Cr12MoV is a high-chromium grade of cold work die steels under GB/T
1299 standard. Cr12MoV can be produced into hot rolled round bars
and square bars, cold-drawing bars,forged bars. We henan bebon can
supply Cr12MoV all of shapes.
According to the market needs, henan bebon supply the oversea
markets for Cr12MoV hot rolled round bars OD 6mm -80 mm and Cr12MoV
forged round bars OD 80 mm - 1200 mm, also Cr12MoV forged square
bars OD 100- 1200 mm. The OD tolerance is about 0-3 mm and length
tolerance is about 0-20 mm.
Cr12MoV round bars are usually produced under the followed
procedures: EAF arc furnace + LF purify affinage + VDF + ingot
steel(bottom gating /argon) + forged + annealing + black polishing
(turnery) + GB/T6402-92 ΙΙ UT test + smooth edges with sawing .
Compared with Cr12, Cr12MoV owns lower C content. Also, Cr12MoV
contains Mo and V two elements. Thus the price of Cr12MoV round
bars is higher price than Cr12 bars.
