NM450
NM450 is a highly wear-resistant steel, belonging to the wear-resistant plate series. The "450" in NM450 represents its hardness (usually expressed in Brinell hardness HB), that is, the hardness of the steel plate is about 450HB. "NM" is the first letter of the Chinese word for "NaiMo".

Description:
NM450 is a highly wear-resistant steel, belonging to the wear-resistant plate series. The "450" in NM450 represents its hardness (usually expressed in Brinell hardness HB), that is, the hardness of the steel plate is about 450HB. "NM" is the first letter of the Chinese word for "NaiMo".
NM450 steel plates are usually made of low-alloy steel and high-carbon steel materials, and undergo special treatment of the wear-resistant layer, such as quenching, tempering and other heat treatment processes, to achieve the purpose of improving its hardness and strength. There are usually certain alloy elements on the surface of the steel plate, such as molybdenum, chromium, manganese, etc., which help to improve wear resistance.
Heat treatment process of NM450 steel plate:
Quenching: After the steel plate is heated to a certain temperature, it is quickly cooled to increase its hardness. The quenching process is a key step to improve the hardness and wear resistance of NM450 steel plate.
Tempering: In order to avoid excessive brittleness of the steel plate, the quenched steel plate is usually tempered. The tempering process controls the structure of the steel plate through heating and cooling, improves its toughness and stability, and prevents cracks or brittle fractures during use.
These heat treatment processes can not only enhance the surface hardness of the NM450 steel plate, but also improve its wear resistance and extend its service life while ensuring the toughness of the steel plate.
