BW450 B : Baosteel，W：Wear Resistant Steel, 450：Brinell
hardness value
BW450 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.
