介绍 | Sandvik SAF 3207 HD is a hyper-duplex (austenitic-ferritic) stainless steel for service in highly corrosive conditions where also high mechanical strength is necessary. This makes the grade ideal for applications such as deepwater umbilicals. Sandvik SAF 3207 HD is characterized by:
Applications Sandvik SAF 3207 HD hyper-duplex steel has been developed for deepwater umbilicals; an application with extreme requirements on pitting and crevice corrosion resistance, mechanical strength and fatigue properties. Offering greater yield strength, greater corrosion resistance and superior fatigue properties compared with super-duplex steels, Sandvik SAF 3207 HD hyper-duplex steel is also an excellent material choice for a range of other oil and gas applications. For example, when resistance to hydrogen sulphide (H2S) is a requirement, such as in raw seawater injection, control lines and chemical injection lines, Sandvik SAF 3207 HD offers high reliability and operational safety leading to lower operating costs. |
