p355gh steel thickness technical requirements

The higher the Cr-Mo content in the material P355GH steel thickness, the lower the control of harmful inclusions, the better the hydrogen corrosion resistance. In recent years, China has gradually specialized the materials of pressure vessel equipment, among which the main materials of medium temperature hydrogen resistant steel are 15CrMoR (equivalent to SA387 Gr 12), 14Cr1MoR (equivalent to SA387 Gr 11), and 12Cr2Mo1R (equivalent to SA387 Gr 22).

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the p355gh steel thickness steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

Strip steel is coiled and curved steel plate, which is different from common steel pipes and steel plates. Strip steel has obvious characteristics. First, it is thin and easy to curl, which is convenient for logistics and transportation. Second, the surface quality of p355gh steel thickness, strip steel is good, the luster is bright and it has good flexibility. Third, the strip steel is easy to process. When you need to use it, you only need to straighten the bent part and you can directly process it. Fourth, the precision is high, and the strip steel can be made of plain carbon steel, carbon structure steel, spring steel, tool steel, stainless steel, etc.

Our main specifications of medium and heavy plates are thickness 6.0-180mm and width 1400-2700mm. In addition, the ship steel plate has been approved by the factories of the eight-nation classification society such as CCS, ABS, BV, LR, GL, NK, KR, and DNV. Our p355gh steel thickness, medium and heavy plates are widely used in manufacturing, logistics, and automotive industries such as construction machinery, mold processing, ships, bridges, high-rise buildings, pipeline transportation, automobile girders, automobile bridge shells, and pressure vessels.
