HARDOX Wear-Resistant Bolt Product Case Study
Swedish steel, wear-resistant steel HARDOX vault
We will custom-make 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 high 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 of wear resistance. A company was experiencing significant issues with the installation bolts for the inner lining of a rod mill that crushes ore and metal rods, with about two bolts breaking each day. By using bolts made from HARDOX500, the breakage was dramatically reduced to just five bolts per year! Maintenance time was shortened, and operational efficiency significantly increased!! Our company's HARDOX500 bolts were featured in a magazine published by SSAB Swedish Steel, distributed worldwide. Moreover, we received a silver medal! *Bolts are crucial components used for joining parts, and their lifespan can be greatly affected by usage conditions, load states, and bolt shapes. Therefore, detailed discussions are necessary when placing an order.
