There are a number of things that someone looking to purchase grey castings should consider. First and foremost is foundry quality in procedures and resulting products. Since characteristics of grey iron castings rely greatly on foundry practices, finding the appropriate one will result in a consumer’s needs being met or surpassed. Carbon concentration in the casting itself is another important consideration. Common percentages for carbon amounts range from 2.5 to four percent. A carbon addition of about .1 percent in grey castings will result in a tensile strength decrease of around 2700 psi. Different foundries utilize varying casting procedures.

Green sand molding is the most common production type for castings. It is generally used to produce small or medium sized cast products, but can produce castings up to 1000 pounds. The process of shell molding is used for larger applications. With shell molding, it is possible to cool the mold that contains the heated metal. This process allows for a cleaner final product than any other means of production. Centrifugal casting is the third and final type of procedure. It’s typically used for pipe and large cylinder production and consists of water-cooled molds. Choosing a reputable foundry, that utilizes the correct process for a casting, will lead to both consumer and producer satisfaction.
