Industrial Carbon Steel Square Bars
Industrial carbon steel square bars are a versatile metal that can be used in a variety of construction and manufacturing projects. They’re also a great choice for ornamental iron work.
Square bar carbon steel has high workability, making it easy to weld, form, cut, and machine. It retains tight dimensional tolerances and has a smooth surface finish.
Grade A36
The A36 carbon steel grade is a common structural grade and can be found in a variety of applications. It has a high strength to weight ratio and is easy to machine, build, and weld. It also has good ductility and is highly formable.
A36 is a low-carbon steel that contains 0.25% to 0.3% carbon. It also has a significant amount of manganese, which gives it an overall well-rounded set of properties. While it has lower tensile strength than higher-carbon steels, its strength to weight ratio is excellent.
It is made by melting iron ore and coal in a furnace and burning away impurities. The molten metal is then mixed with alloying elements to create the desired chemical composition and then solidified into ingots. The ingots are then hot rolled. This process stretches the ingots to their final dimensions and increases their hardness.
The A36 steel grade is often compared with 1018 carbon steel. These two grades are similar, but 1018 has a higher machinability rating than A36. This is because A36 is usually hot rolled, while 1018 is cold rolled. Cold rolling is a less labor intensive process and can produce a better surface finish. Both grades are very versatile and can be used in many applications, but 1018 is generally preferred if machinability is a priority.
Grade 1020
AISI 1020 is one of the most commonly used plain Industrial carbon steel square bars carbon steels because it has good machinability and weldability. This grade is similar to the 1018 type of steel, but it has a higher percentage of carbon in it: 20 percent versus 18%. Like many other plain carbon steels, it can be hardened through heat treatments such as carburizing and carbonitriding. The recommended preheat and interpass temperature for surface hardening is 760-790 degC (1400-1450 degF).
Its flexibility makes it useful in a wide variety of applications, including heavy trucks, automotive, agricultural, and industrial machinery. It can be made into angle iron, channel iron, I-beams, H-beams, and flat bars. It’s also commonly used to manufacture camshafts, axles, gudgeon pins, and ratchets.
Because of its good machinability and weldability, this grade is an ideal choice for fabricating steel-floor and roof joists, walkways, railings, and concrete forms. It’s also perfect for forming simple structural parts where high-quality surface conditions aren’t critical. In addition, merchant carbon steel bars are ideal for use in applications where reducing weight will result in cost savings or when environmental concerns are an issue.
Black Steel
The versatility of metal square bars makes them a popular carbon steel round bar choice for a wide variety of applications. They are durable, dependable, and can be used in permanent or semi-permanent constructions as well as fabrication work. They are also a great option for projects where strength is crucial but precision is not needed. In addition, these sturdy bars can withstand heavy loads and climatic conditions such as earthquakes and cyclones.
While both carbon steel and stainless steel can be used for industrial purposes, there are some key differences between them that influence the final result. Stainless steel can be better shaped using heat treatment, which can significantly enhance its mechanical properties. However, this can come at the expense of corrosion resistance. In comparison, carbon steel is less expensive and offers more flexibility.
Choosing the right material for your project depends on your requirements and budget. Stainless steel is more costly than carbon, but it offers superior durability and corrosion resistance. However, if you’re looking for a more cost-effective solution, black steel is an excellent choice for projects that prioritize strength and reliability.

Bright Steel
Unlike black steel, bright carbon square bars are drawn to more exacting tolerances. The final product is often polished, allowing it to withstand higher levels of stress. It also possesses sharp, perpendicular and parallel sides and is sometimes bead blasted to make it more “bright.” This type of steel bar is ideal for use in manufacturing/construction projects that require a high level of precision and accuracy.
These industrial carbon steel square bars are made from a wide variety of alloys and graded according to their strength, durability, corrosion resistance and more. As a result, they can be used in various engineering applications including frame work, support beams and axles. The material is also able to resist cracking, making it the perfect choice for demanding environments.
In order to produce bright steel, raw/input materials are annealed at high temperatures which eliminates any defects and decarburized layer. This allows the metal to be rolled into various shapes like rounds, flats and squares. After this, the bar is subjected to further fine-finishing processes such as turning and grinding which remove surface imperfections and creates a better finish quality. This produces a bar with a greater tolerance, concentricity, straightness and superior surface integrity compared to black steel. Moreover, these products are also more cost-effective than black bars due to the lower cost of production and finishing.
