Our SAE 1045 Chrome Plated Rod is a precision-ground, induction-hardened carbon steel shaft with a dense, wear-resistant hard chrome surface—engineered for reliability in hydraulic cylinders, industrial machinery, and mobile equipment worldwide.
Comprehensive Technical Data
Base Material: SAE 1045 (UNS G10450), medium carbon steel
Material Condition: Typically quenched & tempered or induction hardened prior to plating
Diameter Range: 10 mm to 250 mm (standard); larger sizes available on request
Standard Lengths: 1.000 mm to 6.000 mm (cut-to-length service offered)
Diameter Tolerance:
h6/h7 tolerance class: ±0.015 mm to ±0.050 mm (depending on size)
Roundness: ≤0.01 mm for rods under 50 mm OD; ≤0.03 mm for larger diameters
Straightness: ≤0.10 mm per meter (often held to ≤0.05 mm/m for high-precision applications)
Surface Roughness (Ra): 0.05–0.20 µm (as standard); down to 0.025 µm for ultra-smooth variants
Chrome Layer Thickness: 20–100 µm (customizable based on wear requirements)
Adhesion & Porosity: Passes ASTM B571 tape test; low-porosity deposit via controlled bath chemistry
Chemical Composition (SAE 1045):
Carbon (C): 0.43–0.50%
Manganese (Mn): 0.60–0.90%
Phosphorus (P): ≤0.040%
Sulfur (S): ≤0.050%
Silicon (Si): 0.15–0.35%
Iron (Fe): Balance
All rods are ultrasonically tested for internal defects and undergo 100% visual and dimensional inspection before shipment.
Why Choose Us for Your SAE 1045 Chrome Plated Rod Needs?
As a vertically integrated manufacturer of hydraulic components—including Honed Tubes, Hollow Piston Rods, and Hard Chrome Plated Bars—we bring system-level insight to every rod we produce. Unlike commodity suppliers, we understand how piston rod surface quality directly impacts cylinder efficiency, seal wear, and downtime. Our proprietary multi-stage grinding and polishing process, combined with tightly controlled chrome plating baths and post-treatment protocols, ensures consistency that generic vendors cannot match. We also offer value-added services: centerless grinding to tighter tolerances, custom chamfering, thread rolling, and packaging tailored to overseas shipping. With decades of experience serving OEMs in construction, agriculture, and material handling, we don’t just deliver rods—we deliver uptime.
