Elongation: 20% (minimum)
Hardness: 28 – 32 HRC
Impact Toughness: 40 J (minimum) at -20°C

Key Characteristics:

Induction Hardened: The surface of the rod is hardened to increase wear resistance while maintaining a tough core.
Quenched and Tempered (Q+T): This heat treatment process enhances the overall strength and toughness of the rod, making it suitable for high-stress applications.

Typical Applications:

Hydraulic cylinders
Automotive components
Machinery parts
Heavy equipment
