304 Stainless Steel Plate Applications
304 stainless steel plates excel in corrosion-resistant, high-temperature environments, making them ideal for
Shipbuilding: hull structural parts, deck accessories (preferred materials for salt spray environments)
Chemical equipment: reactor liner, piping system (resistant to sulfuric acid/phosphoric acid corrosion)
Medical equipment: surgical instrument holders, sterilization containers (passed ISO 13485 biocompatibility test)
Architectural decoration: coastal building curtain walls, handrails (providing No.4/HL mirror polishing process)
304 Stainless Steel Plate Product Packaging
304 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: What is the difference between 304 and 304L stainless steel plates? How to choose?
A: 304L has a lower carbon content (≤0.03%) and is suitable for scenarios where solid solution treatment cannot be performed after welding (such as large chemical containers) 304 is recommended for conventional environments (about 8% lower cost), and 304L is recommended for highly corrosive environments
Q2: Does the price of stainless steel plates include tax? How to deal with nickel price fluctuations?
A:The quotation is FOB tax-free (13% VAT special invoice can be provided) When the nickel price fluctuates by more than 5%, the price review mechanism is activated and a 3-month price lock contract is signed
Q3: Do you provide cutting and processing services?
A: Basic processing: laser cutting (accuracy ±0.1mm), water jet cutting (no thermal deformation) Value-added services: bending (R angle ≥ 2T), welding (TIG/MIG), surface brushing Charging mode: charging by working hours (additional process flow diagram)
Q4: How to verify the authenticity of the material?
A: Three-step verification method: Spectrometer component detection (free on-site) Third-party SGS/BV test report (issued within 48 hours) Official website anti-counterfeiting code query system
Q5: Minimum order quantity and inventory status?
A: Regular specifications: MOQ 1 ton (regular inventory ≥ 500 tons) Special size: MOQ 5 tons (15-day delivery cycle) Urgent order: Pay 30% expedited fee to insert order production
