Introduction

FG 200 and FG 260 are two types of cast iron that are commonly used in various industries. Both materials have their own unique attributes that make them suitable for different applications. In this article, we will compare the attributes of FG 200 and FG 260 to help you understand the differences between the two.

Chemical Composition

FG 200 and FG 260 have different chemical compositions that affect their mechanical properties. FG 200 has a higher carbon content compared to FG 260, which makes it more brittle but also more resistant to wear and tear. On the other hand, FG 260 has a lower carbon content, which makes it less brittle but also less resistant to wear and tear.

Strength and Hardness

When it comes to strength and hardness, FG 260 is generally considered to be stronger and harder than FG 200. This is due to the lower carbon content in FG 260, which allows for a more uniform distribution of graphite in the material. As a result, FG 260 is able to withstand higher loads and pressures compared to FG 200.

Impact Resistance

FG 200 is known for its high impact resistance, which makes it suitable for applications where the material is subjected to sudden shocks or impacts. On the other hand, FG 260 has lower impact resistance compared to FG 200, which means it may not be as suitable for applications where impact resistance is a critical factor.

Machinability

When it comes to machinability, FG 200 is generally easier to machine compared to FG 260. This is because the higher carbon content in FG 200 makes it more brittle, which allows for easier cutting and shaping of the material. On the other hand, FG 260 may be more difficult to machine due to its lower carbon content and higher strength.

Corrosion Resistance

FG 260 is known for its better corrosion resistance compared to FG 200. This is due to the lower carbon content in FG 260, which makes it less prone to rust and corrosion. On the other hand, FG 200 may be more susceptible to corrosion, especially in harsh environments or when exposed to corrosive substances.

Applications

FG 200 and FG 260 are both used in a variety of applications across different industries. FG 200 is commonly used in applications where high wear resistance and impact resistance are required, such as in the manufacturing of gears, bushings, and machine parts. On the other hand, FG 260 is often used in applications where high strength and hardness are needed, such as in the manufacturing of automotive parts, valves, and pumps.

Conclusion

In conclusion, FG 200 and FG 260 have their own unique attributes that make them suitable for different applications. FG 200 is known for its high wear resistance and impact resistance, while FG 260 is valued for its high strength and hardness. When choosing between FG 200 and FG 260, it is important to consider the specific requirements of your application to determine which material is the best fit for your needs.
