role. Starting with the iron, more carbon is added as the iron absorbs it into the structure. During the cooling down process of the iron, manganese, Sulphur, oxygen, and Silicon helps carbon to form into spherical graphite structures.
How to find a reliable company:

Finding the right manufacturers or spheroidal graphite suppliers is easy in this digital era. You need a company that provides up to the mark quality in the product and delivers the order on time at the pre-decided location.

You need to ensure that the company offers a wide range of composition and hardness for various applications. Companies provide critical grades heated for superior strength for a specific use. You should check all the details before you place the order.

If you are looking for spheroidal graphite exporters, then ask for the quotations from a few reputed companies. Check which one offers the best deal. However, the cost is not everything; the quality also has to be up to the mark and for that considering online reviews from various web portals where the company is listed should be considered.

Summary:

Now you know the difference between spheroidal graphite cast iron and regular cast iron. You also know the process of making spheroidal graphite cast iron. If you are looking for a company that caters to your requirement in the best possible way, considered few factors such as cost, quality and the experience of the company.
