What carbon range does low carbon steel have?

1. 0.05-0.3% carbon

2. 0.3-0.45% carbon

3. 0.45-0.6% carbon

4. 0.6-0.75% carbon

The correct answer is: 0.05-0.3% carbon

Low carbon steel typically refers to steel with a carbon content of 0.05-0.3%. This is considered low compared to other types of steel, such as high carbon steel which has a higher carbon content. Options B, C, and D all have higher carbon ranges, so they would not fall under the category of low carbon steel. It is important to note that these carbon ranges may vary slightly depending on the specific industry and standards being used.
