Chapter 12, Problem 12.65P

Interpretation Introduction

Interpretation:

The carbon content of the steel needs to be calculated. Whether the seel is hypoeutectoid or hypereutectoid needs to be determined.

Concept Introduction:

Usually carbon is the most important commercial steel alloy. By increasing the carbon content, we can increase the hardness and strength. Hardenability can also be increased by increasing the carbon content. Increasing the carbon content of steel has a disadvantage too. It increases brittleness and reduces the weldability since it has the tendency to form martensite. The type of carbon steel is mild steel which contains approximately $0.05\%$ to $0.25\%$ carbon with certain manganese content as well.
