Applications and Industries Using SUS317 Stainless Steel

SUS317 is widely used in various industries due to its excellent corrosion resistance:

1. Chemical and petrochemical processing
2. Pulp and paper industry
3. Marine applications
4. Food and beverage processing
5. Pharmaceutical manufacturing
6. Oil and gas sourcing

Manufacturing Process of SUS317 Stainless Steel

The manufacturing process of SUS317 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. Heat treatment: 2100-2300°F for hot working, avoiding temperatures below 1700°F

Comparison of SUS317 with Other Stainless Steel Grades

SUS317 offers superior corrosion resistance compared to SUS316 and SUS304 due to its higher molybdenum content.

Corrosion Resistance and Heat Treatment of SUS317

SUS317 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:

• Does not respond to hardening heat treatments
• Solution annealing: 1050-1150°C, followed by rapid cooling
