What Is Non Alloy Steel?

Steel is common called carbon steel because of the mixture of carbon atoms with iron atoms. The added elements provide the steel with ductility and strength. During the smelting process, other elements, such as aluminum is added to the steel making it an alloy steel. Non-alloy steel has no elements added to the steel as it is smelted.

Manufacturing

The manufacturing of steel is done by placing ore in a furnace a smelting the ore. The smelting process removes any impurities in the iron ore. Once the first smelting process is performed, the steel still has too much carbon content to become non-alloy steel. The smelting process is performed again and again until the carbon content in the ore falls below 1.5 percent of the total content.

Smelting

The smelting process melts the iron ore. By melting the ore, the extraction of elements and impurities can be accomplished. The manufacturer only wants the iron and a small amount of carbon from the ore to make non-alloy steel. During the smelting process, elements get added to the ore such as cobalt, copper and aluminum, which makes the steel an alloy steel. Non-alloy steel has no other elements added to the iron and carbon during the smelting process.

Tempering

The non-alloy steel must be tempered at a certain temperature because it does not use other elements to make it flexible and durable. Tempering non-alloy steel at a certain temperature make the steel more sensitive to cracking when being welded.

Applications

Non-alloy steel can be used for different applications. Steel bars used to strengthen concrete is a non-alloy steel. Wrought iron is another non-alloy steel because it has little to no carbon within the iron ore. The wrought iron is soft and easily workable into different shapes but has very little strength. Non-alloy steel is often used to make decorative metal gates and fences.

As an important element of steel products, alloy steel pipe can be divided into seamless steel pipe and welded steel pipe according to the manufacturing technique and tube billet shape.

Here you can see the common alloy steel grade that you will come across.

Why the application of alloy steel pipe is wider than others

There are many kinds of materials used for transport in industrial production. Specifically we will have more choices and it is not limited to the use of alloy steel pipe. But even in the face of more choices, many people tend to choose alloy steel pipe. People make their own choices will have their own reasons. This means the alloy steel pipe application has its own advantages. Compared with transmission lines made of other materials, after it meets the basic application requirements, its quantity is lighter. Then in the practical application of alloy steel pipe, it will have more advantages because of this. Besides its physical characteristic advantage, it also has economic advantages. The wide application of alloy steel pipe is with kinds of reasons. So in practical usage, we can exploit the advantages to the full, in this way can we get more profits in these applications of alloy steel pipe.

What requirements should alloy steel pipe application meet

The transportation of kinds of gases or liquids in production needs to rely on alloy steel pipe. This shows that the actual role of alloy steel pipe application is important. High temperature resistant and low temperature resistant is the tolerance of temperature. In the practical application of alloy steel pipe, there will be many materials need to be transported. However their temperatures are not the same. So this can be the basic requirement to alloy steel pipe. It needs more corrosion resistance. Corrosion resistant material is the best material during transporting, because it is corrosion resistant. So it can be used in more occasions. And it is definitely very convenient for users.

The most important and desired changes in alloy steel are

Alloy steels are made by combining carbon steel with one or several alloying elements, such as manganese, silicon, nickel, titanium, copper, chromium and aluminum. These metals are added to produce specific properties that are not found in regular carbon steel. The elements are added in varying proportions (or combinations) making the material take on different aspects such as increased hardness, increased corrosion resistance, increased strength, improved formability (ductility); the weldability can also change.
