FAQ
Q1: What corrosion resistant steel alloys are available from Chinese suppliers?
A: Chinese suppliers offer a full spectrum: austenitic (304/316), duplex (2205/2507), martensitic (410/420), PH (17-4), and nickel alloys (Hastelloy, Inconel) .
Q2: What certifications should I look for?
A: Look for ISO 9001 certified steel parts supplier . For aerospace, AS9100; for automotive, IATF 16949. Also verify material traceability with Mill Test Certificates.
Q3: Can Chinese suppliers handle complex geometries?
A: Yes. Leading suppliers operate multi-axis CNC machining (3/4/5-axis) and can hold tight tolerances down to ±0.005mm.
Q4: What finishing options are available?
A: Passivation, electropolishing, PVD coating, electroless nickel plating (ENP), PTFE (Teflon) coatings, and ceramic coatings.
Q5: How do I verify supplier quality?
A: Request factory audits (virtual or on-site), first article inspection (FAI) samples, and reference checks. Consider third-party inspections (SGS, TÜV).
Q6: What documentation is provided for material traceability?
A: custom corrosion resistant alloy components should include Mill Test Certificates (MTCs) with traceability to the steel melt.
Q7: How do I protect my intellectual property?
A: Sign a comprehensive Non-Disclosure Agreement (NDA) and include tooling ownership clauses in your contract.
Q8: How do I get a quote?
A: Contact us with your technical drawings, material specifications (ASTM/ISO), finish requirements, and quantity for a detailed RFQ.
