1. What is the difference between 316L and 304 stainless steel plates?
316L contains 2–3% molybdenum, providing significantly better resistance to chlorides, seawater, and aggressive chemicals than 304. It is the preferred material for marine, chemical, and petrochemical applications.
2. Why is 316L widely used in the petrochemical industry?
316L offers excellent resistance to corrosion caused by acids, chlorides, and other aggressive chemicals. Its low carbon content also reduces the risk of intergranular corrosion after welding, making it suitable for pressure vessels, pipelines, and processing equipment.
3. What does "Annealed and Pickled" mean?
Annealing restores the material's ductility and relieves internal stresses after hot rolling. Pickling removes oxide scale from the surface, producing a clean surface that improves corrosion resistance and prepares the plate for further fabrication.
4. Is this stainless steel plate suitable for welding?
Yes. ASTM A240 316L stainless steel plate has excellent weldability and can be welded using common welding methods such as TIG, MIG, and arc welding. Its low carbon content helps minimize carbide precipitation during welding.
5. Can you provide custom sizes and cutting services?
Yes. We offer custom thicknesses, widths, lengths, and precision cutting services, including laser cutting, plasma cutting, waterjet cutting, and CNC machining according to customer drawings.
6. What international standards does this product comply with?
Our 316L stainless steel plates are manufactured in accordance with ASTM A240, ASTM A480, EN 10088, and JIS G4304, ensuring reliable quality and international compatibility.
7. Is 316L stainless steel suitable for seawater applications?
Yes. Thanks to its molybdenum content, 316L provides much better resistance to seawater corrosion than 304. However, for continuous immersion in highly aggressive seawater, duplex stainless steels such as 2205 may offer even greater corrosion resistance.
8. What surface finish is supplied?
This product is supplied in a hot rolled, annealed and pickled condition, typically with a No.1 finish, which is commonly used for industrial fabrication, pressure vessels, and chemical processing equipment.
9. What certifications can you provide?
We can provide Mill Test Certificate (EN 10204 3.1), material traceability documents, and third-party inspection reports upon request.
10. Why choose your company as a stainless steel plate supplier?
- Factory-direct pricing with stable quality
- Large inventory for fast delivery
- ASTM, EN, and JIS compliant materials
- Custom cutting and processing services
