Over 1.5 billion tons of steel are produced yearly to make all kinds of products, from household items to structural beams for skyscrapers. The most common type of steel is low-carbon steel, also known as mild steel. Mild steel is used in virtually every industry, particularly in the construction and automotive industries.

Because it is inexpensive, versatile, and readily available, mild steel is the most common metal used by home metalworkers, makers, and DIYers. Its uses are endless—its mechanical properties suit almost any application, and it’s more affordable than high-carbon steels, especially in the form of reusable metal remnants.

In this post, we’ll go over some mechanical and physical properties of mild steel and how to get the best prices by buying verified remnants instead of new alloy steel or other carbon steels.

What Is Mild Steel or Low Carbon Steel?

Mild steel is an industry term for low-carbon steel, which has a carbon content of approximately 0.05 to 0.3% by weight. For comparison, medium-carbon steel has a carbon content ranging from 0.3% to 0.6%, while high-carbon steel can contain up to 2.5% more carbon content by weight than low-carbon steel.

The low carbon content of mild steel gives it specific mechanical properties that make it ideal for certain types of projects. Some of the most notable properties of mild steel include:

High ductility: Mild steel is very ductile due to its low carbon content and the absence of other alloying elements. This means that mild steel can be readily formed compared to other grades of steel without losing its toughness.
High machinability: Mild steel is relatively soft because of its high ductility. This means that it is more easily machined than more rigid carbon steels.
High weldability: The ductility also makes mild steel suitable for welding, both to itself and other types of steel. Low-carbon steel is easier to weld than other grades of mild steel.
Low cost: The chemical composition and ease of manufacture make mild steel a very inexpensive material.

However, mild steel also has some disadvantages. Unlike higher carbon steels, heat treatment processes cannot significantly improve the physical properties of a mild steel grade. It’s also vulnerable to rusting when exposed to moisture, which makes it susceptible to further corrosion.

In these conditions, stainless steel, known for its superior corrosion resistance, is probably a better option but is also more expensive. Mild steel is a great choice when the application requires the tensile strength and durability of steel but not the corrosion resistance of stainless steel.

Low-carbon steel is particularly advantageous for projects where cost efficiency and ease of manufacturing are critical. Its chemical properties make it an in-demand material for various applications.

Mild Steel Uses

Mild steel is the most common type of carbon steel and can be found in many kinds of products and industries. The following are some of the uses of mild steels:

Building frames: Mild steel beams are commonly used in construction projects for building frames because of their high tensile strength.
Manufacturing equipment: Products made of mild steel are commonly used in industrial equipment, such as platens, welding tables, fixtures, and jigs because they are inexpensive, strong, and durable.
Machinery parts: Mild steel makes excellent components for machine elements like gears, bearings, and springs that don’t need the corrosion resistance of stainless steel.
Pipes: Due to its excellent weldability, this metal is used to create mild steel pipes that are strong enough to contain high-pressure fluids. Steel pipes made from mild steel are widely used in various industries.
Cookware and cutlery: Low-carbon steel knives retain sharp edges for a long time. It can also be used to make cookware with non-stick properties that are more durable than cast iron and have a higher temperature limit than non-stick coatings.

Maximizing Value with Mild Steel Production and Fabrication

Even newly milled mild steel is affordable, but there are ways to get even lower prices. Verified mild steel remnants, often byproducts of steel fabrication processes in various industries, are available at prices much lower than steel sourced directly from a mill. Hot rolling is one process used in these steel fabrication methods, where the molten iron is shaped and solidified into usable remnants during metalworks operations.

Because mild steel is used in large quantities by manufacturers in the San Francisco Bay Area, these manufacturers have large volumes of usable material left over after manufacturing.

Local metal recyclers specializing in recycling and selling usable mild steel remnants at highly competitive prices purchase this material, including scrap steel. Additionally, scrap material can come from the initial extraction process of iron ore, where molten iron is refined and later cooled.

In addition to the cost savings, verified mild steel remnants offer the advantage of less machining waste when remnants closely match the dimensions of the component being machined or fabricated.

Remnants occupy less floor space and are easier to handle than full-size steel plates and bars. If you’re not consistently using large amounts of mild steel in your production process, remnants can be a cost-effective source of your material.

Additionally, considering scrap steel for more minor projects can lead to significant cost savings without compromising material quality. While low-carbon steels are often preferred for their ductility and ease of use, higher-carbon steels are chosen for applications requiring greater hardness and strength.

However, the affordability of mild steel remnants makes them a practical alternative to steels with higher carbon content in many scenarios.

Mild Steel in Modern Primary Steelmaking

Mild steel production typically involves two main methods: the basic oxygen furnace and the electric arc furnace. These modern primary steelmaking processes allow for precise control of mild steel grades’ chemical composition and mechanical properties.

The manufacturing processes can be tailored to produce various steel types with different carbon contents and other alloying elements. This versatility in production methods contributes to mild steel’s widespread use across multiple industries.

Surface Treatments for Mild Steel

Various surface treatments can enhance the properties of low carbon steek. One popular option is galvanized mild steel, which involves applying a zinc coating to the surface. This protective layer significantly improves the steel’s resistance to corrosion, making it suitable for use in outdoor environments and cold weather conditions.

Other surface treatment options include heat treatments and cold forming possibilities, which can alter the surface hardness and other physical properties of mild steel. These treatments expand the range of applications for mild steel products, making them even more versatile in the construction industry and other sectors.
