PRODUCT OVERVIEW: 316L MOD STAINLESS STEEL
Advanced Chloride Resistance for Demanding Environments

Material Identity:

  • Common Names: 316L Mod, 316L Enhanced, Super 316L

  • Standard Designations:

    • UNS S31653

    • EN 1.4429

    • ASTM A240 (Grade S31653)

    • Werkstoff Nr. 1.4429

Enhanced Chemistry – The Performance Edge:

Element 316L Mod Range (%) Standard 316L (%) Benefit of Modification
Molybdenum (Mo) 2.7–3.3 2.0–3.0 ↑ Pitting/Crevice Resistance
Nitrogen (N) 0.12–0.22 ≤0.10 ↑ Strength, ↑ Corrosion Stability
Chromium (Cr) 16.5–18.5 16.0–18.0 Base Corrosion Layer
Nickel (Ni) 12.0–14.0 10.0–14.0 Austenite Stability
Carbon (C) ≤0.030 ≤0.030 Weld Integrity

Performance Highlights:
✅ Extreme Chloride Resistance

  • Withstands concentrated chlorides, acids, and sulfides better than standard 316L

  • Critical Pitting Temperature (CPT): ≥35°C vs. 25°C for 316L (per ASTM G48)

✅ Strength-Preserving Corrosion Protection

  • Yield Strength: ≥250 MPa (vs. 170 MPa for 316L)

  • Tensile Strength: ≥530 MPa

  • Maintains ductility: Elongation ≥40%

✅ Fabrication-Friendly

  • Excellent weldability: Use standard AWS ER316L filler

  • No post-weld heat treatment required

  • Cold workability comparable to 316L

Targeted Applications:

  • Offshore wind turbine foundations & seawater piping

  • Chemical tankers & cargo containment systems

  • HIPPI (High-Pressure Acid Leach) mining equipment

  • Pharmaceutical bioreactors & CIP/SIP systems

  • Coastal structural components (bridges, facades)

  • Flue gas scrubbers & waste treatment plants

Product Specifications (Plate):

  • Thickness: 0.5mm – 150mm

  • Widths: 1000mm – 2500mm (custom sizes available)

  • Lengths: 2000mm – 12000mm

  • Surface Finishes:

    • 2B (Standard mill finish)

    • No. 4 (Brushed)

    • BA (Bright Annealed)

    • 8K Mirror Polish

  • Certification: Mill Test Certificates per EN 10204 3.1/3.2

Technical Superiority Metrics:

Property 316L Mod Standard 316L
PREn (Cr+3.3Mo+16N) ≥34 24–28
Crevice Corrosion Pass @ 25°C Fail @ 25°C
Stress Corrosion Resists >60°C Fails at 40–50°C

Why Choose 316L Mod?
▸ 50% longer service life in chloride environments vs. 316L
▸ Reduced maintenance costs in aggressive media
▸ Direct replacement for 316L with no process changes
▸ Qualified for ASME Boiler & Pressure Vessel Code

Supply Capability:

  • Global logistics support

  • Cut-to-size & CNC machining services

  • Just-in-time delivery programs

  • Batch traceability guaranteed
