316 Stainless Steel Coil elevates corrosion resistance with its 2–3% molybdenum-enriched austenitic structure, outperforming 304 stainless in aggressive environments. Engineered to withstand saltwater immersion, acidic chemicals, and industrial pollutants, it delivers unmatched longevity for marine hardware, pharmaceutical equipment, and coastal architecture. Its passive chromium oxide layer self-repairs, ensuring <0.001 mm/year corrosion rates in 3.5% NaCl (ASTM G48 Method A validated).

Material Science Breakdown

Elemental Superiority

Molybdenum (2–3%): Blocks chloride-induced pitting/crevice corrosion in seawater.

Nickel (10–14%): Stabilizes austenite for cryogenic toughness (-200°C capable).

Chromium (16–18%): Forms Cr₂O₃ barrier against oxidizing acids (HNO₃, H₂SO₄).

Low Carbon (≤0.03%): Prevents sensitization in welded joints (ASME Section VIII approved).

Surface & Processing Excellence

2B Cold-Rolled Finish: Ra ≤0.3μm for hygienic surfaces (ISO 20340 compliant).

BA (Bright Annealed) Finish: Reflectivity ≥90%, ideal for architectural facades.

No.4 Brushed Finish: Aesthetic uniformity with 120–180 grit directional polish.

Technical Expertise Corner

Q1: Welding best practices for seawater applications?

A: Use ER316L filler with Ar + 2% CO₂ shielding; post-weld pickling (ASTM A380) to restore corrosion resistance.

Q2: Surface treatment for high hygiene?

A: Electropolish to ≤0.25μm Ra (ASME BPE-2019) for bacterial resistance.

Q3: 316 vs. 316L differences?

A: 316L has lower carbon (≤0.03%) to prevent weld decay; choose L-grade for welded structures.
