As a certified manufacturer established in 2018, Shandong Sino New Material Co., Ltd. delivers premium stainless steel coils engineered for demanding industrial environments. With our 10,000-30,000 sqm facility and ISO-certified production processes, we supply globally compliant coils across multiple grades including 201, 304, 316, 309S, 310S, and 430. Our annual export value of US$2.5M-US$5M to markets worldwide demonstrates our capability to meet diverse industrial requirements with consistent quality and reliability.
These stainless steel coils feature exceptional properties tailored for industrial applications:
- Corrosion Resistance: Chromium-nickel alloys form protective oxide layers
- High-Temperature Stability: Retains structural integrity up to 870°C (309S/310S)
- Mechanical Strength: Tensile strength ranging 515-760 MPa across grades
- Formability: Excellent bending and shaping characteristics
- Surface Versatility: Multiple finish options for specific applications
Technical specifications vary by grade:
| Grade | Composition | Yield Strength (MPa) | Primary Applications |
|---|---|---|---|
| 304 | 18% Cr, 8% Ni | 215 | Food processing, chemical equipment |
| 316 | 16% Cr, 10% Ni, 2% Mo | 240 | Marine environments, pharmaceutical |
| 430 | 17% Cr, 0.12% C | 310 | Automotive trim, architectural |
Industrial benefits include reduced maintenance costs through extended service life, compatibility with welding and fabrication processes, and compliance with international material standards. Our coils undergo rigorous quality checks including eddy current testing and surface inspection to ensure defect-free delivery.
With 101-200 skilled professionals and overseas offices supporting our operations, we've established supply chains to 11 global regions including North America, Europe, and Southeast Asia. Shipments from Qingdao, Tianjin, or Shanghai ports ensure timely delivery backed by our ISO management systems.

Frequently Asked Questions:
-
Q: What distinguishes 304 from 316 stainless steel coils?
A: 316 contains molybdenum (2-3%) for enhanced corrosion resistance, especially against chlorides, making it suitable for marine applications. -
Q: Can I request custom dimensions?
A: Yes, thickness (0.3-3.0mm) and width (600-1500mm) are customizable based on project requirements. -
Q: What surface finishes are available?
A: Options include 2B (standard matte), BA (bright annealed), No.4 (brushed), and HL (hairline) finishes. -
Q: Do you provide material certification?
A: Mill test certificates confirming chemical composition and mechanical properties accompany all shipments. -
Q: What packaging is used for export?
A: Coils are protected with waterproof wrapping and wooden pallets to prevent transit damage. -
Q: How does 309S/310S perform in high-heat applications?
A: These grades contain higher chromium (22-26%) and nickel (12-15%) for oxidation resistance up to 1150°C. -
Q: What is the minimum order quantity?
A: MOQ varies by specification; contact our team for project-specific quotations.
