316 Stainless Steel Strip
316 Stainless Steel Strip is a versatile and durable material widely used in industries where corrosion resistance is a priority. Known for its excellent performance in harsh environments, this grade of stainless steel is ideal for both industrial and consumer applications. With a high resistance to chloride corrosion, it offers superior durability compared to 304 stainless steel. This product is available in various widths and thicknesses to suit a wide range of applications, from architectural to automotive and chemical industries.
- Product Introduction
316 stainless steel strip is the gold standard for applications requiring exceptional corrosion resistance, particularly in chloride-rich or acidic environments. With 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, it outperforms 304 in marine, chemical, and biomedical settings. Ideal for offshore rigs, pharmaceutical equipment, and coastal architecture, this austenitic alloy combines durability, hygiene compliance, and thermal stability. Available in cold-rolled, annealed, or polished finishes, it meets ASTM, EN, and ISO standards for global industrial reliability.

Competitive Advantages
Molybdenum Edge: Critical for chloride resistance in desalination plants or coastal HVAC systems.
Low Carbon Variants: 316L (0.03% max C) prevents sensitization during welding.
Surface Versatility: Electropolished (Ra ≤0.25 µm) for sanitary uses or No. 8 mirror finish for architectural aesthetics.
Cost-to-Performance Ratio: 20–30% longer service life than 304 in aggressive environments.
Industry Applications
Marine: Boat railings, desalination pipe liners, offshore platform heat exchangers.
Pharmaceutical: Bioreactor vessels, CIP system tubing, vaccine storage tanks.
Food Processing: Brine solution tanks, seafood packaging machinery.
Medical: Orthopedic screws, endoscope components, sterilization trays.
Energy: Flue gas scrubbers, geothermal steam condensers.
Frequently Asked Questions
Q1: When to choose 316 over 316L?
A1: Use standard 316 for non-welded high-temperature applications. Opt for 316L when welding is required to avoid carbide precipitation.
Q2: Can 316 strips handle saltwater immersion?
A2: Yes, but ensure regular passivation. For permanent submersion, consider super-austenitic grades like 904L.
Q3: Is 316 suitable for high-pressure environments?
A3: Absolutely. Cold-rolled H-tempers achieve yield strengths up to 1.030 MPa for hydraulic valve springs.
Q4: How does 316 compare to duplex 2205?
A4: 2205 offers higher strength but lower formability. 316 excels in deep-drawn components like pharmaceutical capsules.
Q5: Can you provide FDA-compliant finishes?
A5: Yes. Our electropolished strips meet FDA 21 CFR 175.300 and 3-A Sanitary Standards.
