The true and false quality analysis of API 5L X56 (L390) PSL2 carbon steel plate

Unlike general steel manufactures, other than regular fresh production, we also have huge stocks. What is more, we offer cutting, welding, drilling, bending, etc. deep processing for the steel materials. That enable us to meets various API 5L X56 (L390) PSL2 carbon steel plate steel sizes and shapes requirements of clients.So, if you have any steel demands, or steel processing needs, please do not hesitate to contact with us. We will try our best to make you stisfied.

API 5L X56 (L390) PSL2 carbon steel plate Shanghai inventory: 12.9*2987*10384, 15*2200*10270, 14*1950*10600, 320*2200*4250, 32*2500*6000, 14*2200*10030, 65*3010*8230, 16*2100*10650, 36*2200*12000, 12.9*2987*10384, 14*1950*10900, 25*2500*12000, 15*2200*10270, 20*2620*11800, 14*1950*10450, 30*2200*12000, 14*2200*10030, 20.9*2851*7000, 20*2933*7300, 14*1950*10500, 50*2200*12000, 31.9*2920*9420, 20*2933*7300.

During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of API 5L X56 (L390) PSL2 carbon steel plate. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.

Oxygen is a harmful element in API 5L X56 (L390) PSL2 carbon steel plate steel. With the increase of oxygen content, the strength of API 5L X56 (L390) PSL2 carbon steel plate steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of API 5L X56 (L390) PSL2 carbon steel plate steel.
