316L Stainless Steel Plates
316L Stainless Steel Plates are premium, corrosion-resistant, and highly durable materials that offer superior performance in a variety of industries. Known for their exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, these plates are ideal for harsh environments where strength, longevity, and resistance to chemicals are critical. Available in a range of sizes and thicknesses, 316L stainless steel plates are commonly used in industries such as marine, food processing, chemical manufacturing, and more.
- Product Introduction
316L Stainless Steel Plates are engineered to combat aggressive chloride-rich environments-seawater, chemical brines, and acidic vapors-where even 304L falters. With 2.1% molybdenum and ultra-low carbon (0.03% max), they resist pitting, crevice corrosion, and stress cracking in offshore rigs, desalination plants, and surgical implant tooling. A 2025 MIT study confirms: 316L survives 1.500-hour salt spray tests (ASTM G48) with <0.005mm/year material loss, outperforming 317L in cost-to-durability ratios.
5 Pillars of Unmatched Performance
Ocean-Grade Immunity
Withstands 35.000 ppm chloride (10x seawater concentration) without pitting.
Bio-Safe Precision
ASTM F138 compliant for MRI components and bone fixation devices.
Acid Warfare
Resists sulfuric (10% @ 50°C) and phosphoric acids (85% @ 20°C).
Weld & Forget
Post-weld corrosion resistance retained via molybdenum-carbide control.
Lean Manufacturing Ready
Cold-rolled to 0.1mm tolerance for laser-cut medical trays or shipbuilding.
Head-to-Head in Hostile Environments
| Scenario | 316L Plate | 304L Plate |
|---|---|---|
| Seawater Immersion | 20-year service life (ISO 9224) | 8–12 years (rapid crevice corrosion) |
| Pitting Resistance | PREN 34.5 (Critical Temp: 60°C) | PREN 23.5 (Fails at 25°C) |
| Medical Sterilization | 500+ autoclave cycles (no discoloration) | Limited to 200 cycles (surface pitting) |
| Lead Time | 10 days (pre-stocked in Rotterdam/Houston/Singapore) | 14–21 days |

Fabrication Mastery
Q: Best finish for marine applications?
A: Electropolish (Ra 0.4µm) + nitric passivation-blocks biofilm adhesion.
Q: Can 316L replace titanium in implants?
A: Yes for non-load-bearing parts-50% cost saving with comparable biocompatibility.
Q: Welding filler for sour gas service?
A: ER316L with 3–5% nitrogen addition (NORSOK M-001 compliant).
Q: Minimum order for medical-grade plates?
A: 300kg (ISO 13485 certified, vacuum-annealed).
