These metal strips are highly versatile and can be used for a wide range of applications. From construction to manufacturing, these flat bars are perfect for anyone looking for a sturdy and reliable material to work with. Plus, they’re incredibly popular due to their strength, durability, and ease of use. So whether you’re building a structure or crafting a product, consider using a S275 grade mild steel flat bar from Speciality Metals to ensure your project is safe and sturdy.
Our flat mild steel bar is available in S275 grade. Engineers and contractors use flat bar extensively in the manufacture of support braces, latches, mechanical parts, industrial tools, etc., as well as for many DIY projects.
We also offer this 100mm wide steel strip in a far denser 20mm thickness. When flat bar is this thick it is more like a billet.
For those in need of sturdy and reliable steel material, the mild steel flat bar offers a versatile solution. As a popular choice in the construction and manufacturing industries, this steel strip provides a solid foundation for various structures and machinery. With its uniform width and thickness, the mild steel flat bar offers consistent strength and durability for a wide range of applications.
As a result of its good to excellent formability, mild steel flat bar can easily be joined by welding processes or by means of fixings such as rivets, bolts and screws.
Flat mild steel bars are available in various lengths from Speciality Metals, a UK-based supplier of industrial materials. These solid metal plates measure 100mm wide and 3mm thick, making them both durable and versatile. Flat mild steel bars offer excellent welding, forming, bending and machining capabilities, making them ideal for a variety of applications. They are also cost-effective and recyclable, which increases their appeal. In addition to their malleability, these bars can also be easily customised to meet specific requirements. If you’re looking to build a sturdy frame or provide support for an existing structure, Speciality Metals’ flat mild steel bars are what you need.

Improving the tensile strength of a flat mild steel bar involves a combination of different methods:
Heat Treatment: This is one of the most common ways to increase the tensile strength of steel. There are different heat treatment processes like quenching and tempering that can be used to increase the tensile strength of mild steel. Quenching involves heating the steel to a certain temperature and then cooling it rapidly in water or oil. This process hardens the steel and increases its tensile strength. Tempering is done after quenching and involves heating the steel again to a lower temperature and then cooling it slowly. This process helps to remove the brittleness caused by quenching and makes the steel tougher.
Cold Working: This process involves deforming the steel at room temperature. Methods of cold working include rolling, drawing and bending. Cold working introduces dislocations in the steel which hinders the movement of dislocations and thereby increases the tensile strength. However, excessive cold working can make the steel brittle. So, it should be done carefully.
Adding Alloying Elements: Adding elements like carbon, manganese, chromium, nickel, etc., can increase the tensile strength of mild steel. These elements form carbides or other phases in the steel that prevent dislocation movement and thereby increase the strength.
Controlling the Grain Size: Smaller grain sizes in the steel result in higher tensile strength. This can be achieved by carefully controlling the cooling rate during the heat treatment process.
Surface Treatment: Surface treatments like carburising or nitriding can also increase the tensile strength of mild steel. Carburising involves adding carbon to the surface of the steel and then quenching it. Nitriding involves diffusing nitrogen into the surface of the steel.
Work Hardening: This involves deforming the steel plastically which introduces more and more dislocations in the steel which hinders the movement of dislocations and thereby increases the tensile strength.
Mild steel, also known as low carbon steel, is not recommended for use in acidic environments. Acidic environments are highly corrosive, and mild steel does not have the corrosion resistance properties needed to withstand such conditions. In acidic environments, mild steel will corrode rapidly, leading to a loss of material and structural integrity. This can lead to failure of the component or structure made from mild steel. Stainless steel or other corrosion-resistant materials are recommended for use in acidic environments. If you must use mild steel, it should be coated with a corrosion-resistant coating or paint. However, even with a protective coating, mild steel is not the ideal material for acidic environments and other materials should be considered if possible.
Mild steel flat bars have a moderate resistance to abrasion, which means they can be susceptible to wear and tear in applications that involve a lot of friction or abrasive contact. Mild steel is made of low carbon steel, which means it is softer and more ductile compared to high carbon steels or alloy steels. This makes it less resistant to abrasive wear. While it can be used in applications with mild abrasion, it is not recommended for heavy abrasive applications. For applications with high abrasion, materials with higher abrasion resistance like high carbon steel, alloy steel or abrasion-resistant (AR) steel are recommended. If mild steel flat bars must be used in abrasive applications, it is recommended to apply surface treatments like hardfacing or applying wear-resistant coatings to improve their abrasion resistance.
