Summary of carbon steel grades and applications


Is carbon steel better than low carbon steel? Low carbon steel is a kind of carbon steel. Carbon is present in all steels. As long as this carbon is the main alloying element, the alloy is considered to be carbon steel. "Low carbon" steel is another name for low carbon steel. There are other carbon steels with different carbon content. Which is better depends on the use of steel.

More than 1.5 billion tons of steel are produced each year for various products, such as sewing needles and structural beams of skyscrapers. Carbon steel is the most commonly used alloy steel, accounting for about 85% of all American production. The carbon content of the product is within the range of 0-2%. This carbon will affect the microstructure of steel, making it have legendary strength and toughness. These alloys also contain small amounts of manganese, silicon and copper. Low carbon steel is a commercial term for low carbon steel, in which the carbon content is in the range of 0.04-0.3%.

Carbon steel category

Carbon steel can be classified according to the chemical composition and characteristics of the product. Low carbon steel also belongs to the category of low carbon steel, because its carbon content is similar. Ordinary carbon steel does not contain alloy and can be divided into four categories:

1. Mild steel

The carbon content of low carbon steel is 0.04-0.3%, which is the most common carbon steel grade. Low carbon steel is also considered as low carbon steel because it is defined as having a low carbon content of 0.05-0.25%. Low carbon steel has ductility and high plasticity, which can be used for automobile body parts, plates and wire products. At the high end of the low carbon content range, plus up to 1.5% manganese, mechanical properties are suitable for stamping parts, forgings, seamless tubes and boiler plates.

2. Medium carbon steel

The carbon content range of medium carbon steel is 0.31-0.6%, and the manganese content range is 0.6-1.65%. This steel can be heat
