NORSOK approved for our D59 Super Duplex

Updated: Mar 7

We are very happy to announce that we have just received our NORSOK approval to produce strain hardened UNS 32760 Super Duplex for D59/D59L Rev 3 fasteners. Offshore Stainless Supplies are the only cold drawn bar manufacturer in the UK to be awarded this prestigious accreditation, reinforcing our position as the UK’s most trusted and reputable manufacturer and stockholder of cold drawn stainless steel and nickel alloy bars.


NORSOK standards are developed by the Norwegian petroleum industry to ensure adequate safety, value adding and cost effectiveness for petroleum industry developments and operations. We like nothing more than learning about the uses of our strain hardened bars and working with our customers to support the engineering challenges they present to us. For further details contact our team, and let us know how we can help you at the developmental stage of your projects.
