SAF 3207HD

HuaNickel SAF 3207HD and the aforementioned HuaNickel 00Cr27Ni7Mo5N are super duplex stainless steels. SAF 3207HD was developed to meet the demanding needs of deep-sea (water depths of nearly 2500m and pressures above 1500psi). Compared with the aforementioned SAF2507, the increase in the amount of chromium and nitrogen in the steel makes SAF 3207HD steel not only have higher strength to withstand higher applied loads, but also have more excellent corrosion resistance to meet the needs of more demanding corrosive media.
