What kind of electrode is used to weld NM400 material meaning

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

The typical hardness of NM500 steel plate is 500 HBW, so it can withstand severe wear. NM500 steel plate is very suitable for working in strong wear environment, such as high strength ore and corrosive materials. NM550 steel plate is a kind of wear-resistant steel plate with an average hardness of 550 HBW. NM400 material meaning Its toughness is the same as that of NM500 steel plate, and it is used in high wear occasions. When the NM500 steel plate is upgraded to NM550 steel plate, the Brinell hardness is increased by 50 units, and the wear resistance life is prolonged without losing the toughness of the NM400 material meaning steel plate.

Compared with ordinary carbon steel plate, manganese steel plate has the following advantages. First, NM400 material meaning, manganese steel plate is convenient for welding and processing. Second, manganese steel plate has good heat resistance, and can be processed into various containers. Third, manganese steel plate has good toughness. It is not easy to fracture and has long service life. Fourth, the performance of manganese steel plate is good at low temperature. It will not fracture because of temperature, so it can be used in cold areas.
