By refining furnace (VD) + refining electroslag remelting (ESR), the organization is more pure and subtle, excellent corrosion resistance, polishing, good wear resistance, mechanical workability, hardened excellent dimensional stability. 

 Use corrosion-resistant, corrosion on the use of corrosive PVC, acetic acid salts, such as injection molding material or in a humid environment and storage molds. 

 Wear resistance in wear large injection molding materials (including thermoset injection molding) or die longer working hours, such as electronic parts, to give up style meal knives, utensils, etc.. 

 The smoothness of the surface of the production of optical products, such as cameras, sunglasses, chemical equipment and plastic products, etc..
