what is the stucture of high carbon steel
That is kind of a broad question because high carbon steel can cover a broad range and you did not mention the condition. But I will try to keep it simple. If it is in a wrought condition, it would likely be pearlite plus carbides along the grain boundaries., The atomic structure would be body centered cubic. Sometimes high carbon steel is spherodized annealed and that would be ferrite with lots of round carbides. The atomic structure would be body centered cubic. If it is quench and tempered, it would be martensite and would probably have noticeable carbides if the carbon content was high enough. The atomic structure would be body centered tetragonal
I dont know percentages just that it is basic steel with added carbon it is used for tooling and other reasons that need a steel that can be hardened ~~
