Electropolished Stainless Steel 304 CNC Machining Parts For
Tractors And Seeders
Advantages of Stainless Steel CNC Machining Parts:
1. Excellent Corrosion Resistance
Stainless steel contains chromium, which forms a passive oxide
layer, making it highly resistant to rust and corrosion.
2. High Strength and Durability
Stainless steel parts can withstand high stress and load, making
them suitable for structural and mechanical applications.
3. Precision and Complexity
CNC machining can achieve high precision, often within ±0.001
inches (±0.025 mm).
4. Hygienic and Easy to Clean
Stainless steel has a smooth, non-porous surface that prevents
bacterial growth.
Popular Types of Stainless Steel For CNC Machining:
| Grade | Type | Machinability | Key Properties |
| 304 | Austenitic | Moderate | Excellent corrosion resistance, good weldability, non-magnetic |
| 316 | Austenitic | Moderate | Superior corrosion resistance (especially to chlorides),
non-magnetic |
| 303 | Austenitic | Excellent | Improved machinability (added sulfur), good corrosion resistance |
| 17-4PH | Precipitation-Hardening | Good | High strength, excellent corrosion resistance, heat-treatable |
| 410 | Martensitic | Good | High strength, moderate corrosion resistance, magnetic,
heat-treatable |
| 430 | Ferritic | Fair | Good corrosion resistance, magnetic, lower cost |
| 2205 | Duplex | Moderate | High strength, excellent corrosion resistance, good weldability |

Tips for Stainless Steel CNC Machining Parts Maintenance:
Regularly clean stainless steel components to avoid surface
contamination that can lead to rust. A simple wipe-down with a mild
detergent and water is often sufficient, followed by a rinse and
drying. Avoid contact with chlorides or harsh chemicals that can
cause pitting or staining, especially in grades like 316. Applying
a protective coating or polish periodically can enhance surface
resistance to oxidation and prolong the metal’s shine.
