CNC-Machined Stainless Steel Components – Technical Parameters

FAQ

1. What materials do you use?

We primarily use 304, 316, and 316L stainless steel for corrosion resistance and durability. Other grades (e.g., 303, 17-4PH) are available upon request.

2. What tolerances can you achieve?

• Standard: ±0.05–0.1 mm (ISO 2768-medium/fine).

• Tighter tolerances (e.g., ±0.01 mm) are possible for critical dimensions.

3. Can you customize parts?

Yes! We offer:

• Custom sizes, thicknesses, and hole patterns.

• Special surface finishes (e.g., mirror polish, sandblasting).

• Additional features (threads, grooves, knurling).

4. What’s the lead time?

• Bulk orders: 30–45 days (depends on quantity).

5. How do you ensure quality?

• CNC machining with ISO 9001-certified processes.

• Dimensional checks (CMM, calipers) and surface finish testing.

• Material certifications (MTRs) provided.

6. Are your parts corrosion-resistant?

Yes! Stainless steel (especially 316/L) offers excellent resistance to rust, chemicals, and high temperatures (up to 800°C/1472°F).

7. What industries do you serve?

Common applications include:

• Automotive (bushings, bearings).

• Aerospace (flange connectors).

• Hydraulics/Pneumatics (seal sleeves).

8. Do you provide coatings or treatments?

Options include:

• Passivation (enhanced corrosion resistance).

• Electropolishing (smoother surface).

• Heat treatment (for hardness).

9. What’s the minimum order quantity (MOQ)?

• Bulk orders: 1000 pieces Negotiable (discounts for large quantities).
