- Material-Stainless Steel:
- 18/12 chrome-molybdenum steel with very low carbon content, protected from inter-granular corrosion
- Fit in environments where 18.10 steels stand up corrosion, excepted those involving nitric acid
- 2/2,5 molybdenum content allowing its use in more applications than those complying with 18.10 steels.
