Mild steel fittings are primarily made of iron, with a carbon content usually between 0.15% and 0.25%, which gives them excellent ductility and weldability. The addition of elements like manganese, silicon, and small amounts of phosphorus and sulfur boosts their strength and machinability. Typically, these fittings have tensile strengths ranging from 400 to 550 MPa and yield strengths around 250 MPa. Mild steel also boasts high elongation and impact resistance, making it ideal for a variety of mechanical and structural applications. The low carbon content helps reduce brittleness and allows for easy forming, cutting, and welding, ensuring they can adapt to a wide range of engineering tasks.

Mild Steel Fittings are made from low carbon steel that contains 0.05–0.25% carbon, along with balanced amounts of manganese, silicon, and trace elements. This blend gives them a tensile strength of 400–550 MPa and a yield strength of around 250 MPa, along with impressive ductility and formability. Mild steel is easy to machine, weld, and shape into various forms and sizes. While it has moderate corrosion resistance, protective coatings like galvanizing, painting, or epoxy are often used. These characteristics make Mild Steel Fittings a cost-effective option for applications that don’t require extreme corrosion resistance.
Mild steel fittings are extensively used across many industries because of their strength, versatility, and cost-effectiveness. They play a crucial role in plumbing and piping systems, connecting sections in water, oil, and gas transportation networks. In construction, they are vital for frameworks, support structures, and reinforcements. The automotive and machinery sectors rely on them for the manufacturing and maintenance of mechanical systems. Additionally, mild steel fittings find their place in HVAC systems, fire protection setups, and various fabrication projects. Their ease of machining and compatibility with welding make them perfect for custom fabrication and repair work, catering to both heavy-duty industrial needs and smaller projects.
