What is SUS 304L 2B Stainless Steel Plate?
SUS 304L 2B stainless steel plate is a low-carbon austenitic stainless steel plate with a 2B cold-rolled surface finish, widely used in industries requiring excellent corrosion resistance, weldability, and hygienic performance.
The 2B finish is smooth, uniform, and slightly reflective, making it ideal for chemical, food, marine, and architectural applications.
The "L" in 304L stands for low carbon, which improves weldability and reduces the risk of intergranular corrosion after welding.
Applications of SUS 304L 2B Stainless Steel Plate
Chemical Equipment: Tanks, vessels, heat exchangers
Food & Beverage Industry: Pipes, tanks, processing equipment
Marine Applications: Boat fittings, seawater-resistant components

What is the difference between SUS 304 and 304L?
304L has a lower carbon content (≤0.03%) than 304 (≤0.08%), which improves weldability and reduces intergranular corrosion in welded structures.
Can SUS 304L 2B plate be used in outdoor environments?
Yes, it resists oxidation and corrosion in outdoor, humid, and slightly acidic environments. For applications with high salt content or corrosive chemicals, 316L is recommended.
