Q345 is a steel material. It is a low alloy steel (C < 0.2%), with good comprehensive properties, low temperature properties, cold stamping properties, A514 Gr P QT steel plate welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, A514 Gr P QT steel plate. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.
NM500 wear plate is Chinese abrasion resitant steel. NM500 steel is equivalent to AR500, HARDOX500, XAR500 and so on materials. The surface Brinell hardness of NM500 wear plate is ≥470 HBW. The NM500 steel is consists of max. 0.38% Carbon, 0.70 Silicon, 1.70 Manganese, 0.020 Phosphorus, 0.010 Sulfur, 1.20 Chrome, 1.00 Nickel, 0.65 Molybdenum, 0.050 Titanium, 0.0005-0.006 Boron, min. 0.010 Als, etc.. According to GBT24186, the max. thickness of A514 Gr P QT steel plate, NM500 wear plate is 70mm.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
