SAF 2205™+, a New Generation Duplex

As technology evolves and applications become more advanced, the materials we use come under increased pressure to perform better.

Marcus Hillbom, Technical Marketing Manager for Sandvik Materials Technology, knows how these challenges can affect customers. A member of the product service team, Marcus has more than two decades of experience working for Sandvik. He is focused on customer experience, specifically how to provide Sandvik customers with the right technical knowledge in the best way to get the best results.

SAF 2205™+ is generating lots of interest among customers eager to learn more about how it can benefit them. Marcus has shared some of the most frequently asked questions about SAF 2205™+ and his answers:

Q.1 What is SAF 2205™+?

We call it “Plus” because the latest member of our SAF 2205™ bar family is pre-engineered to comply with the toughest demands in the oil and gas industry. It is tested to withstand extreme corrosion and is certified to meet the latest subsea requirements, such as avoiding hard-to-detect pitting corrosion or other types of general corrosion in pumps and valves.

SAF 2205™+ is a duplex (austenitic-ferritic) stainless steel with excellent material cleanliness, making it a perfect choice for highly demanding applications. The alloy is our latest grade of stainless steel that focuses on meeting current and future end-user specifications.

Q.2 How is SAF 2205™+ different?

Not long ago, meeting ASTM, EN-norm, and NORSOK standards was the critical benchmark; however, times have changed, and requirements have become even stricter. The ever-increasing list of new standards and customer demands includes increased reduction ratio, tighter chemical specifications, and extra testing, just to name a few. In addition to meeting common oil and gas standards, our clients now face additional testing requirements to certify the material for aggressive conditions.

Unlike other stainless steels, SAF 2205™+ is pe-approved to the latest IOGP S-563 and ISO 17781 standards. For our clients in the oil and gas industry, this translates into a vital time saver because they won’t have to wait weeks to comply with new tests.

Q.3 What are the benefits and features of SAF 2205™+?

SAF 2205™+ is a super-clean material with enhanced pitting corrosion resistance, outstanding mechanical properties (up to 50% higher impact strength level than Sanmac® 2205), and better weldability. It features a reduced level of sulphur and phosphorous, with even tighter chemical tolerances. This means the bar is optimized to withstand corrosion further, and its chemical composition is better suited for aggressive subsea environments. It comes with the latest certification required for demanding oil and gas components, making this material pre-certified and ready to go.

All bars are PMI-tested and ink-marked to ensure full traceability. The 3.1 certificate provides all information on the material’s production and testing, giving customers full peace of mind.

Q.4 What feedback do you receive from existing customers?

The feedback has been positive, especially from our customers in the pump and valve business, connected to the oil and gas industry. They can see the benefit in SAF 2205™+ due to the extensive testing we have put into it. It complies with the new industry standards and surpasses them by including features such as a minimum 4:1 reduction ratio for all sizes and verifies the austinite spacing. These features are not required in the standards but can be found in many end-user specifications. Using SAF 2205™+ reduces the risk of upgrading material components and has the potential to decrease the lead-time for manufacturing. This is especially important as many orders of new pumps are one-offs and short-term.


Sandvik has served the oil and gas industry for more than 60 years. We’re always looking for ways to innovate, improve safety and boost productivity. ​​SAF 2205™+ is a super-clean material with enhanced pitting corrosion resistance, excellent mechanical properties, and better weldability.

The most common dimensional sizes will be stocked and ready to ship from our warehouse in Sandviken, Sweden. The grade is also available at selected distributors in the US and the rest of Europe, which means you will have a shorter lead time for sourcing materials.

I’m looking forward to interacting with more customers to help them find the right solution that can help them save time and money. SAF 2205™+ is one of the material solutions that they can potentially benefit from the most and I am excited to share my technical knowledge with them to get the best results.
