316L Stainless Steel Sheet — Supplier, Price, Specifications

What is 316L Stainless Steel Sheet / Plate?

316L is the low-carbon version of 316 stainless steel, with molybdenum addition for enhanced corrosion resistance, especially in chloride and marine environments. The "L" grade provides better resistance to intergranular corrosion after welding.

316L stainless steel sheet is the premium choice for applications requiring superior corrosion resistance. With molybdenum addition and low carbon content, 316L outperforms 304 in chloride-rich and marine environments.

Commonly used in marine equipment, chemical processing, pharmaceutical manufacturing, desalination plants, and coastal architecture, our 316L sheets meet ASTM A240 standards and are available in a full range of thicknesses and finishes.

Frequently Asked Questions

What is 316L stainless steel?
316L is a low-carbon molybdenum-bearing austenitic stainless steel. The addition of 2-3% molybdenum gives it superior corrosion resistance compared to 304, especially in chloride and marine environments.
What does the 'L' in 316L mean?
The ‘L’ stands for ‘Low Carbon’. 316L has a maximum carbon content of 0.030% (vs 0.08% for standard 316), which provides better resistance to intergranular corrosion after welding.
When should I use 316L instead of 304?
Choose 316L when corrosion resistance is critical: marine environments, chemical processing, pharmaceutical equipment, food processing with salt/acid, and coastal architectural applications.
Is 316L more expensive than 304?
Yes, 316L is typically 30-50% more expensive than 304 due to the higher nickel content and addition of molybdenum. However, for corrosive environments, the extra cost is justified by much longer service life.
What finishes are available for 316L sheet?
2B, BA, No.4 brushed, 8K mirror, HL hairline, and No.1 hot rolled. For architectural and marine use, No.4 or HL finishes are most common.
Can 316L be welded?
Yes, 316L has excellent weldability. Its low carbon content means it resists intergranular corrosion after welding, making it the preferred choice for welded structures.
What's the maximum temperature 316L can handle?
316L can operate continuously at temperatures up to 870°C (1600°F) in oxidizing environments. For intermittent service, up to 925°C (1700°F).
Do you supply 316L sheets with MTC?
Yes, all our 316L stainless steel sheets come with full Mill Test Certificates showing chemical composition, mechanical properties, and heat number traceability.
