FAQs

 

 

01.What makes AS9100 certified stainless steel aerospace fittings different from industrial grades?

AS9100 certification requires 100% material traceability and more stringent process controls. For Aircraft Stainless Steel Fittings, this means tighter tolerances (±0.005mm) and specialized surface treatments like passivation to prevent intergranular corrosion in high-altitude environments.

02.How do you ensure zero leakage in high-pressure fuel system aerospace fittings?

We utilize 5-axis CNC turning to achieve a micro-polished surface finish of Ra 0.4μm on metal-to-metal seal faces. Every Fuel System Aerospace Fittings batch undergoes hydrostatic pressure testing at 1.5x the rated operating pressure to guarantee seal integrity.

03.Can Dazao provide FAI reports for custom stainless steel aerospace fittings?

Yes. We provide First Article Inspection (FAI) reports compliant with AS9102. This documentation, along with Material Test Reports (MTR) and Certificates of Conformance (CoC), is standard for all our Precision Machined Aerospace Fittings.

04.What are the lead times for 17-4PH stainless steel aerospace fittings?

For prototyping of Custom Stainless Steel Aerospace Fittings, lead times are 7–10 days. Mass production cycles typically range from 3 to 5 weeks, depending on the complexity of the internal geometry and required heat treatment (e.g., H1150).

05.Which thread standards do you support for aerospace connectors?

We specialize in high-precision threads including UNF (Unified Fine) and UNEF (Unified Extra Fine) with Class 3A fit, which is the aerospace standard for vibration resistance. We also machine NPT and BSPP threads for ground support equipment.

06.Do you support low-volume orders for aerospace R&D?

Absolutely. We offer Low MOQ (1-10 units) for aerospace startups and R&D labs needing 316L Stainless Steel Aerospace Fittings for testing, with the capacity to scale to 100,000+ units for tier-1 aviation suppliers.
