Percentage of carbon in steel ranges from

Answer» <html><body><p> 0.1 to 1.5</p><br/><br/><p>Steel is an alloy made by combining iron and other elements, the most common of these being carbon. When carbon is used, its content in the steel is between 0.2% and 2.1% by weight, depending on the grade. Other <a href="https://interviewquestions.tuteehub.com/tag/alloying-857985" style="font-weight:bold;" target="_blank" title="Click to know more about ALLOYING">ALLOYING</a> elements sometimes used are manganese, chromium, vanadium and tungsten. Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another.

Steel with increased carbon content can be made harder and stronger than iron, but such steel is <a href="https://interviewquestions.tuteehub.com/tag/also-373387" style="font-weight:bold;" target="_blank" title="Click to know more about ALSO">ALSO</a> less ductile than iron.
