316 Stainless Steel Coil (UNS S31600)
Engineered to excel in chloride-rich and acidic environments, 316 stainless steel coil combines 18% chromium, 10% nickel, and 2-3% molybdenum to deliver superior pitting and crevice corrosion resistance. Certified to ASTM A240/A480 and ISO 15156, this molybdenum-enhanced austenitic alloy is the go-to choice for marine hardware, chemical processing, and coastal architecture where standard grades fail.

316 Stainless Steel Coil Product Packaging
316 stainless steel coils are packaged in triple-sealed anti-static polyethylene packaging to prevent scratches, dust and oxidation during transportation. Each package is lined with VCI (vapor rust inhibitor) paper, which releases protective molecules to prevent rust in humid or salty environments, ideal for coastal construction or chemical industries. Bulk orders are secured on ISO-certified heavy-duty pallets with reinforced steel edges and weather-resistant shrink wrap to ensure stability for large-volume shipments. Environmentally conscious customers can choose FSC-certified recycled cardboard boxes or reusable aluminum packaging boxes, which can reduce landfill waste by 90%.

FAQ
Q1: How does 316 differ from 316L coils?
A: 316L (0.03% max carbon) prevents sensitization in welded thick sections (>6mm). Use 316 for non-welded or thin-gauge applications requiring higher strength.
Q2: What surface finishes prevent marine biofouling?
A: Electropolished (Ra ≤0.5μm) or PTFE-coated coils reduce biofilm adhesion by 80% vs 2B finish.
Q3: Are your coils compliant with offshore standards?
Yes, all coils include:
– NACE MR0175 sour service report
– DNVGL-OS-B101 certification for marine use
– 3.2 Material Certificate with traceability
Q4: What’s the MOQ for custom widths?
Standard: 3 tons. Custom widths: 5 tons (lead time 18 days). Slitting tolerance: ±0.3mm.
Q5: How to address transport-induced surface contamination?
A: Opt for our PeelGuard™ packaging – self-removing adhesive film with 99% defect-free unwrapping.
