Recently, our company received an inquiry from a customer from Wuhu, Anhui, and wanted to purchase a batch of rolls. After we checked the drawings, the design of this batch of rolls and our welded pipe molds were somewhat similar, but not exactly the same. The material requirement was K110, or other materials of the same standard. After we checked the information, the K110 material corresponds to Cr12Mo1V1, SKD11, D2, etc. Each country or region has a different title.
