What are the main uses of cast iron?

Applications of cast iron

• It is used in making pipes, to carry suitable fluids.
• It is used in making different machines.
• It is used in making automotive parts.
• It is used in making pots pans and utensils.
• It is used in making anchor for ships.

What are the main properties of white cast iron?

White cast iron has a light appearance due to the absence of graphite. It has a high compressive strength and retains good hardness and strength at higher temperatures. The presence of different carbides, depending on the alloy content, makes white cast irons extremely hard and abrasion resistant but very brittle.

What is white cast iron and what is its chief use?

Due to its large masses of carbides, especially when alloyed, white cast iron has an excellent resistance against wear and abrasion. It is commonly used for wear resistant surface. It is used for shot blasting nozzles, rolling mill rolls, crushers, pulverizers and ball mill liners.

What is the difference between white and GREY cast iron?

The difference is that white cast iron features cementite below its surface, whereas gray cast iron features graphite below its surface. The graphite creates the appearance of a gray color, while the cementite creates the appearance of a white color.

What are advantages of cast iron?

Cast Iron Pan Benefits

• Long Life Span. Cast iron cookware has a long life span as well.
• Adds Iron To Your Food.
• Use In The Stove And Oven.
• Easy to Clean.
• Less Expensive.

Which is harder GREY cast iron or white cast iron?

Hardness and Strength White cast iron is harder than grey, to the point that it is quite brittle. Grey iron, by contrast, is softer but stronger. The two types are sometimes combined, allowing a piece to be made with a hard outer coating of white iron and a strong core of grey.

Is white cast iron weldable?

This depends on microstructure and mechanical properties. For example, grey cast iron is inherently brittle and often cannot withstand stresses set up by a cooling weld. White cast iron which is very hard and contains iron carbides, is normally considered to be unweldable. …

What is white iron?

Definition of white iron 1 : iron in thin sheets coated with tin : tinplate. 2 : a hard silvery-white pig iron or cast iron having its carbon content almost entirely in combined form.

Which type of cast iron is the most commonly used?

Grey cast iron
Grey cast iron is characterised by its graphitic microstructure, which causes fractures of the material to have a grey appearance. It is the most commonly used cast iron and the most widely used cast material based on weight.

What is high alloy white cast iron used for?

The high alloy white cast irons are mainly used for abrasion resistant applications and are readily cast into the parts needed in machinery for crushing, grinding, and handling of abrasive materials. The chromium content of high alloy white cast irons increases the corrosion resistance properties of these cast irons.

What are the uses of white iron?

White iron is too brittle for use in many structural components, but with good hardness and abrasion resistance and relatively low cost, it finds use in such applications where wear resistance is desirable, such as on the teeth of excavators, impellers and volutes of slurry pumps, shell liners and lifter bars in ball mills. Malleable cast iron.

Is white cast iron too brittle for structural purposes?

White cast iron is usually considered too brittle to be used for many structural components, but due to its hardness and abrasion resistance properties and low cost, it is an acceptable choice for those applications where wear resistance is desirable. White cast iron has high compressive strength and wear resistance.

What is the difference between white and white cast iron?

White cast iron is formed when, on solidification, carbon in solution is not able to form graphite White cast irons are hard and brittle; White cast iron is formed when, on solidification, carbon in solution is not able to form graphite White cast irons are hard and brittle; they cannot easily be machined.
