Product Introduction
CK45 Chrome Plated Steel Rod is a chrome-plated steel rod made of high-quality CK45 steel. It's produced with precision, first finely processed, then coated with chromium. This plating enhances its hardness, wear resistance, and corrosion protection. Widely used in machinery and automation equipment, it ensures stable operation and durability.
Product Advantages
Exceptional Wear Resistance
CK45 Chrome Plated Steel Rod features a hard chrome plating thickness of 25±5μm with surface hardness reaching 850-1150HV, offering 4x higher wear resistance than standard steel. The electrochemically bonded chrome layer adheres firmly to the CK45 medium carbon steel base, with bond strength exceeding 20MPa, ensuring durability under high-frequency friction and impact. The tempered base material achieves refined grain structure and compressive strength of 700-850MPa, preventing deformation under prolonged use.
Long-Term Corrosion Protection
The dense chrome oxide layer blocks moisture, oxygen, and chemicals. With porosity below 0.5%, CK45 Chrome Plated Steel Rod provides 2x better corrosion resistance than standard zinc-plated steel, making it ideal for marine or industrial chemical environments while preventing rust-induced performance degradation.
Precision Machining & Stability
CK45 Chrome Plated Steel Rod meets ISO f7 tolerance standards, maintaining diameter accuracy within ±0.01mm, straightness ≤0.2/1000mm, and roundness within half of diameter tolerance. Surface roughness ≤0.2μm (Ra) reduces friction coefficient to 0.12-0.16, cutting operational resistance by 60% for smooth hydraulic and automation system performance.
High-Pressure & Temperature Resistance
Heat-treated CK45 base material delivers tensile strength of 700-850MPa, operating reliably from -20°C to 200°C. The chrome layer remains intact under 50MPa+ pressure, preventing micro-cracks in high-load applications like hydraulic cylinders and stamping equipment.
Extended Lifespan & Cost Efficiency
With an ultra-low wear rate of 0.001mm per 1,000 hours, CK45 Chrome Plated Steel Rod lasts 3-5x longer than standard carbon steel. Reduced friction minimizes external lubrication needs, lowering maintenance costs by over 50%, perfect for 24/7 smart manufacturing operations.
