Frequently Asked Questions (FAQ)
-
Q: What is the difference between 316 and 316L stainless steel?
A: 316L has a lower carbon content (max 0.03%) compared to 316 (max 0.08%), which reduces carbide precipitation during welding, making it more resistant to intergranular corrosion. Our sector plates use 316L for superior long-term performance in corrosive environments. -
Q: Can I get a different sector angle than 18°?
A: Yes, we offer custom angles such as 15°, 20°, 24°, or any specific angle required for your filter. Please provide your exact specifications for a quote. -
Q: What hole sizes are available for the precision punching?
A: Standard hole diameters range from 2mm to 12mm. We can also produce non-standard sizes upon request. The hole pattern (staggered or straight) is customizable. -
Q: Do you provide samples before bulk order?
A: Yes, we can supply samples for evaluation. Sample cost is negotiable, and we can refund part of the cost upon bulk order placement. -
Q: What is the typical lead time for production?
A: For standard sizes, lead time is approximately 15–20 working days after order confirmation. Custom orders may require 25–30 working days, depending on complexity. -
Q: How are the sector plates packaged for export?
A: Each sector plate is interleaved with protective material, then packed in sturdy plywood pallets to prevent damage during transit. We also offer custom packaging options. -
Q: Can these plates be used in high-temperature applications?
A: 316L stainless steel maintains good mechanical properties up to approximately 800°C (1472°F) in continuous service. For higher temperatures, please consult our technical team. -
Q: Do you have quality certifications for your products?
A: Our factory follows strict internal quality control procedures. Specific certifications can be provided upon request, depending on the destination market. We recommend contacting us for details.
