Low carbon steel refers to an iron-carbon alloy with a carbon content (C) ranging from 0.05% to 0.25% (some standards extend to ≤0.25% or ≤0.5%). Its microstructure is mainly ferrite and contains a small amount of pearlite. Due to its low carbon content, it is also called mild steel. It is the category with the best plasticity and lowest hardness in the carbon steel family.

Iron (Fe): ≥85%

Manganese (Mn): 0.10%–2.20% (to improve strength and processability)

Silicon (Si): 0.17%–0.37% (deoxidizer)

Impurity control: Sulfur (S) ≤0.050%, Phosphorus (P) ≤0.040% (to reduce brittleness)

Excellent formability and ductility: Compared with high carbon steel, low carbon steel has extremely high ductility and plasticity.

Excellent welding performance: Low carbon steel is the type with the best welding performance among all carbon steels.

King of cost-effectiveness: Simple composition (mainly composed of iron, low carbon, manganese and a small amount of silicon), mature production process.

Good machinability: Although not as easy to cut as lead steel, the overall machinability is good and can be efficiently processed by conventional turning, milling, drilling and other means.

Moderate strength and hardness: Its strength and hardness are relatively low among carbon steels (mainly through cold working hardening can be moderately improved).

Friendly welding process: Almost all common welding methods (arc welding, MIG/MAG welding, resistance welding) are applicable.

First choice for forming processing: Take full advantage of its cold forming advantages for bending, stamping, rolling, etc.

Diverse surface treatment: Effectively improve its corrosion resistance through processes such as galvanizing, painting, powder coating, etc.

Limited heat treatment: Mainly annealing to eliminate cold working stress or improve machinability, and carburizing/carbonitriding treatment of the surface to obtain high hardness and wear resistance.

High recycling rate: Steel is one of the most recycled materials in the world. Low carbon steel is easy and efficient to recycle, significantly reducing the environmental footprint.

Construction and Infrastructure: Rebars, I-beams, angles, sheet piles – the soul of skyscrapers, bridges, roads.

Automotive: Covering body panels, chassis components, non-critical structural parts, taking into account lightweight and cost control.

Industrial Pipes and Containers: Water pipes, gas pipes, storage tanks, boiler shells (low pressure), etc., reliably transport liquids and gases.

Daily Life: From metal furniture, filing cabinets, tool housings, to fasteners such as wire, nails, and bolts, they can be seen everywhere.

Mechanical Equipment: Widely used in the manufacture of gears (low load), shafts (non-critical), racks, housings, and other parts that require good processability and a certain strength.

We are an integrated industrial and trade company that can produce steel independently and reduce costs.

From raw materials to finished products, we control quality throughout the process to ensure that the products meet customer requirements.

The combination of production and sales confidentiality can respond to orders quickly and shorten delivery time.

One-stop service, from consultation to production, and finally to after-sales service, provides all-round support.

We are self-produced, reducing dependence on external price fluctuations. In the face of sudden price increases, we can still deliver quickly and on time.

For inventory steel, we can provide preferential prices.
