CCS grade E carbon marine steel plate,,CCS grade E carbon marine steel plate., JIS 3101 SS540 is high strength low alloy steel plate sheet, which is widely used in plants building, general mansions and all kinds of construction machinery, such as mines and various types of drilling rig used in construction, power shovel, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers , various types of cranes, hydraulic support, coal mining machinery and equipment and other structures.
CCS grade E carbon marine steel plate,Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. CCS grade E carbon marine steel plate, Q345R pressure vessel steel has good comprehensive mechanical and technological properties The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel,CCS grade E carbon marine steel plate.
The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.
