Why Choose Luyuan as Your Stainless Partner?

Extensive Ready-to-Ship Inventory

As a major stockist, we maintain thousands of tons of stainless steel in various grades and dimensions. This robust inventory allows us to bypass long mill lead times and ship standard materials to your facility immediately.
Comprehensive Surface Processing

Aesthetics and hygiene are critical for stainless steel. Our processing center is equipped to deliver exact surface finishes, from standard 2B and highly reflective Bright Annealed (BA), to architectural No.4 (Hairline/Brushed) and flawless 8K Mirror finishes.
Precision Cutting & Slitting

Stop paying for scrap. We offer custom cut-to-size services for sheets and plates using advanced laser and plasma cutting technologies. For coils, our precision slitting lines deliver narrow strips with tight width tolerances and burr-free edges.
Material Integrity & Traceability

We source exclusively from certified, top-tier stainless steel mills. Every shipment is accompanied by a detailed Mill Test Certificate (MTC), ensuring the chemical composition (Chromium, Nickel, Molybdenum levels) perfectly matches your specified grade.
Protective Packaging

Stainless steel surfaces are valuable and easily scratched. We apply premium PVC or laser-film protection to all processed sheets and coils, and utilize seaworthy wooden pallets to ensure your materials arrive in pristine condition.

Applications of Stainless Steel

Frequently Asked Questions

What is the difference between 304 and 316L stainless steel?

Grade 304 is the most versatile and widely used stainless steel, offering excellent corrosion resistance for general applications. Grade 316L contains the addition of Molybdenum, which drastically increases its resistance to chlorides (like salt water or de-icing salts) and industrial chemicals. The “L” stands for low carbon, which improves weldability.
What do surface finishes like 2B, BA, and No.4 mean?
- 2B: A smooth, moderately reflective cold-rolled finish. It is the standard industrial finish.
- BA (Bright Annealed): A highly reflective, mirror-like finish produced by annealing in a controlled atmosphere.
- No.4 (Brushed/Hairline): A characterized finish with short, parallel polishing lines, widely used for appliances and architectural panels to hide fingerprints.
Do you supply protective film on stainless steel sheets?

Yes. To protect the surface finish during transit and your subsequent fabrication processes (like stamping or bending), we can apply various protective films (e.g., standard PVC, or specialized laser-cutting film) to one or both sides of the sheet.
