Mild Steel: The Backbone of Modern Construction

In today’s world of construction, manufacturing, automobiles, and other industries, steel is the most common product used in large volumes due to its properties like corrosion resistance, durability, longevity, and robustness. Because of the government’s rapid infrastructure development programme, consumption of steel has significantly increased in the last 10 years. According to a Livemint interview with the Steel Ministry, Steel consumption in FY24 has grown 15% to 64 million tonnes from last year. In the first half of FY23, steel consumption also increased by 11.5% to 55 mt from 49.7 mt in the first half of FY21. The World Steel Association has also said that Indian Steel Demand is expected to grow 6.2% in 2024.

Introduction

The general understanding among most people related to steel is that it's just a blend of iron and carbon. In fact, there are 3500 different grades of steel, depending on its process and the percentage of carbon in it. But here we will not be discussing all 3500 grades of steel because it can be confusing. We will talk about only mild steel, different types of mild steel, and their uses.

Why mild steel?

Mild steel is used on a large scale in various construction and engineering works because it contains a very low amount of carbon, ranging from 0.05% to 0.25%. This low amount of carbon gives mild steel some key advantages:

  • Affordable: Compared to other steel types, mild steel is a budget-friendly option.
  • Strong & Durable: It can handle a good amount of weight and pressure without breaking a sweat.
  • Easy to Work: Cutting, welding, and shaping mild steel is a breeze, making it perfect for various projects.

These qualities make mild steel a versatile material used in countless industries. But there's more to the story! Different levels of carbon content within mild steel create variations, each with its own strengths and uses.

Types of mild steels and their uses

There are different types of mild steel based on their carbon content. Each type of steel has its own properties and specifications that are used for various purposes and applications.Mild steel can be categorised based on low-carbon, medium-carbon, and high-carbon steel according to their uses in diverse sectors:

Low-carbon steel (0.05%–0.30%)

Low-carbon steel is a category of Mild Steel which has a carbon content of 0.05%–0.25%. Low-carbon steel has low strength as compared to high-carbon steel, but due to its low carbon content, this steel is easy to fabricate, weld, cut, and bend into various structures. This Mild Steel is strong enough to be used in Machinery parts, Automobile parts, Roofing solutions, and many more.

Types and Uses of Low-Carbon Steel:

 

                        Types

                        Uses

 Stainless Structural Steel

 Beams, Columns, Channels, pipes, etc

 Galvanized Sheet

 Roofing, Car body parts, Gating, and fencing

 Pipes and Tubes

 Water and Oil Supply, Structure for Ventilation and Heating

 Steel Rods and Bars

 Machinery parts, Nuts, Bolts, appliances, etc

 Steel Sheet Plates

 Bridges and Building frames, Cladding and Protection

 

Medium-Carbon Steel (0.30%–0.60%)

Medium - Carbon steel (M2 steel) has a higher carbon content, comprising a range of 0.30% to 0.60% carbon. These minor increases in carbon significantly affect the metal's characteristics to the next level. More carbon blends result in increased Strength, deformation resistance, High load-bearing capacity, Weldability, and Fabrication to a certain extent as compared to Low-Carbon Steel. Because medium-carbon steel has a higher carbon content, it is suitable for use in various applications such as manufacturing, automobiles, rail industry, gears, and shafts.

Types and Uses of Medium-Carbon Steel:

 

                      Types

                      Uses

 Medium-carbon alloy-steel

 Construction, Automotive, and Manufacturing

Hot-rolled steel

 Gears, Shafts, Axles, and Structural frames

 Steel bars and Plates

 Agricultural Equipment, Automotive Parts, Ship Building, Construction, and Car Wheels

 Steel Angles and Pipes

 Railway tracks, Crank Shafts, Machinery parts, etc

 Cold-drawn steel

 Manufacturing, Aerospace, Building Frame

 

High-carbon steel (0.60%–1.00%)

Low- and Medium-Carbon Mild Steel provides a great extent of Malleability, Weldability, and bendability, but when there is a need for High-strength, Hard, and Durable steel, then High-Carbon Steel stands out as the best performer and top choice for applications such as Manufacturing, Cutting, Rail industry, high-tensile wires, etc.

High-Carbon Mild Steel consists of 0.60% to 1.00% carbon. However, if there is more than 2.00% carbon content in steel along with iron, then it will result in cast-iron metal, which has only limited use and is less durable and brittle.

High carbon mild steel

 

Types and Uses of High-Carbon Steel:

 

                      Types

                      Uses

 Steel Sheets and Plates

 Knives. Cutting Roller, Chainsaw, and Chisels

Mild Steel bars

 Car frame manufacturing, Machine manufacturing, and Building

 Steel Pipes and Tubes

 Construction, Railway Bridges, and Rail sleepers Manufacturing

 Mild Steel Plates

 Train Wheels, heavy-duty Duty Equipment, etc

 Steel Wire

 Cables, Fencing, and Tension wires
