Steel Rate In Pakistan

Overview

Steel is the most used material in Pakistan. It is mostly used in the construction department. In these circumstances, the rate of steel is increasing day by day.

So in this article, I will discuss steel and the prices of steel. It will help you to know about everything regarding steel. I will discuss steel in detail.

What is Steel?

Steel is an alloy made of iron with a few percentages of carbon to increase strength and resistance. Iron is the main metal of steel.

Steel is extensively used for buildings, cars, trains, machinery, electrical appliances, and weapons. Steel is a low-cost metal.

The popularity of steel is due to its low cost. The raw materials used for steel are iron ore and scrap. They are used because of their mechanical properties.

Properties of steel

The base metal iron:

The main metal of steel is iron. Iron is present in its pure form, softer than copper, but iron is required in solid form. The solid form of iron is polycrystalline.

It is made up of many crystals that are connected with their boundaries. Steel is the allotropy of iron which is present in two in two crystalline forms one is body-centered cubic, and the other is face-centered cubic.

Effect of carbon:

In the proper procedure of making the steel and increasing the small amount of carbon is added. In steel, carbon is found in two forms. It is present in solid solutions in austenite and ferrite, and the other is carbide.

Effects of heat treatment:

Steel conversion is done by adding carbon—more changes are done by heat treating. The rate of cooling accelerated through the transformation of austenite to the ferrite transformation point.

Effects of alloying:

Another way to make changes in steel is by adding about 20 elements used for alloying steel, which affect the holding time, cooling rates, and temperatures. We get high-strength steel with good weldability due to the addition of alloy elements. This can’t be done by adding only carbon. Other alloy elements are also needed.

Testing of properties:

Many steel tests are used in many industries in Pakistan to check steel properties, like wear tests for rails, drawability tests for sheets, and bending tests for wires. Steel was also checked in laboratories.

In laboratories, thermal elongation and electromagnetic properties are also checked. Spectrometers are also used to check the chemical composition. Ultrasonic and Magnaflux tests are non-destructive tests that check internal and external flaws like cracks and laminations.

Types of steel:

Here we will discuss four types of steel

  • Carbon steel
  • Stainless steel
  • Alloy steel
  • Tool steel

Carbon steel

Carbon is the main element of steel. Although the carbon is added in a very small amount, the nature of carbon makes the steel stronger and more durable. Further, three types of carbon steel are Low carbon, Medium carbon, and high carbon.

Low carbon use in bolts, wires, and pipes. Medium carbon is used in gears and railway tracks. High carbon is used in sharp cutting tools and brick nails.

Stainless steel

Stainless steel is mostly used in medical equipment and appliances. Chromium alloy is added to prevent the metal from rusting. It is oxidation resistant. The chromium content is added about 10.5% up to 30% in many appliances. Stainless steel is mostly used and valued. It has further subcategories used for different purposes Martensitic alloy, Ferritic Alloy, Austenitic alloy, and Duplex alloy.

Alloy steel

Iron is combined with many other elements, and all the elements show their unique properties to the final product. Types of alloy steel are aluminum, copper, manganese, molybdenum, silicon, and vanadium.

Tool steel

Tool steel is used to manufacture the machinery. It is extremely hard and heats resistive. In manufacturing tool steel, different tools are required, such as Air- hardening, Water- hardening, oil-hardening, high speed, Hot-working, and shock resisting.

Conclusion

In this article, I discussed steel in detail. What is steel? Types of steel different properties of steel in detail and different steel rates in Pakistan Testing steel in different industries.

In Pakistan, many famous steel companies are giving the best product at different rates with the best quality. The use of steel is increasing daily, and the rate of steel is also increasing.

Do you know?. Pakistan produces approximately six million metric tons of steel per year.
