Percentage of carbon in steel is _____.a)0.1% to 0.8%b)0.35% to 0.45%...
Steel is an alloy of iron and carbon, along with small amounts of other alloying elements or residual elements as well. The plain iron-carbon alloys (Steel) contain 0.002 - 2.1% by weight carbon. For most of the materials, it varies from 0.1-1.5%.
There are 3 types of plain carbon steel:
(i) Low-carbon steels: Carbon content in the range of < />
(ii) Medium carbon steels: Carbon content in the range of 0.3 – 0.6%.
(iii) High-carbon steels: Carbon content in the range of 0.6 – 1.4%.

The Percentage of Carbon in Steel
Carbon is one of the main elements in steel, and its percentage has a significant impact on the properties of steel. The percentage of carbon in steel is expressed as a percentage of the weight of the steel.
Range of Carbon Percentage in Steel
There are different types of steel with varying carbon percentages, but the most common range of carbon percentage in steel is between 0.1% to 1.5%.
Explanation of Options
Option A: 0.1% to 0.8%
This option is incorrect because it represents a narrow range of carbon percentage in steel. Most steel types have a carbon percentage higher than 0.8%.
Option B: 0.35% to 0.45%
This option is incorrect because it represents a very low carbon percentage in steel. Such low carbon percentage is rare in steel, and it is usually used in special applications.
Option C: 1.8% to 4.2%
This option is incorrect because it represents a high carbon percentage in steel. Such high carbon percentage is used in very few applications, and it makes the steel brittle and difficult to weld.
Option D: 0.1% to 1.5%
This option is correct because it represents the most common range of carbon percentage in steel. Most steel types fall within this range, and it provides a good balance between strength, ductility, and weldability.
Conclusion
The percentage of carbon in steel is an essential factor that affects the properties of steel. The most common range of carbon percentage in steel is between 0.1% to 1.5%.
