ASTM A588 steel is classified into Class A, Class B, Class C, and Class K. The ASTM A588 steel specification is based on the standard specification for high-strength low-alloy structural steel with a lower yield point of up to 50ksi for applications requiring high strength and corrosion resistance.

Carbon steel plates have many uses and a large amount. They are mainly used in railways, bridges, and various construction projects to manufacture various metal components that bear static loads, and unimportant mechanical parts and general welded parts that do not require heat treatment.

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.

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.

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.

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.
