304 Stainless Steel Sheet
304 stainless steel is an austenitic stainless steel composed of 18–20% chromium (Cr) and 8–10.5% nickel (Ni), with small amounts of carbon (≤0.08%), manganese (≤2%), and silicon (≤1%). This composition provides excellent resistance to corrosion in air, fresh water, and many mild chemical solutions, as well as good tensile strength (520–750 MPa) and yield strength (205–310 MPa). It maintains ductility and formability across a wide temperature range.
Tip: Avoid prolonged exposure to chloride-rich environments (e.g., saltwater) to prevent localized corrosion.

316/316L stainless steel plates
Both 316 and 316L stainless steel plates are austenitic stainless steels, with their core alloys being chromium (Cr ≥ 16%) and nickel (Ni ≥ 10%). The key difference between the two lies in their carbon content: 316 stainless steel has a carbon content of ≤ 0.08%, while 316L stainless steel (the "L" stands for "Low Carbon") has a carbon content of ≤ 0.03%. This carbon content difference is not only the core difference between the two, but also directly affects their intergranular corrosion resistance and weldability, providing a clear basis for selection in different application scenarios.

Heat Treatment of 316 / 316L Stainless Steel Sheet
1. Annealing (Solution Treatment)
Temperature Range: 1010–1120°C
Process: Heat to the specified temperature, then rapidly cool in water or air.
Purpose: Restores full corrosion resistance and ductility by dissolving carbide precipitates and homogenizing the microstructure.
2. Stress Relieving
Application: Performed after heavy forming, bending, or machining operations.
Purpose: Reduces residual stress and minimizes distortion, maintaining dimensional accuracy for precision components.
3. Hardening
Note: 316 / 316L stainless steel cannot be hardened by heat treatment.
Alternative: Strength improvement can only be achieved through cold working, such as rolling or drawing.
4. Performance Balance
Proper heat treatment maintains the chromium-to-carbon balance, preventing sensitization and intergranular corrosion.
Ensures stable performance during welding, high-pressure vessel operation, and exposure to elevated temperatures or corrosive environments.
Features of 316/316L Stainless Steel Plates
- Corrosion Resistance They offer superior corrosion resistance (surpassing 304), withstanding atmospheric/humid coastal environments and dilute sulfuric/nitric acid. The 2%-3% molybdenum content resists chloride-induced corrosion (e.g., saltwater). 316L (C≤0.03%) further enhances post-weld intergranular corrosion resistance.
- Mechanical Properties Balances high strength and ductility: Tensile strength 515-750 MPa, yield strength 205-310 MPa (ensures load-bearing capacity); elongation ≥40% (enables forming, bending, deep drawing without cracking).
- Weldability Compatible with TIG/MIG/arc welding, no pre/post-weld heat treatment required for most cases. 316L’s low carbon minimizes welding sensitization, ideal for welded structures.
- Temperature Tolerance Maintains stability at up to 800°C (continuous service) and ~925°C (intermittent service), plus good low-temperature toughness (-196°C) for cryogenic applications.
Applications of 316 / 316L Stainless Steel Sheet

Common thicknesses include 0.5 mm, 1 mm, 2 mm, 3 mm, 6 mm, and 10 mm. Standard sizes are 4x8 ft (1219x2438 mm) and 5x10 ft (1500x3000 mm). Custom cutting and polishing are available.
4. Can 316L stainless steel sheet be used for food and medical equipment?
Yes. 316L is food-grade and medical-grade compliant, making it ideal for dairy tanks, kitchen counters, pharmaceutical vessels, and surgical instruments.
5. How corrosion-resistant is 316 stainless steel sheet in seawater?
316 and 316L offer excellent resistance to saltwater, chloride, and acid corrosion, making them suitable for marine structures, desalination systems, and coastal applications.
6. Can 316 stainless steel sheet be welded or formed easily?
Yes. Both grades have good weldability and formability. After welding, solution annealing is recommended for 316 to restore corrosion resistance; 316L usually does not require this step.
7. What is the surface finish of 316/316L stainless steel sheet?
Available finishes include 2B, BA (bright annealed), No.4 (brushed), HL (hairline), and mirror finish, depending on the application — decorative, industrial, or hygienic.
8. How does 316/316L stainless steel compare to 304 stainless steel?
316/316L contains molybdenum, giving it higher corrosion resistance, especially in chloride or acidic environments. 304 is more cost-effective but less durable in harsh conditions.
