Instead of investing in costly nickel alloys for your heat exchanger tubing, why not choose a cost-efficient alternative? This is why leading producers with demanding process applications are increasingly opting for Sanicro® 35 to bridge the gap between standard duplex or austenitic grades and traditional nickel alloys.

Sanicro® 35 - the cost-effective alternative
Skip to content
Prevent deposit buildups
A few years ago, we developed this super-austenitic grade as a smart, effective way to avoid deposit buildup, pitting and stress corrosion cracking. Left unchecked, these issues can lead to plugging, loss of efficiency and potentially unscheduled maintenance. Today, having received positive industry response, we are selling this innovative tube on three continents.
The best of both worlds
With over 900 active alloy compositions in the Alleima portfolio, you might assume every need is covered. But we identified a gap for modern refineries exposed to a wide range of different temperatures and corrosive environments. There is often a tendency to default to Alloy 625 or C-276 for applications like recuperators, CDU overhead systems or REAC units. Until now!
Sanicro® 35 – a member of the Sanicro family
Sanicro is the trademark name for our family of high-alloy, multi-purpose stainless steels. As a member, Sanicro® 35 (UNS N08935) is a structurally stable, PRE 52 super-austenitic alloy that offers extreme localized corrosion resistance and outperforms conventional 6Mo grades, with only moderate nickel content.
What gaps will you fill?
The diagram below shows the target area for applications of Sanicro® 35. You may have ideas on where this could be put to work in aggressive corrosive conditions. Let’s talk.
How Sanicro® 35 compares to other grades
The tests below demonstrate how Sanicro® 35 delivers exceptional resistance to crevice corrosion and pitting when compared with alternative alloy options.
Sanicro® 35 has crevice corrosion resistance higher than Alloy 625 and at least on par with C-276.
Sanicro® 35 is designed to handle a significantly higher critical pitting temperature than standard grades. Note: 254 SMO is a trademark owned by Outokumpu OY.
