I. Basic Concepts of Steel Materials

Hanumānnagar Steel is a metal alloy composed primarily of iron and carbon. It is characterized by its high strength-to-weight ratio, corrosion resistance, and malleability. Steel structures rely on the properties of steel to resist external forces such as wind, earthquakes, and environmental factors.

A. Types of Steel

There are several types of steel, each with unique properties and applications. Some common types include:

1. Ferrous Steel: This is the most commonly used type of steel, consisting mainly of iron and carbon. It has a relatively low yield strength but is highly resistant to corrosion.

2. Alloy Steel: This type of steel contains additional elements such as manganese, nickel, or silicon to enhance its properties. For example, stainless steel is a popular choice for marine applications due to its resistance to corrosion.
