Q345B carbon steel material,A633Gr.C,D steel plate A537CL1/A633Gr.C,D steel plate, under ASTM-SAE standard A537CL1/A633Gr.C,D steel plate, under ASTM-SAE standard, we can regard A537CL1/A633Gr.C,D steel plate as Fine-grain structural steels, normalised rolled steel. A537CL1 steel plate is one mainly of Fine-grain structural steels, normalised rolled steel,A537CL1/A633Gr.C,D steel plate is under ASTM-SAE standard equivalent to DIN:TStE355, EN:S355NL, which with a minimum impact energy of 20J at temperatures not lower than -20 degree and the tensile strength of A537CL1/A633Gr.C,D is 4800 to 620 MPa.

Q345B carbon steel material,The main advantage of weather resistant steel plate is its weathering ability. When exposed to the atmosphere, the weather resistant steel plate will form a anti-corrosion film on the surface, and prevent further corrosion to the steel. Thus the weather resistant steel plate almost needs no paint treatment, which is the important measure for carbon steel plates to avoid going rust. Therefore, the maintance cost of weather resistant steel plate is low. The weather resistant steel plate is suitable for outside structure and construction use.

The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be easily obtained during quenching. The second is to improve the tempering stability of the steel, to keep the martensite at a higher temperature, so that the carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.

Q345B carbon steel material,API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.
