DIN 1629 seamless steel pipe has three main grades of St37.0, St44.0, St52.0. Generally, the DIN 1629 standard is not limited to the working pressure value, and the working temperature is limited to below 300 ℃.

ASTM A283 cold rolled steel coil has low and medium tensile strength. The ASTM A283 steel specification covers four structural quality grades of mild steel, grades A, B, C, and D, for general application.

DC01, DC02, DC03, DC04, DC05, DC06 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.

A36 is a carbon structural steel coil whose chemical composition and mechanical properties strictly conform to American ASTM standards. Good mechanical properties, welding performance and corrosion resistance are basically why they are widely used in construction, bridges, machinery manufacturing and other fields.

GB/T 11251 alloy steel is one of the common hot-rolled alloy structural steels. This steel coil is widely used in various applications in bearings/gears of rotating machinery.

1045 cold rolled steel coil is a medium carbon structural steel with good hot and cold workability and good mechanical properties. It is widely used in the industrial machinery manufacturing industry.

ASTM A283 is a carbon steel plate used for general structural purposes. The steel has low and medium tensile strength. The ASTM A283 steel specification covers four structural quality grades of mild steel, grades A, B, C, and D, for general application.

DC01, DC02, DC03, DC04, DC05, DC06 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.

Shipbuilding steel plate refers to the carbon and alloy steel plate used in offshore and marine contructions, common grades are A, B, D, E, AH32/36/40, DH32/36/40, and EH32/36/40 which ranged from different strength.

AISI 1025 steel bar is a medium carbon steel that offers plasticity, workability and strength. The steel contains between 0.22% and 0.28% carbon, so it is stronger than low carbon steel and more workable and malleable than high carbon steel.
