What is the properties of cast iron?

A few common mechanical properties for cast iron include: Hardness – material’s resistance to abrasion and indentation. Toughness – material’s ability to absorb energy. Ductility – material’s ability to deform without fracture.

What kind of metal is cast iron?

Cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus.

What are the different grades of cast iron?

The 4 Types of Cast Iron

• #1) Gray Cast Iron. The most common type, gray cast iron features a graphite microstructure consisting of many small fractures.
• #2) White Cast Iron. While not as common as gray cast iron, white cast iron is another type worth mentioning.
• #3) Ductile Cast Iron.
• #4) Malleable Cast Iron.

Why cast iron has limited engineering application?

Applications are limited, however, to relatively thin-sectioned castings because of the high shrinkage rate and the need for rapid cooling to produce white iron.

What are the main properties of cast iron?

Cast Iron: Properties, Processing and Applications 1 General properties of cast iron. Cast iron is highly favoured for its ability to be easily cast into complex shapes when molten and for its low cost. 2 Types of cast iron and their applications. 3 Production and processing.

What kind of metallurgy does a cast iron have?

Classification and B!asic Metallurgy of Cast Irons THE TERM CAST IRON, like the term steel, identifies a large family of ferrous alloys. Cast irons are multicomponent ferrous alloys, which solidify with a eutectic. They contain major (iron, Solidification carbon, silicon), minor (<0.1 %), and often alloy- ing (>0.1%) elements.

How are specifications used to qualify cast iron?

In order to qualify cast products according to their specifications, a standard practice is to cast a test bar along with the engineered castings. The ASTM tests are then applied to this test bar and the results are used to qualify the entire batch of castings. Specifications are also important when welding cast iron parts together.

How is the corrosion resistance of cast iron improved?

Corrosion resistance of cast iron is improved via the addition of minor elements such as silicon, nickel, chromium, molybdenum and copper. Types of cast iron and their applications Cast iron can be classified into grey cast iron, white cast iron, malleable cast iron and ductile cast iron, depending on its composition.
