Custom Zinc Plated Q235B Steel Tractor Hydraulic Rods Precision Machined Components

Product superiority

Crafted from ASTM A36 steel with electrolytic zinc coating (ASTM B633), these hydraulic rods withstand 500salt-spray hours to combat fertilizer/mud corrosion in farm operations. Precision-machined to Ra≤0.8μm surface smoothness minimizes seal wear, extending maintenance cycles. Engineered for -30°C~120°C pesticide-exposed environments, our customizable rods (200-2000mm length, ±0.05mm tolerance) eliminate downtime through direct OEM-compatible replacements while reducing rust-induced hydraulic failures by 68%.

Application scenarios and pain point solutions

1. High intensity farming environment
Scenario: Hydraulic lifting system for deep tillage plow and rotary tiller
Pain point: Sulfides/fertilizers in the soil accelerate corrosion, and traditional rods will rust and get stuck after 3 months
Solution: Zinc coating+hard chrome polishing, surface hardness HV600, resistant to plowing impact times>500000 times

2. Wet/salt spray environment
Scene: Rice field harvester, coastal area tractor
Pain point: Salt water immersion causes ordinary coating to bubble for 72 hours
Solution: Closed microporous chromium layer (porosity<5/cm ²), salt spray test for 1000h without red rust

3. High temperature hydraulic system
Scenario: Hydraulic drive for silage compactor and drying equipment
Pain point: Oil temperature>80 ° C accelerates seal aging
Solution: Coating substrate adhesion>15MPa (ASTM D3359), heat-resistant fluororubber seal (-30 ° C~+200 ° C)
