Three types of steel

As manufacturing processes evolve and become more complex, the choice of steel buyers has expanded to suit many unique needs across a wide range of industries.steel coil manufacturers

But not all types of steel are equal. Professionals in the pipeline industry can check the types of steel available today and understand why some steel pipes can make good steel pipes and other steels cannot be better steel.

1.Alloy steel

Alloy steels are like they sound: steels with a specific amount of alloying elements. In general, alloying elements make steel stronger and more resistant to impact or stress. Although the most common alloying elements include nickel, chromium, molybdenum, manganese, silicon and copper, many other elements are also used in the production of steel.

Numerous combinations of alloys and concentrations are used in the industry, each of which is designed to achieve a specific quality.

High-alloy steels are favored in the pipeline industry and are suitable for use in extreme conditions, whether in hot or cold conditions or in rough use. This is because the combination of chemistry and proper heat treatment produces a strong but ductile pipe that can be struck. The oil and gas and power generation industries often prefer alloy pipes due to their toughness.

The alloying elements also give the steel pipe a higher corrosion resistance. This makes it the first choice for chemical companies.

2.Carbon steel

Steel is produced when carbon is added to iron, and the iron itself is relatively weak. In modern industry, carbon is the most prominent additive in iron-based materials, but various alloying elements are common.

In fact, alloying elements are common even in pipeline products that are still considered carbon steel.

According to the American Iron and Steel Institute (AISI), when its core composition contains no more than 1.65% manganese, 0.60% silicon and 0.60% copper and when no other minimum content is specified, the iron-containing material is designated as carbon steel. alloy element.

Carbon steel pipes are widely used in many industries due to their strength and ease of processing. Carbon steel pipes are relatively inexpensive because they contain relatively few alloying elements and have a low concentration.

However, it is not suitable for extreme temperature or high pressure service because of the lack of alloying elements which reduce its resistance to accompanying stresses.

3.stainless steel

This word is a bit of a misnomer. There is no combination of iron and alloying elements that makes stainless steel a reality. In contrast, stainless steel refers to products made from it that do not rust.

Alloys in stainless steel may include chromium, manganese, silicon, nickel and molybdenum. Together, these alloys interact with water and oxygen in the air to quickly form a thin, strong film on the steel to prevent further corrosion.welded pipe manufacturers

Of course, stainless steel tubes are used in any industry where corrosion protection is required. Although the stainless steel tube is basically another name for the alloy tube, it is not suitable for extreme service unless it is prioritized to increase strength and impact resistance.

Due to its aesthetic appeal, stainless steel is often chosen if the pipe must be seen in a public or professional environment.
