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 steel is an ideal material for heavy machinery manufacturing.
