Comparison of SUS316 with Other Stainless Steel Grades

Grade Corrosion Resistance Strength Cost
SUS316 Excellent High Higher
SUS304 Very Good High Lower
SUS310S Superior Higher Highest

SUS316 offers improved corrosion resistance compared to SUS304, especially in chloride-containing environments.

Corrosion Resistance and Heat Treatment of SUS316

SUS316 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: 1010-1120°C, followed by rapid cooling
  • Stress relief annealing may be performed at lower temperatures
