In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, P265GH equivalent astm material is of high quality? First of all, check whether there are cracks on the surface of the p265gh equivalent astm material plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.

P460NH plate is a weldable fine grain steel in normalized state, which is equivalent to GB6654 grade 15MnVNR. p265gh equivalent astm material, P460NH plate is special steel for pressure vessel. P460NH plate is in accordance with EN10028-3. The steel grades included in this European standard are divided into four quality grades: a) Room temperature quality level (P... N); b) High temperature quality grade (P... NH); c) Low temperature quality grade (P... NL1); d) Special low temperature quality grade (P... NL2).

Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the p265gh equivalent astm material steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the p265gh equivalent astm material steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the p265gh equivalent astm material steel sheet on the truck Good luck.

Hydrogen (H) is the most harmful element in general steel such as p265gh equivalent astm material. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
