What is FG cast iron?

Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. It is the most common cast iron and the most widely used cast material based on weight.

What is FG in steel?

Standard Flake Iron (FG) High Strength Flake Iron (HS)

What are the 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.

What do you mean by FG 300?

The material for the pallet is FG 300. It is the grade of cast iron with ultimate tensile strength of 300 MPa and rest of mechanical properties are listed below. SG iron has high plasticity and good toughness, the tensile strength of ductile iron is 414 Mpa and the yield.

Why is pig iron called pig iron?

The term “pig iron” dates back to the time when hot metal was cast into ingots before being charged to the steel plant. The moulds were laid out in sand beds such that they could be fed from a common runner. The group of moulds resembled a litter of sucking pigs, the ingots being called “pigs” and the runner the “sow.”

What is the full form of FG?

What 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. It is made by reducing iron ore in a blast furnace. Most cast iron is either so-called gray iron or white iron, the colours shown by fracture.

Which type of casting iron is the strongest?

Gray iron is also easier to machine than other cast irons, and its wear resistance properties make it one of the highest volume cast iron products.

Why is cast iron not weldable?

It is possible to weld cast iron, although it can be problematic due to the high carbon content. The welding process causes this carbon to migrate into the weld metal and/or the heat affected zone, leading to elevated brittleness/hardness. This, in turn, can lead to post weld cracking.

What is FG200 material?

Cast iron is an alloy of iron and carbon. I.e., FG200 that means grey cast iron with ultimate tensile strength 200 N/mm2.
