NM450 Description

Wear-resistant steel NM450 is a high wear-resistant high-end varieties, with good cutting, bending, welding performance. Wear-resistant steel (Abrasion Resistance Steel ) is widely used in engineering, mining, construction and agriculture machinery products under extremely harsh working conditions with the requirement of high strength and high wear resistance, such as bulldozers, loaders, excavators, dump trucks and various mining machinery, etc. This kind of product has been mated for well-known domestic engineering machinery factories in mass as an ideal substitute of expensive imported wear-resistant plates.

NM450 Introduction

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). Katalor supply NM450 put on-resistant metal plate with good price and quality.

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.

GBT24186 NM450 high power abrasion resistant metal plates mainly provides protection for occasions or parts that have to be wear resistant.

The grade is mixed with good resistance property towards corrosion. This serves excessive efficiency in decreasing environments even at excessive temperatures. Steel plates resist distortion when it comes to influence loading when the temperature gets greater.

NM450 Application

Wear resistant (abrasion resistant) steel plate is strong steel materials for wear resistant, widely used in the bad working conditions, demanded of high strength, high-wear-resisting performance in engineeing, mining, construction, agriculture, port and metallurgical machinery products.

Therefore, solving wear and prolong the used life of mechanical equipment and components becomes the first consideration in the desiging, manufacturing and using.

Loading machines, dredgers, skip cars, conveying plants, dump trucks, cutting edges, knives, breakers, crushers, sieves, feeders, measuring pockets, journals, buckets, gears, sprockets, loaders industrial trucks, lorries, bulldozers, excavators, slurry pipe systems, screw conveyors, presses etc.
