(mm): 200-500; φ200-500;10-90x100-310,The Dimensions (mm) : Module : 100-400; Forgingsφ200-500; Flat steel 10-90 x 100-310, The length according to customer's request.

Features:The steel was purity and organize good after rare earth modification treatment, The steel also was high strength ,wear resistance and high tropism through the double refining process, such as forging processing and good machinability /secondary hardening characteristics at the same time/ temper softening resistance characteristics in the environment of high temperature, hot strong thermal fatigue resistance.

Application: hardness cast aluminum and magnesium alloy extrusion moulding / collar /slider/ embedded mold die/ heart /heart ejection/ pin shaft/ forging die/ mold plastic/ injection mold /the mold plate (high hardness) plunger
