Selecting the right materials for biorefineries can improve equipment efficiency, production profitability, and safety.
The production of renewable diesel and sustainable aviation fuel (SAF) carries risks such as corrosion, cracks, or leaks due to aggressive conditions in the hydroprocessing plant. This can cause unscheduled maintenance and, if left unaddressed, potential safety risks
Advanced Materials Technology
Whether it is HEFA/ HVO (hydroprocessed esters & fatty acids) or Fisher Tropsch, alcohol to jet (AtJ), or synthetic fuel (CO2 to liquid fuel) we’re passionate about utilizing the strength of our 160-year Swedish heritage, expertise, and broad portfolio of over 900 active alloys to help advance the biofuels industry.
We identify and provide the most appropriate corrosion-resistant materials for various types of applications, like heat exchangers for hydroprocessing plants. Our product portfolio covers all tubular heat exchangers – feed/effluent, reactor effluent air cooler (REAC) water coolers, and sour water reboilers – for all hydroprocessing steps.

Sanicro® 35: bridging the gap for biofuels
Sanicro® 35 (UNS: NO8935) is a breakthrough alloy that bridges the gaps between standard stainless steel and nickel alloys. It’s a cost-effective answer to severe corrosion in a wide range of service conditions. Depending on the operating environment, it can be an alternative to more expensive nickel alloys 625, or even C-276.
Feed/effluent heat exchangers have traditionally used stainless steel grades TP321 or TP347 for tubing in both fossil-based and renewable feedstock plants. However, these grades are prone to stress corrosion cracking if chloride salt deposits are formed. Solving these issues has traditionally led to over-conservatism in materials selection and the over-specification of expensive nickel-based alloys such as Alloy 625 and the even higher alloyed C-276.
Sanicro→ 35 offers an effective alternative to nickel-based alloys. As well as having similar pitting corrosion resistance as alloy 625, Sanicro→ 35 has better crevice corrosion resistance. Sanicro® 35 also has excellent resistance to stress corrosion cracking in chloride environments.
Sanicro® 35 is already proving cost-efficiencies compared to nickel-based alloys, enabling large financial savings when building new hydroprocessing units or upgrading existing ones.
