- Description
Wear resistant steel are produced from processes of hot rolling, cutting into length and heat treating. The products are characterized with small thickness, good flatness, outstanding wear resistance, excellent toughness, good weldability, good machinablility, consistent property and quality.
Wear resistant steels are developed for applications where high wear resistant performance is required, such as dumper, garbage vehicle, concrete mixer truck, industrial air fan, hopper, crusher, machinery for coal, grain, cement, grab bucket, etc.
With high mechanical strength, NM400 is 3 times to 5 times more than common low-alloy steel plates which can significantly improve surface hardness, usually achieved 360 ~ 450HB.
NM400 Plates are used in various applications like Civil engineering, buildings, and structures, industrial machinery, edge of loaders in the loader industry, wear-resistant lining plate in the crusher industry, slat type conveyors in colliery mechanical industry, lining plates of coal pulverizer in the power industry, lining plate of hopper for heavy handling truck, and various other applications that require long duration, low weight, high performance, and excellent weldability.
The NM400 Wear-Resistant Steel Plates include features such as high strength, high hardness, and high wear resistance, as well as being weldable and bendable.
