Q1: What Is Mild Steel Beam?

Mild Steel Beam is a structural element designed primarily resists load and manufactured from mild steel which is a composition of iron and low carbon percentage (0.05 – 0.25%). The mild steel beam is the commercial term of “low-carbon steel beam” or “plain carbon steel beam”.

Mild steel beam being made from material properties that contain a low carbon content, this made it a very strong, ductile, weldable, malleable and easy to form than any other type of steel.

A mild steel beam is available in several shapes, profiles, grades and standards. Mild steel beam, in particular, is used almost anywhere in the world steel industry, its economic price and distinctive characteristics made it the best choice for construction and civil engineering structural applications, especially, where large quantities of steel are required.

Q2: What Are The Applications Of Mild Steel Beam?

In today’s steel market, mild steel beam is becoming increasingly in-demand for almost all construction, engineering and mechanical industry, because of its relatively low price, unparalleled weldability, machinability, strength, ductility, and versatility.

Q3: What Are The Production Processes Of Mild Steel Beam?

Mild steel beam production processes, techniques and materials are similar to other types of a carbon steel beam.

Materials Used

Mild steel beams are made mainly from Iron (98.81 – 99.26 %), Carbon (up to 0.25%), Manganese, Sulfur, and Phosphorous.

A mild steel beam is primarily manufactured using many steel grades with carbon content within the limits of 0.25%, while other properties are added to improve tensile strength and corrosion resistance.

Production Processes

Production of mild steel beam is similar to other carbon steels. The common manufacturing operation passes through the following stages:

Primary Forming

Basic Oxygen Steel Making (BOS, BOP, BOF, or OSM) or oxygen converter process, is the primary method of steelmaking in which carbon-rich molten pig iron is made into steel. In the BOS process oxygen is blown through molten iron, while scrap steel is added to the converter.

This lowers the percentage of the carbon content of the alloy elements and changes it into low-carbon steel to a maximum of 1.5% and results in impressive quality steel.

Carburizing Mild Steel Beam Process

Because of its low carbon and other alloy content, the process of quenching and tempering mild steel beam does not form a martensite structure. This results in a low tensile strength surface and hardness (yield and tensile), but it can be increased initially through carburizing. Whereas heat treatment operation’s role is to diffuse carbon into the low-carbon mild steel beam surface to increase hardness using a modern computerized gas carburizing furnace.

The following are the main steps to carburizing mild steel beams:

• Mild steel beam after being heated to austenitization temperature, it is then exposed to carbrurising atmosphere.

• The mild steel is kept under constant temperatures for minutes or up to a number of hours till getting the desired carbon level and depth.

• After the diffusion process is being completed, the mild steel is quenched and dumped quickly in oil, polymer, or water.

• Carburising case depth ranges from microns to several millimeters (0.010″ to 0.200″). Wear-resistant layer (case) depth is determined by the required application and material specifications.

Secondary Forming

Secondary forming involves transforming mild steel into the final required beam shape, size and performance.

• Once mild steel is melted, the whole content is moved to another furnace to burn out any impurities.

• Adjustments are made to the mild steel’s chemical composition, following that, the mild steel is poured into a mold to get shaped and solidify; this is called the casting process, which enhances the mild steel beam performance.

• Hot rolling or cold rolling manufacturing methods are applied from mild steel to the desired beam size and shape.

• Various finishing techniques can be carried out to provide a surface free from any casting defects.

• Finishing processes are applied to a mild steel beam in order to offer the final required characteristics, this may include the following process:

Machining.

Coating.

Surface preparation.

Cutting mild steel beam into the desired shapes.

Q4: What Is The Melting Point Of Mild Steel Beam?

Mild steel beam has a high melting temperature point of 1350^oC – 1530^oC (2462^oF-2786^oF).

In other words, it has a density of .248 pounds per cubic inch, it melts at 2,570 degrees Fahrenheit and has a specific heat of around .122 British Thermal Units (BTU) per pound, per cubic inch.

High melting temperature makes mild steel beam versatile, ductile and therefore suitable for a huge range of structural steel applications.

Q5: What Are The Properties Of Mild Steel Beam?

Mild steel beam is a ferrous metal, it’s a combination of iron (98.81 – 99.26 %), low carbon (0.05–0.25%) and other alloys elements:

Manganese          : 0.60 – 1.50 %.

Sulfur                     : ≤ 0.050 %.

Phosphorous               : ≤ 0.040 %.

This composition keeps mild steel beam prices relatively low while containing properties that make it appropriate for all applications.

Mild steel beam is made of low carbon amount, it is more malleable and easier to work than higher carbon steels.

1018 Mild Steel Beam is the commonly used mild steel beam grade, it contains:

• Iron : 98.81 – 99.26%.

• Carbon : 0.18%.

• Manganese: approx.6 percent to .9 percent.

• Phosphorus: up to .04 percent.

• Sulfur: up to .05 percent.

• Added alloying properties percentage may vary according to the desired mechanical properties, corrosion resistance, strength and weight.
