To meet IMO (International Maritime Organization) regulations for reducing harmful sulfur oxide emissions, merchant vessels are required to have marine scrubber units installed in order to burn heavy fuel oil. High-performance materials are vital to withstanding the extremely corrosive conditions in a scrubber.
Corrosion resistance, optimized lifetime and sustainability
The operating conditions inside a marine scrubber are extremely aggressive due to a combination of acids, elevated temperatures and the high chloride content in the wash water. To tackle these hostile conditions and to guarantee a long service life for the scrubber, it’s essential to choose the right high-performance stainless steels. Stainless steels also contribute to sustainability as the system lasts longer, with no need for regular replacement of components. Choosing the correct stainless steel grades helps you save both energy and resources.
Benefits of using Outokumpu stainless steel for scrubbers
Our high performance materials offer the corrosion resistance and high mechanical strength required for marine scrubbers, at an affordable lifetime price.
Outokumpu is the world leader in using recycled material in the production of stainless steel, with an average of over 90% recycled content. Currently, Outokumpu also has the lowest carbon footprint in the global stainless steel industry.
High level of technical support:
Outokumpu is engaged in extensive R&D activities, including simulated laboratory testing and long-term field testing carried out in cooperation with scrubber manufacturers. We are at your service to support your selection of materials.
Discover our selection of stainless steel grades for scrubbers
Our key Ultra range grades for scrubbers: • Ultra 254 SMO • Ultra 654 SMO
The Ultra range includes highly-alloyed austenitic grades for extremely corrosive environments. The strength and elongation properties of the Ultra range are similar or better than conventional austenitic grades. Despite the greater strength of these steels, they form and weld nicely.
Our key Forta range grades for scrubbers: • Forta SDX 2507 • Forta DX 2205
Duplex (austenitic-ferritic) stainless steel combines many of the best properties of austenitic and ferritic stainless steels: high strength, good corrosion resistance and enhanced resistance to stress-corrosion cracking. The Forta range includes the strongest stainless steels in our portfolio.
