ASTM A36 is a common mild steel(carbon structure steel grade). It is widely used in morden industry owning to its cheapest rolling cost and easiest welding. SMA570W seaport buildings used steel, ASTM A36 mild steel is equivalent to grade Q235B under Chinese steel standard, grade S235JR under European steel standard EN 10025-2, grade SS400 in Japanese steel standard. These mild steel plates and sections are commonly bolted and riveted in structural applications.

Generally, the steel plates for boiler and pressure are divided into categories. A516 gr60 carbon steel plates have a maximum thickness that varies on the capacity. The tensile strength, elongation, yield strength, and hardness are the mechanical properties of these plates. Physical and chemical characteristics of the boiler quality plates SMA570W seaport buildings used steel make these a popular choice in the industries. Also, these carbon steel are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built.

Classification of SMA570W seaport buildings used steel, steel plate, including strip steel:
1. Classified by thickness: (1) thin plate (2) medium plate (3) thick plate (4) extra thick plate
2. Classification by production method: (1) hot rolled steel plate (2) cold rolled steel plate
3. Classification according to surface characteristics: (1) galvanized sheet (hot galvanized sheet, electro galvanized sheet) (2) tin plate (3) composite steel plate (4) color coated steel plate
4. Classification by use: (1) bridge steel plate (2) boiler steel plate (3) shipbuilding steel plate (4) armored steel plate (5) automobile steel plate (6) roof steel plate (7) structural steel plate (8) electrical steel plate (silicon steel sheet) (9) spring steel plate (10) others

A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The SMA570W seaport buildings used steel, Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.
