HARDOX Wear-Resistant Bolt Product Case Study
Swedish steel, wear-resistant steel HARDOX vault
We will custom manufacture HARDOX bolts that consider special bolts and wear-resistant properties.
【Publication Content - For more details, please refer to the catalog.】 Wear-resistant steel HARDOX is characterized by its high hardness and strength, as well as its excellent impact resistance. Focusing on this property, we custom-manufacture special bolts for attaching and detaching liners and other components that are subjected to harsh operating environments, as well as bolts that require consideration for wear resistance. A company was experiencing issues with the installation bolts for the inner liners of their rod mill, which crushed ore and metal rods, breaking about two bolts a day, causing significant concern. By using bolts made from HARDOX500, the breakage was dramatically reduced to just five bolts a year! Maintenance time has been shortened, and operational efficiency has greatly increased!! Our company’s HARDOX500 bolts were featured in a magazine published by SSAB Swedish Steel and distributed worldwide. Moreover, we received a silver medal for this achievement! *Bolts are crucial components used for joining parts, and their lifespan can be significantly affected by usage conditions, load conditions, and bolt shape. Therefore, detailed discussions are necessary when placing an order.
