Carbon Steel 

Carbon steel compared to other raw material steels has a higher carbon content, including iron and manganese. Carbon steel as an electrical enclosure material is considered to be one of the widely and known used material steel because compared to other steels available, it has many functions and advantages that includes in its efficiency. Carbon steel is malleable, therefore it can be melted and can be turned into different specific shapes. 

There are generally four types of carbon steel according to these categories: low or mild steel, medium steel, high steel, and ultra high steel. 

Low steel contains lower content of carbon among all other types of carbon steel. This type of carbon steel is easier to form a shape and this is the most affordable compared to other types of metals. It is commonly used in manufacturing equipment for construction purposes. Despite the advantages, it has low strength and durability because of the lower carbon content. 

Medium steel is another type of carbon steel which is resistant to longer use or wear and tear. Compared to low steel, this is more durable and stronger. Medium steel is commonly used in producing large metal structures and automotive accessories such as axles, shafts, couplings and other materials applicable to this industry. 

High steel is one of the strongest carbon steel ever known because it has a high steel variety. It is generally used in producing high strength springs and wires. 

Ultra high steel is a carbon steel type which is very formal, but strong recommended to use in manufacturing knives and axles. These types of carbon steel, metals are used in the production of various types of industrial tools and machines. Ultra high steel carbons are used extensively in producing different cutting tools, drill bits, and knives because these types of tools require strong but very flexible material.

General Information about Stainless Steel NEMA 4X for Corrosion Resistance

Stainless steel is the generic term used to call a number of steels used in making metals used for manufacturing different sorts of products, especially electrical enclosures. Because of the mixture of metals, this produces a raw material that provides protection from oxidation resulting to corrosion. Generally, all stainless steel is composed of a minimum percentage of 10.5% chromium. This element is widely known for prevention of corrosion – but the other elements, especially nickel and molybdenum are also added to stainless steel to improve corrosion resistance. A good advantage determines the success of any metal. The chromium component in stainless steel is proven to react best with oxygen, and this element provides a film of chromium oxide on the molecular level -usually on the surface.

Nemaco Technology offers the following types of NEMA 4X enclosures:

Carbon Steel used for Enclosures

Most forms of carbon steel are malleable, therefore it can be easily formed, shaped, cut and welded. Typically, cold rolled carbon steel (CRS) are common grades of steel of low or medium carbon content in the steel.

CRS in flat sheet format is commonly used as an electrical enclosure and cabinet material since it has structural strength and rigidity when formed(folded) into enclosure sides and other related enclosure parts. Of course, CRScost less than stainless steel and it has many functions and advantages but it does not have the corrosion resistance properties of stainless steel.

Powder coated CRS is ideal for many NEMA 3R Enclosures products generally due to the materials lower cost, overall strength and weldability.

Custom Metal Enclosures

Different Types of Custom Metal Enclosures for Electrical Equipment

Any company who needs custom electrical enclosures for their equipment can be provided by any enclosure manufacturing company. They just have to be specific to the design that they want to achieve. This also includes the type of steel material they would like to have, such as – aluminum, stainless and carbon steel. Lead times may also vary so a good communication about what is needed to be achieved is important.

Also, there is an option for an enclosure to be customized – via silkscreen or engraving. In addition to this, a clear understanding of the NEMA or IP rating needed for the specific enclosure will be helpful in communicating to a certain manufacturing company of the enclosures needed to be designed.

Enclosure types

There are several types of customization a company can choose from wall mount, free-standing, floor mount, JIC and through. It is important to note that the size of these enclosures is not limited, they can be built according to the needed size for the electrical equipment. One of the most common ones is the free-standing portable enclosures.
