316L Stainless Steel Plate Product Packaging
316L Stainless Steel Plates are encased in triple-sealed, anti-static polyethylene wraps to safeguard against scratches, dust, and oxidation during transit. Each plate is interleaved with VCI (Vapor Corrosion Inhibitor) paper, which releases protective molecules to prevent rust formation in humid or saline environments—ideal for coastal construction or chemical industries. Bulk orders are secured on heavy-duty, ISO-certified pallets with reinforced steel edges and weather-resistant shrink wrapping, ensuring stability for high-volume shipments. Eco-conscious customers can choose FSC-certified recycled cardboard sleeves or reusable aluminum crates, reducing landfill waste by 90%. Customizable packaging includes QR-code labels for instant access to ASTM A240 compliance certificates and handling tutorials.

FAQ
Q1: How does 316L differ from 316 stainless steel?
A: 316L contains 50% less carbon (0.03% vs 0.08%), eliminating weld decay risks in heavy-gauge applications. Its PREN (Pitting Resistance Equivalent) is 35+ vs 316’s 28.
Q2: Can 316L withstand hydrochloric acid exposure?
A:Recommended for HCl concentrations <5% at 20°C. For higher concentrations, we offer PTFE-lined 316L plates with chemical bonding certification.
Q3: What certifications accompany orders?
Every shipment includes:
Mill Test Certificate (EN 10204 3.1)
SGS Material Composition Report
ISO 14644-1 Cleanroom Packaging Certificate (upon request)
Q4: What’s the lead time for non-standard sizes?
A: 14 days for laser-cut custom sizes (min. 1000kg), with expedited 72-hour processing for emergency medical projects.
Q5: How to restore scratched surfaces?
A: Our proprietary 316L Repair Kit (ISO 8501-3 compliant) enables on-site restoration to original Ra standards.
