Sandvik has received StatoiL approval for its stainless steel bar in full accordance with the Norsok M650 Rev 3 for use in oil and gas applications. The approval covers Sanmac SAF 2205 – UNS S31803/S32205 in sizes from 20 to 260mm and Sandvik SAF 2507 – UNS S32750 in size ranges from 20 to 250mm. The approval is recognised by StatoiL and is effective until 2012. Both grades are duplex steels, which combine high strength with corrosion resistance. They have more than twice the strength and lower thermal expansion than austenitic steels, making them fit into applications in the oil and gas industry, seawater services, refineries and petrochemical plants. Bar products in Sanmac SAF 2205 provide machining properties, which lower machining costs and significantly increase productivity. This is achieved without compromising the material’s corrosive resistance and mechanical strength. The approval covers an increased programme of sizes of bar and all are stock standard items.
