FAQ

FAQs

What makes 42CrMo4 better than CK45 for chrome plated rods?

42CrMo4 offers higher tensile strength, better fatigue resistance, and superior impact toughness, especially useful in high-load and high-speed applications compared to basic carbon steels like CK45.
Is 42CrMo4 suitable for continuous-use hydraulic cylinders?

Yes. It performs exceptionally well under repetitive motion and pressure cycles, making it ideal for continuous-duty hydraulic operations in mobile or industrial machines.
Can I use this rod in outdoor or marine environments?

Absolutely. The chrome-plated surface provides good corrosion resistance, and the 42CrMo4 alloy resists stress corrosion cracking better than lower-grade steels.
How does induction hardening affect the rod’s performance?

Induction hardening enhances surface durability (HRC 50–62) while maintaining a tough and ductile core. This dual-layer structure makes it perfect for absorbing shocks without fracturing.
Can you provide custom dimensions or end machining?

Yes. We support custom lengths, machining for piston ends, threaded rod tips, and chamfered edges. Just send us your technical drawing or specs.
