316 / 316L Stainless Steel Coil Product Overview

316 / 316L Stainless Steel Coil is a high-performance austenitic stainless steel enhanced with molybdenum, offering superior resistance to pitting and crevice corrosion—especially in chloride-rich environments. Compared to 304 stainless steel, it provides significantly improved durability in harsh conditions such as marine, chemical, and pharmaceutical applications.

316L, the low-carbon version of 316, further improves weldability and reduces the risk of intergranular corrosion, making it ideal for welded structures and critical environments.

Key Features of 316 / 316L Stainless Steel Coil

1. Molybdenum Alloyed for Enhanced Protection

The addition of molybdenum (Mo) greatly improves resistance to localized corrosion, particularly pitting and crevice corrosion.

2. Superior Resistance in Chloride Environments

Performs exceptionally well in environments containing chlorides, such as seawater, salt spray, and chemical exposure.

3. Excellent Corrosion Resistance

Offers strong resistance to acids, alkalis, and industrial chemicals, making it suitable for aggressive environments.

4. Improved Weldability (316L)

316L’s low carbon content minimizes carbide precipitation during welding, ensuring better corrosion resistance at weld joints.

5. Good Strength & Durability

Maintains stable mechanical properties across a wide temperature range, ensuring long-term reliability.

Technical Advantages

• Outstanding resistance to pitting and crevice corrosion
• Long service life in harsh and corrosive environments
