Advantage and disadvantage analysis of selecting H13 for welding die of stainless steel pipe mould

Stainless steel pipe moulds are usually made of materials such as Cr12MoV, SKD11, D2 and Cr12Mo1V1, and sometimes Cr12 is used for high frequency pipe rollers. In addition, there are a lot of materials can be used, some enterprises will also use copper-chromium alloy, which is all possible.

Whether stainless steel pipe mould or high frequency pipe roller, the pipe mould is generally made of cold mould material, while H13 is a kind of hot mould steel material, so H13 is generally used as the welding die for pipe mould. Because the welding die is an extrusion die and belongs to the hot extrusion mode, the welding die made of H13 material is not easy to deform under the welding high temperature environment, but it is not suitable for other places, because the hardness is not enough.
