What Grade Steel is Majorly Used in Fabrication


Steel is an alloy of iron and carbon, and it is one of the most widely used materials in the construction industry due to its strength, durability, and versatility. The grade of steel used in fabrication depends on the specific requirements of the project, including the structural design, load-bearing capacity, and environmental conditions.


In general, there are several grades of steel used in fabrication, ranging from low to high strength. The most commonly used grades of steel in fabrication include:


Mild Steel (Grade 250)

Mild steel is a low carbon steel with a maximum carbon content of 0.25%. It is the most commonly used steel in fabrication due to its affordability, versatility, and ease of welding. Mild steel is ideal for projects that do not require high strength or resistance to corrosion, such as fencing, gates, and small structures.


High Tensile Steel (Grade 350)

High tensile steel is a type of carbon steel with a higher yield strength than mild steel. It has a carbon content of up to 0.55% and is alloyed with other metals, such as manganese, chromium, and vanadium, to improve its strength and durability. High tensile steel is commonly used in structural and load-bearing applications, such as bridges, buildings, and heavy machinery.


Structural Steel (Grade 250 or Grade 350)

Structural steel is a type of high tensile steel that is specifically designed for use in construction and engineering applications. It has a high yield strength and is commonly used in the construction of buildings, bridges, and other large structures. Structural steel can be either Grade 250 or Grade 350, depending on the specific requirements of the project.


Stainless Steel (Grade 304 or Grade 316)

Stainless steel is a type of steel alloy that contains at least 10.5% chromium, which gives it its unique properties of corrosion resistance and strength. It is commonly used in applications where hygiene and sanitation are important, such as in the food and beverage industry, as well as in medical equipment and laboratory settings.


Conclusion

The grade of steel used in fabrication depends on the specific requirements of the project, including the structural design, load-bearing capacity, and environmental conditions. Mild steel is the most commonly used steel in fabrication, while high tensile steel and structural steel are used in load-bearing applications. Stainless steel is used in applications where hygiene and corrosion resistance are important.
