Chapter 12, Problem 12.64P

Interpretation Introduction

Interpretation:

The carbon content of 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. The hardenability can also be increased by increasing the carbon content. Increasing the carbon content of steel has a disadvantage too. It increases the brittleness and reduces the weld ability as 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 up to $0.4\%$ manganese content.
