Chapter 12, Problem 12.67P

Interpretation Introduction

Interpretation:

To determine the carbon content of steel and its nature.

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. This increase in the carbon content of steel has a disadvantage too. It increases the brittleness and reduces the weldability 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.
