Applications and Industries Using SUS316L

SUS316L is widely used in various industries due to its excellent corrosion resistance:

1. Chemical processing equipment
2. Food processing equipment
3. Pharmaceutical and photographic equipment
4. Marine applications
5. Heat exchangers
6. Pulp and paper industry
7. Textile processing equipment
8. Surgical instruments and implants

Manufacturing Process of SUS316L Stainless Steel

The manufacturing process of SUS316L typically involves:

1. Melting raw materials in an electric arc furnace
2. Refining the molten metal using AOD or VOD processes
3. Continuous casting into slabs
4. Hot rolling to reduce thickness
5. Cold rolling to achieve final dimensions
6. Annealing at 1050°C for 1 hour, followed by water quenching
7. Final surface treatment and quality control

Comparison of SUS316L with SUS316 and Other Grades

SUS316L offers improved resistance to intergranular corrosion after welding or high-temperature exposure compared to SUS316 due to its lower carbon content.

Corrosion Resistance and Heat Treatment of SUS316L

SUS316L exhibits excellent corrosion resistance:

• Highly resistant to pitting and crevice corrosion
• Suitable for use in marine environments
• Resistant to many chemicals and acids

Heat treatment:

• Solution annealing: 1050°C for 1 hour, followed by water quenching
• Can be continuously exposed to temperatures of 427°C – 857°C without significant carbide precipitation
