1. Superior Corrosion Resistance

  • Molybdenum Boost: 2–3% Mo content creates a shield against chlorides (seawater, deicing salts) and sulfuric acid (up to 5% concentration).
  • Crevice Corrosion Resistance: 316L’s low-carbon design (≤0.03% C) prevents corrosion in stagnant environments (e.g., offshore pipeline joints).
  • Pitting Resistance Equivalent (PRE): 316L achieves PRE >24, outperforming 304L (PRE <19) in marine tests.

2. High-Temperature Performance

  • Service Temperature: Withstands up to 925°C (316) and 870°C (316L) without scaling.
  • Thermal Stability: Critical for furnace components, jet engine parts, and nuclear reactors.

3. Hygiene & Biocompatibility

  • Non-Reactive Surfaces: FDA-approved for food/beverage contact (brewery tanks, dairy equipment).
  • Medical-Grade Compliance: 316LVM (vacuum melted) for surgical implants and orthopedic devices.
