Bright Steel Rod
Bright Finished Forged Steel Piston Rod - ST52/S355 Threaded
Bright-finished piston rod forged from ST52/S355 steel, featuring standard threads (such as ISO metric threads). Forging produces a dense microstructure, and thread rolling strengthens surface hardness in the threaded region. After bright polishing, the surface roughness is ≤Ra 3.2. Suitable for hydraulic systems requiring threaded connections, including the assembly of piston rods and piston heads, providing high-strength fastening and wear resistance.

What Is Forged Steel? Forged steel is steel that has been shaped by applying compressive force — hammer blows, press tonnage, or die pressure — while the metal is at an elevated temperature, typically between 1,100°C and 1,250°C (2,000°F–2,300°F) for hot forging. The mechanical working breaks up ca...
