A36 is a carbon structural steel plate whose chemical composition and mechanical properties comply with American ASTM standards. This kind of steel plate has good mechanical properties, welding performance and corrosion resistance, and is widely used in construction, bridges, machinery manufacturing and other fields.

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

ASME SA516 standard specification for pressure vessel plates, carbon steel for moderate and lower- temperature service.

A572 steel has four different grades: 42, 50, 60 and 65. Each of these grades differ in their mechanical properties and chemical composition.

EN10025-2 steel plate is a low-alloy high-strength structural steel, which is made of carbon structural steel by adding a small amount of alloying elements.

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.
