The American Standard AISI Ball Base Iron Castings are made with a carbon content of 0.80-1.15%, a manganese content of 0.60-1.40%, a silicon content of 0.10-0.75%, a phosphorus content of 0.035% maximum and a sulfur content of 0.040% maximum. These alloys are usually used in a wide range of general purpose and non-pressure vessel applications. AISI Ball Base Iron Castings have moderate tensile strength from 450-550 MPA and a yield strength from 250-350 MPA. This type of cast iron is not recommended for use in high temperature environments or for applications with high shock or vibration.
These castings are also not suitable for use in corrosive environments or applications requiring additional alloying elements such as chromium or nickel. However, they can be machined and fabricated easily and can be used in construction components and automotive parts. AISI Ball Base Iron Castings are machined to achieve a smooth surface finish and tight tolerance. The castings are heat-treated to remove internal stresses caused during the solidification process. Generally, these types of castings are used for their durability, strength and non-brittle characteristics.
AISI Ball Base Iron Castings are reliable and cost-effective for applications that do not require higher strength or better abrasion resistance. These castings are good choice for large parts that need a good surface finish. They are also popular for support and foundation parts, bearing journals , valve bodies and seats, machine frames and embedding components like a valve body into concrete.
Due to their moderate strength and cost-effectiveness, AISI Ball Base Iron Castings are widely used in a wide range of industries including agriculture, construction, railway and aerospace. They are used in a variety of applications such as machinery, pumps, compressors, valves and coupling housings.
In order to meet the demands of customers, a variety of castings can be tailored to custom specifications. The casting can also be designed according to the customers need for a specific melting point or mechanical properties. The castings are produced continuous-cast or green-sand. Other processes also include centrifugal or die-casting.
AISI Ball Base Iron Castings are easy to machine and maintain. The castings have excellent strength and wear and tear resistance. The surface finish of the castings can also be varied to provide a polished and anodized surface or a rough texture finish. These castings are also recyclable and are environmentally friendly.
In conclusion, AISI Ball Base Iron Castings are economic and reliable choice for general purpose and non-pressure vessel applications. They provide good strength, wear and tear resistance and a variety of customisable courses and options.
