- 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.
NM400 is wear-resistant steel with a hardness of 400 HBW, as well as high strength and outstanding impact toughness. The enhanced resistance of NM400 enables considerable savings in all heavy applications where a longer lifespan, reduced weights, energy efficiency, and good weldability are required. All NM400 plates are fully killed and fine-grain treated – trimmed on all four edges, shot blasted, and UT tested in accordance with EN10160 S1E1
