Sandvik demonstrates its development capability

� With over 40 years’ experience, Sandvik is constantly adapting to the changing market conditions and the requirements of its customers by innovating and adding new, more specialised and higher performance products to its already impressive range of steels. A number of new material examples were used including duplex grades, developed to meet the increasing demands on construction materials for oil and gas exploration and production materials; the extensively enhanced machinability Sanmac grades, including hollow bar, which boost productivity for machined components; materials that extend seamless tube life in highly corrosive environments such as urea, ethylene and petrochemical plants, in addition to hydraulic and instrumentation tubing in Sandvik SAF 2304 ® that withstand nearly twice the pressure of standard material tubes.

high tensile strength of 980–1,180 MPa and increases the operating temperature to 90°C (194°F). Another specifically developed hyper- duplex stainless steel is Sandvik SAF 2707 HD ® , designed for service in highly corrosive conditions, such as seawater cooled heat exchangers. It is particularly suited to aggressive, chloride-containing environments and displays excellent resistance to pitting. This makes it ideal for chemical, petrochemical and refinery industries tomeet higher industry demands on performance while maintaining the reliability and safety of equipment. Manufacturing dedicated seamless tube and pipe for the power generation and nuclear industry, Sandvik is set to increase its production capability as a result of significant orders for steam generator tubes for the US and Chinese markets. Its development programme also includes special tubes for high efficiency,

SANDVIK Materials Technology’s stainless steel and advanced materials offers comprehensive seamless tube and pipe product in keeping with its reputation for research and development. The latest hyper-duplex stainless steel, Sandvik SAF 3207 HD ® , optimises material strength and corrosion resistance and extends the properties of Sandvik’s industry standard super-duplex grade, Sandvik SAF 2507. Use of the new grade makes it possible to develop installations and explore new oil and gas fields that were previously thought to be too expensive and technologically unattainable. Developed for use in deeper, more remote subsea umbilicals operating in aggressive environments, Sandvik SAF 3207 has a higher yield strength to withstand increased pressures, facilitating thinner wall umbilicals that reduce reel sizes and lower installation costs. It extends the operating capabilities of hyper duplex materials having an extremely
