Chemical Composition and Mechanical Properties of 316LN Stainless Steel

316LN (S31653) is a low-carbon, nitrogen-enhanced version of Type 316 stainless steel with the following composition:

Mechanical Properties:

Applications and Industries Using 316LN Stainless Steel

316LN stainless steel is widely used in:

1. Chemical processing equipment
2. Oil and gas industry
3. Marine applications
4. Pharmaceutical production
5. Food processing equipment
6. Pressure vessels and heat exchangers
7. Applications with high magnetic fields

Corrosion Resistance and Performance Benefits

316LN offers excellent corrosion resistance, particularly in chloride environments. The addition of nitrogen enhances:

• Resistance to pitting and crevice corrosion
• Mechanical strength through solid solution hardening
• Resistance to sensitization

Manufacturing Process and Available Forms

316LN is typically produced through controlled rolling processes. Available forms include:

• Plates
• Coils
• Sheets
• Rods

Welding and Fabrication Considerations

316LN has excellent weldability due to its low carbon content. Key points:

• Post-weld heat treatment is generally not required
• Standard fusion and resistance welding methods can be used
• Filler metals should match or exceed the alloy content of the base metal

Comparison of 316LN with Other Austenitic Stainless Steel Grades

316LN offers superior strength and corrosion resistance compared to 316L:
