application
Food and medical equipment
Applicable to food processing, pharmaceutical equipment, and clean room lining, easy to clean and meets hygiene requirements.
Marine and chemical facilities
Its excellent resistance to chloride corrosion makes it widely used in seawater treatment equipment, chemical containers, and piping systems.
Building and decorative structures
316L Mirror Finish Stainless Steel Sheet has high reflectivity and a beautiful appearance, and is often used in curtain walls, elevator panels, and high-end decoration fields.
Hot load equipment components
It has good high-temperature strength and oxidation stability, and is suitable for continuous high-temperature operation scenarios such as heat exchangers and boiler linings.
advantages
Corrosion resistance
316L Mirror Finish Stainless Steel Sheet contains 2%-3% molybdenum, which has significantly enhanced its pitting resistance through high-purity smelting and homogenization treatment. Its corrosion resistance is about 30% higher than that of 304 steel.
High-temperature oxidation resistance
This product adopts a solid solution heat treatment process, and can still maintain surface stability and structural integrity at intermittent use temperatures up to 870°C (1600°F) and continuous use temperatures up to 927°C (1700°F).
Long-lasting mirror effect
Through fine grinding and repeated electrolytic polishing, the surface finish of 316L Mirror Finish Stainless Steel Sheet is maintained for a long time, and the reflectivity is stable at more than 85%.
