• Corrosion Test(Used under seawater for 10 years)
• 
• SUS316L HiMo,which is used for SNSX, reduced carbon and increased Cr, Ni and Mo and has excellent corrosion resistance. Lower carbon enable good resist for intergranular corrosion resistance. More contained Cr and Mo improved better resist for pitting corrosion resistance. Furthermore, higher Ni contained has effect for reducing the risk of Stress Corrosion Cracking. This graph shows that no corrosion under CR3 when it's used under circumstance the same as seawater for 10 years.
