Used for chemical containers, industrial pipelines, heat exchangers, manufacturing equipment, and processing machinery.

Applications include vehicle components, exhaust systems, decorative parts, and structural components.

Used in surgical instruments, medical devices, laboratory equipment, and sterilization systems.

Applications include kitchen appliances, refrigerator panels, decorative surfaces, and furniture components.

Stainless steel coil achieves its performance through alloy composition and manufacturing technology:

Chromium reacts with oxygen to create a thin passive oxide layer that prevents further oxidation and corrosion.

Different alloy elements improve specific properties:

• Nickel (Ni): Improves corrosion resistance and toughness
• Molybdenum (Mo): Enhances resistance to chloride corrosion
• Titanium (Ti): Improves high-temperature stability
• Carbon Control: Enhances welding performance

Cold rolling reduces thickness and improves dimensional accuracy, surface smoothness, mechanical strength, and flatness.

Different finishing processes create various surface characteristics including 2B (standard industrial), BA (bright annealed), No.4 (brushed), HL (hairline), and 8K (mirror) finishes.

• General applications → 304 stainless steel
• Marine and chemical environments → 316/316L stainless steel
• Decorative applications → 430 or 201 stainless steel
• High-temperature environments → 310S or 321 stainless steel

• 2B Finish: General industrial applications
• BA Finish: Kitchen equipment and appliances
• No.4 Finish: Decorative and commercial use
• 8K Mirror Finish: Premium architectural applications

• Thin coil (0.1-3mm): Precision manufacturing, decoration
• Medium thickness (3-10mm): Industrial components
• Heavy plate (10-50mm): Structural and engineering applications

Customers can select additional services including cutting, slitting, leveling, skin pass, welding, and custom fabrication to improve production efficiency.
