Also known as mild steel, low carbon steel has low strength relative to steel with higher carbon levels. Low carbon steel is the most ductile – or machinable – type of carbon steel as well. Chemical alloys can also be added to low carbon steel to enhance desired properties without increasing the material's weight.

High carbon steel is a type of steel with a higher carbon content, usually between 0.6% and 1.5%.
In addition to carbon, high carbon steel also contains a certain proportion of other alloying elements, such as manganese, silicon, phosphorus, sulfur and so on. The content and proportions of these alloying elements are adjusted according to the specific application requirements. High carbon steel has high hardness due to its high carbon content and is suitable for manufacturing parts that require high hardness and strength

DC01, DC02, DC03, DC04 are steel grades of European standard DIN EN 10130, 10209 and DIN 1623, which are specified cold rolled steel. The grades are classified according to the maximum permissible yield strength.

1045 is a medium carbon steel is used when greater strength and hardness is desired than in the "as rolled" condition. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Commonly used in gears, shafts, axles, bolts, studs and machine parts.

1023 cold rolled steel plate is made of low-carbon alloy steel designed for use in applications that require excellent machinability and formability. This type of steel comes with outstanding weldability and machinability, making it an ideal choice for various applications. Its composition mainly includes iron, carbon, and manganese.

ASTM A573/A573M grades include 58, 65 and 70. Steel plates are suitable for structural carbon-manganese-silicon steel plates with three tensile strength ranges. ASTM A573/A573M steel plates are mainly used to improve notch toughness at room temperature.
