Bi-Metal Bearings
Product Description
Hardened & Tempered Steel Strips are high-carbon steel materials processed through controlled heating, quenching, and tempering to achieve high hardness, toughness, and dimensional stability. These strips are widely used in motor and pump manufacturing for applications requiring spring action, high wear resistance, and strength. They offer excellent fatigue resistance and are suitable for stamping, cutting, forming, and fabrication processes.
