Interpretation Introduction

Interpretation:

The benefit of having a eutectic point for ferrous alloys used for casting needs to be explained.

Concept Introduction:

Ferrous Alloys-

The cast iron is brittle in nature because of the presence of iron carbides. Ferrous alloys are also called as cast iron because these are generally manufactured from casting.

The major part of engineering application of ferrous alloys is Steel. Cast iron is mostly used as a structural component. These are used in automobile industry of motor casing, machinery's sliding guides, lathe bed etc.

Classification −Based on the carbon content present:

1. Steel: In steel, the carbon percentage is $\text{2}\text{.14\%}$
2. Cast iron: Carbon percentage is above $\text{2}\text{.14\%}$
