Common Customer Questions (Q&A Format)
Q: What is the lead time for stainless steel coils/sheets?
A: Typically 20–60 days, depending on order volume and production schedule.
Q: Do you support non-standard dimensions or special coatings?
A: Yes, we offer customized sizes (e.g., rectangular sheets, special thicknesses) and coatings (e.g., epoxy resin, 3PE anti-corrosion layers).
Q: How is product quality ensured?
A: Third-party inspection reports (e.g., SGS, TUV) and full lifecycle traceability are provided to guarantee compliance with API 5L, GB/T 9711, etc.
Q: What shipping methods are available? Is global delivery supported?
A: Options include sea, land, or air freight. We support containerized or bulk shipping to major global ports.
Q: What surface finishes are available for stainless steel coils/sheets?
A: Surface grades include NO.1 (hot-rolled pickling), 2B (cold-rolled bright), BA (mirror finish), 8K mirror finish, and HL (brushed finish).
Q: Is 310S suitable for high-temperature environments?
A: Yes, 310S can withstand temperatures up to 1150°C, making it ideal for boilers and heat exchangers.
Q: What advantages does duplex stainless steel (e.g., 2205) offer over austenitic stainless steel?
A: Duplex stainless steel combines the corrosion resistance of austenitic steels with the high strength of ferritic steels, making it suitable for high-stress corrosion environments (e.g., chemical pipelines).
Q: Do you provide services to adapt to international standard differences?
A: Yes, we can adjust material specifications, dimensions, and standards (e.g., ASTM vs. GB/T) to meet target market requirements.
