Customizable surfaces such as BA (bright annealing), 8K mirror, and HL (brushed) are available; please specify in advance.
Packed with moisture-proof paper and galvanized iron sheets. Each coil weighs ≤10 tons. Wooden crates are required for fixing during sea transportation.
Regular specifications (0.5-3.0mm×1219mm) are fully stocked, with delivery within 48 hours; the customization cycle for special specifications is 15-20 days.
TIG welding is recommended, using ER308L welding wire. No preheating is required before welding; interpass temperature should be ≤150℃. Post-weld pickling and passivation are recommended.
Walmay will help match the right stainless product form and specification for your application, confirm quantities and packing needs, and provide requested documents based on order requirements.
