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.

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.

ASTM A252 is the standard specification for nominal-wall cylindrical steel pipe piles, where the cylinder acts as a permanent load-bearing member or shell to form a cast-in-place concrete pile. The ASTM A252 specification has three grades: Grade 1, Grade 2, and Grade 3, of which Grade 2 and Grade 3 are commonly used materials.

ASTM A333 is the standard specification for seamless and welded carbon and alloy steel pipe for low temperature applications or other applications requiring notch toughness. This standard covers several grades of ferritic steel: Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11.
