Piston Rod – Stainless Steel / Alloy Steel, Hard Chrome Plated, Induction Hardened, Ø[OD] x [Length]mm

Our stainless steel and alloy piston rods are precision-engineered for hydraulic and pneumatic cylinders, offering corrosion resistance, wear protection, and high mechanical strength.

These rods undergo induction hardening followed by hard chrome plating, delivering:

· Mirror-like ID and OD finish for smooth piston travel
· High surface hardness (HRC 58–62)
· Excellent fatigue and corrosion resistance

Ideal for harsh environments, including offshore, chemical, and food-grade applications.

 Typical Steel Grades

·17-4 PH Stainless Steel – high strength, corrosion resistant
·304 / 316 Stainless Steel – excellent corrosion resistance
·Alloy Steel 20MnV6 / 27SiMn – high strength, fatigue-resistant
·Other custom grades available on request

 Common Sizes (Diameter × Length)
