Frequently Asked Questions (FAQ)
-
What is the advantage of an annealed stainless steel ring for mechanical seals?
Annealing softens the material, reduces hardness, and improves ductility. This helps the ring conform better to seal surfaces under pressure, reducing stress cracking and improving sealing performance. -
Can you provide rings with a different inner diameter?
Yes, we offer customizable inner diameters from 10mm to 100mm. Please provide your specific dimensions or drawings for a quotation. -
Do you offer material certifications for the stainless steel?
We can provide mill test certificates (MTC) and material traceability reports upon request. Our ISO9001 system ensures full documentation. -
How are the rings packaged to prevent damage?
Standard packaging includes anti-static poly bags inside sturdy cartons. For large quantities, we use wooden pallets. Custom packaging is available. -
What is the typical lead time for 50-500 pieces?
Standard lead time is 7-15 working days for orders within the MOQ. Larger quantities may require 15-25 days depending on complexity. -
Can you match a specific surface roughness or finish?
Yes, we can adjust surface finish from standard annealed to polished or passivated. Please specify your requirement (e.g., Ra 0.8μm). -
Do you export to countries like the USA or Germany?
Absolutely. Our main markets include North America, Europe, and many other regions. We have experience with international shipping and customs documentation. -
Is the low MOQ of 50 pieces always available?
Yes, 50 pieces is our standard minimum. For first-time customers or sample orders, we can sometimes accommodate smaller quantities; please inquire.
