What are the material properties of cast iron?

What are the material 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.
• Elasticity – material’s ability to return to its original dimensions after it has been deformed.

What is material of cast iron pipe?

Cast iron pipe is pipe made predominantly from gray cast iron It was historically used as a pressure pipe for transmission of water, gas and sewage, and as a water drainage pipe during the 17th, 18th, 19th and 20th centuries.

Is Cast Iron Pipe steel?

The main component of cast iron pipe is iron, so it will easily rust and corrode at normal temperature. Therefore, the cast iron pipe usually has a relatively firm anti-corrosion layer, generally asphalt paint or silver paint, and also epoxy paint, so the appearance is The touch is the color and texture of the paint.

What are the 4 types of cast iron pipe?

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.

What are the properties of ductile iron pipe?

Ductile iron has excellent properties of machinability, impact resistance, high wear and tear resistance, high tensile strength, ductility and corrosion resistance. It is strong, both the inner and outer surfaces are smooth, free from lumps, blister and scars. These pipes are free from cracks.

How is iron pipe made?

Cast iron pipe is manufactured by the pit, horizontal or centrifugal method. In the vertical pit method, a mold is made by ramming sand around a pattern and drying the mold in an oven. A core is inserted in the mold and molten iron is poured between the core and the mold.

Is cast iron the same as galvanized steel?

Cast iron is very thick and heavy. Galvanized not nearly as heavy. Galvanized is ‘usually’ used for sink drain,,,like 2″ or 1 1/2″,,,cast is 2-4 ” diameter and usually used in that era of homes for the stack all the way to the roof. BOTH can be troublesome and rust thru.

How can you tell the difference between cast iron and steel pipe?

The specimen can be grinded using an abrasive wheel and looking at the spark pattern and spark color, an experienced person can inform if the material is Cast iron or cast steel. Steel will most often give off bright yellow sparks, whereas iron produces more of red or orange sparks.

Which type of material is iron?

Iron is a brittle, hard substance, classified as a metal in Group 8 on the Periodic Table of the Elements. The most abundant of all metals, its pure form rapidly corrodes from exposure to moist air and high temperatures.

Which of the following material is least corrosion resistant?

Wrought iron is least corrosion resistant, It is usually made by ”puddling process” and besides iron contains a small quantity of slag.

What is the carbon content of cast iron?

Cast iron is an iron alloy containing 2 wt.% – 4 wt.% carbon, 1 wt.% – 3 wt.% silicon and smaller amounts of minor elements. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content.

What’s the difference between cast iron and cast steel?

Cast iron usually refers to gray iron, ductile iron and malleable iron. Which is an iron casting with carbon content higher than 2%. Cast steel usually refers to normal carbon steel and alloy steel. Which is a steel casting with carbon content lower than 2%.

What was the manufacturing method for cast iron pipes?

The Handbook of Cast Iron Pipe (CIPRA, 1967) explains the manufacturing method of cast iron pipes. In the early 1920s, dry sand moulds (CSCE, 1916) were used to produce the pipes. Pipes called McWane pipes, (Babbitt et al., 1962) were produced by casting horizontally.

What is the thermal conductivity of cast iron?

Thermal Conductivity of Carbon Steel vs Cast Iron The thermal conductivity of typical steel is 20 W/ (m.K). The thermal conductivity of gray cast iron – ASTM A48 is 53 W/ (m.K). The thermal conductivity of martensitic white cast iron (ASTM A532 Class 1 Type A) is 15 – 30 W/ (m.K).
