310S Stainless Steel Coil Product Packaging
310S 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 310S perform vs. Inconel 600 in high-temperature applications?
A: 310S provides comparable oxidation resistance up to 1,100°C (2,012°F) at 50% lower cost. Switch to Inconel only above 1,200°C (2,192°F) or for extreme sulfur environments.
Q2: What welding techniques are recommended?
A: Use GTAW with ER310 filler, preheating to 150-200°C (302-392°F) for thickness >6mm. Post-weld heat treatment not required for most applications.
Q3: How to minimize scale formation during hot forming?
A: Specify our Pre-Oxidized Finish – pre-stabilized oxide layer reduces post-processing scaling by 90%.
Q4: What certifications support nuclear industry use?
All coils include:
- ASME Section III (NPCA) compliance
- EN 10204 3.1 Certificate with PMI
- ISO 9712 NDT reports (UT/RT/PT)
Q5: What’s the lead time for custom heat-treated orders?
Solution-annealed coils: 25 days (min. 5 tons).
Quenched & tempered orders: 45 days (min. 10 tons).
