  • Elongation– is significantly better than 12.9 carbon steel. Despite its high strength, elongation is comparable with A4-70 (minimum 0.4 x d).
  • Excellent corrosion resistance – PRE >34, compared with A4 (316L) that has PRE 25.
  • Very good fatigue properties – compared to A4 and carbon steel 12.9.
  • Lower thermal expansion coefficient– compared with austenitic stainless steels.
