BW400 B : Baosteel,W : Wear Resistant Steel, 400 : Brinell hardness value
BW400 steel are produced from processes of hot rolling, cutting into length and heat treating. The products are characterized with small thickness, good flatness, outsanding wear resistance, excellent toughness, good weldability, good machinablility, consistent property and quality.

BW400 steel application :
BW400 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, grabbucket, etc.
