Explore our premier range of industrial steel coils, plates, and customized fabrication solutions manufactured under strict global standards.
In the global metallurgical supply chain, stainless steel coils represent a cornerstone material for automotive engineering, structural architecture, energy systems, and high-precision tooling. Selecting the right Chinese manufacturing partner involves analyzing dynamic parameters: raw material sourcing stability, rolling tolerances, precision finishing capabilities (such as 2B, BA, No.4, and Hairline), and compliance with international standards (ASTM, EN, JIS, and DIN).
China's steel production volume is backed by technological integration. Top-tier mills deploy multi-roll cold rolling mills (such as 20-high Sendzimir mills), automated AGC (Automatic Gauge Control) systems, and continuous annealing lines. This technical framework ensures thickness tolerance variations are kept within microns, while achieving flatness parameters that standard mills cannot match.
Furthermore, integration with raw material ports and refining centers in industrial hubs like Ningbo allows manufacturers to mitigate logistics overheads and volatile material spot prices. This ensures stable FOB/CIF pricing for global buyers, even during complex macroeconomic cycles.




Selecting a stainless steel grade requires evaluating corrosion resistance, mechanical properties, and thermal limitations. The table below outlines the primary alloys processed at Puppet Steel:
| Alloy Grade | Crystalline Structure | Key Alloying Elements | Primary Attributes | Industrial Application Scenarios |
|---|---|---|---|---|
| AISI 304 / EN 1.4301 | Austenitic | 18% Cr, 8% Ni | Excellent formability, basic corrosion resistance | Food processing, architectural cladding, kitchen equipment |
| AISI 316L / EN 1.4404 | Austenitic | 16% Cr, 10% Ni, 2% Mo | Superior chloride pitting resistance, low carbon | Marine hardware, chemical reactors, pharmaceutical tools |
| AISI 430 / EN 1.4016 | Ferritic | 16-18% Cr, <0.12% C | Magnetic, good thermal conductivity, economical | Domestic appliances, automotive trim, combustion chambers |
| AISI 201 | Austenitic (Low-Ni) | 15% Cr, 1% Ni, 5.5% Mn | High work-hardening rate, cost-effective | Decorative piping, structural components, handrails |
