One: NM450 is read as wear-resistant four five zero, which belongs to the wear-resistant steel plate (wear-resistant plate) series. nm - indicates wear-resistant use"Resistant"with"Grinding"The first letter of the word Chinese pinyin. 450—indicates the average Brinell hardness of this steel plate.
2: NM450 is a kind of wear-resistant steel plate, is a high-strength wear-resistant steel plate, widely used in construction machinery, mining machinery, coal mining machinery, environmental protection machinery, crushers, crushers, dump truck carriages, metallurgical machinery, hoists, sprockets, etc. are also commonly used as yield strength 700MPa high-strength structural steel.
Three: NM450 steel plate implementation standard: GB T 24186-2009
Four: NM450 steel plate delivery status: NM450 is delivered in quenched, quenched tempered (quenched and tempered), TMCP+ tempered, tempered or hot-rolled state.
Five: Introduction to the performance indicators of NM450 steel plate.
NM450 steel plate itself not only has high strength, but also has certain toughness, fatigue resistance, impact resistance, corrosion resistance, low temperature impact resistance, and welding and easy processing of steel plate comprehensive high-quality properties. NM450 steel plate has also been unanimously praised and recognized by the manufacturing industry because of its own high-quality performance.
Six: Introduction to the use of NM450 steel plate.
Mining machinery and equipment and other equipment: fan blades, cyclone dust collectors, drill bit stabilizers, etc.; Cyclone dust collectors, fan blades and linings, etc., all require wear-resistant steel plates with good wear resistance and corrosion resistance; Hopper liners, dump truck bodies, etc., require wear-resistant steel plates with good wear resistance and corrosion resistance; baffles, blades and other components; concrete mixing furnace, brick making machine mold plate and other components; loaders, excavators, bucket floors, rotary drilling rig drill pipes and other components; Scraper liners, conveying elbows, etc. also need wear-resistant steel plates with good wear resistance and corrosion resistance. The steel used for machinery such as ash ducts, burners of burners, and guide vanes of separators is made of wear-resistant steel plates.
The reason why NM450 steel plate is widely used in the manufacturing industry is because NM450 steel plate itself has a variety of high-quality properties, and the display of high-quality performance in the process of use has also been unanimously praised and recognized by the manufacturing industry.
