- Product Introduction
Hardened stainless steel rods aren't just stronger-they're smarter. Through controlled cold-forging and heat treatment (up to 1.050°C followed by rapid quenching), these rods achieve HRC 40–50 hardness while retaining stainless steel's corrosion resistance. Ideal for parts that endure constant friction, shock loads, or abrasive environments, they outperform standard 304 rods by 6x in wear life and carbon steel by 20x in rust resistance. Think hydraulic shafts, food processing blades, or even high-end watch components.
The Hardening Edge
Unique Process:
Cold Work + Aging: Strain-hardened via 30–50% reduction, then aged at 480°C to lock in strength.
Surface Perfection: Post-hardening electropolishing removes micro-cracks, achieving Ra ≤0.2 µm.
Core Consistency: Uniform hardness gradient (±3 HRC) across full diameter.
Why It Outlasts Competitors:
| Challenge | Hardened Rod | Tool Steel | Titanium |
|---|---|---|---|
| Saltwater Corrosion | No pitting after 5+ years | Rusts in months | Excellent |
| Cost per Cycle | $0.03 (food processing) | $0.12 | $0.45 |
| Replacement Frequency | 18–24 months (conveyor guides) | 6 months | 10+ years (low wear) |

Real-World Durability Proof
German Auto Supplier: "Switched to 17-4 PH rods for EV battery module clamps-zero fatigue failures in 100k+ units."
Swiss Watchmaker: "440C rods in our chronograph mechanisms reduced service intervals from 5 to 10 years."
Canadian Food Processor: "Duplex rods in our bone saws lasted 3x longer than tool steel, with no bacterial pitting."
Fabricator's Toolkit
Machining:
Carbide drills only | 60 m/min feed for 17-4 PH | Coolant mandatory.
Welding:
Avoid on hardened areas-opt for mechanical joints (spline, press-fit).
Finishing:
TiN or DLC coatings add 2–3x surface hardness (HV 2.000+).
