Wear-resistant steel plate
Wear-resistant steel NM450 is a high put on-resistant high-finish varieties, with good cutting, bending, welding efficiency. This type of product has been mated for properly-recognized home engineering equipment factories in mass as a super substitute of costly imported put on-resistant plates.
M is “wearable” within the “grinding” the first phonetic alphabet.450 Brinell hardness HB worth. (450 hardness is a broad, domestic NM450 hardness worth is round 450).
The premise of the steel plate has an excellent influence toughness and welding performance with out lack of energy. It is a home metal standard in China for manufacture of Excavators, loaders, bulldozers bucket plate, blade board, facet edge plate.
NM450 put on resistant metal plate is widely utilized in engineering equipment, mining equipment, coal mining equipment, environmental protection machinery, metallurgical equipment, grinding tools, bearings and other elements.

NM400:
Performance characteristics: NM400 wear-resistant plate belongs to high-strength wear-resistant steel plate, which has excellent wear resistance and good impact performance. Its wear resistance is 12-18 times higher than low-carbon steel, 5 times higher than stainless steel and high manganese steel, and 1 time higher than as cast high chromium iron, thanks to its special alloy composition and heat treatment process.
Application field: Widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery and other industries. For example, as wear-resistant components for loaders, bulldozers, excavators such as bucket plates, side blade plates, bucket bottom plates, and blades, as well as wear-resistant parts such as chutes, screen plates, coal silos, hoppers, fans, and pipelines in cement plants, power plants, and steel industries.
NM450:
Performance characteristics: NM450 wear-resistant plate has higher wear resistance and strength compared to NM400, suitable for more severe wear environments. It can provide longer service life and better impact resistance.
Application areas: Suitable for heavy-duty wear-resistant components in coal yard operations and cement plants, such as chute linings, cyclone dust collectors, powder selection machine blades, as well as engineering machinery and loading and unloading equipment components that require stronger wear resistance.
NM500:
Performance characteristics: As the highest level wear-resistant plate in the series, NM500 provides the highest wear resistance and impact strength, suitable for extreme wear and heavy load conditions. Its alloy composition is carefully designed to achieve the best balance of wear resistance and toughness.
Application field: Suitable for situations that require extremely high wear resistance and service life, such as wear-resistant lining plates for mining equipment, crusher, heavy-duty transportation equipment, as well as heavy-duty mechanical components that need to withstand high stress wear.
