S420NL 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.

S460NL 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.

Carbon steel pipe in the performance of the outstanding performance is high yield strength and stress corrosion resistance, has good weldability, welding cold crack and hot crack are less sensitive.
Carbon steel tubes are divided into hot rolled and cold rolled (drawn) steel tubes.
Hot rolled carbon steel tubes are divided into general steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological tubes and other steel tubes.
Cold rolled (dial) carbon steel pipe generally are divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, also includes carbon thin wall steel pipe, alloy thin wall steel pipe, stainless steel pipe, special-shaped steel pipe.

A53 American standard seamless steel pipe is made of high-quality steel billets through hot rolling, cold drawing and other processes. The chemical composition and mechanical properties of this steel pipe comply with the requirements of American standard ASTM A53/A53M.

ASTM A106 grade seamless steel pipe is a widely used low carbon steel and is widely used in the petroleum, chemical and boiler industries. The material has good mechanical properties.

ASTM A335 steel pipe may be hot finished or cold drawn and subjected to the following finishing heat treatment. The specification covers "chrome-molybdenum" seamless pipes with excellent corrosion resistance and high temperature tensile strength.
