Bead welding dies with alloy is a way to bead weld alloy steel or hard alloy on the normal carbon structure steel matrix used as the woking area, so that the life and durability of dies can be improved and the cost can be reduced. 用合金堆焊模具,是在普通碳结构钢的基体上堆焊合金钢或硬质合金作为模具工作部分,以提高模具寿命及耐用度,降低模具成本。
But the wear resistance of lower alloy tool steel dies can not be raised by gas nitriding. 低合金钢模具,不能用气体渗氮提高耐磨性。
