Alleima has received an important order for its Sanicro® 35, for overhead exchanger tubes in a crude upgrader facility in Canada. This marks the first order for Sanicro® 35 to be produced by the Alleima tube mill in Scranton, Pennsylvania, with raw materials melted and produced through Alleima’s integrated production system.
Alleima, a leading manufacturer of high value-added products in advanced stainless steels and special alloys as well as products for industrial heating, has secured an important order for its Sanicro® 35 (UNS N08935) PRE 52 super-austenitic alloy for overhead exchanger tubes in a crude upgrader facility in Canada.
This marks the first order for Sanicro® 35 to be produced by the Alleima tube mill in Scranton, Pennsylvania, which is an accomplishment that represents another milestone for the company’s flagship alloy.
Sanicro® 35, is an alloy combining the best features of a super austenitic stainless steel and a nickel alloy, designed for highly aggressive corrosive environment.
It will replace tubes made from the high-alloy duplex stainless steel SAF® 2707 HD, following the customer’s desire to extend the turnaround cycle. Sanicro® 35 was compared to UNS N06200, but it was ultimately selected for its strong performance and cost effectiveness. Sanicro® 35 performs similarly to C-276 and better than alloy 625. It can also be used in a higher temperature range than duplex grades.
“Through our experience of overhead exchangers, we were able to demonstrate to our customer that Sanicro® 35 was the ideal material for their replacement tubes and that UNS N06200 would be a much more costly and overly conservative grade for them to use,” says Karen Picker, Technical Marketing Manager – Tube Americas.
“By expanding our U.S. production capabilities, we can better serve the Americas region and the increased demand for higher alloyed materials. Sanicro® 35 is an advanced material that is helping move our customers forward, and interest in it is increasing. In a cost-conscious industry seeking to extend turnaround cycles, where lead times, material availability, and performance are driving decision making, recognition of Sanicro® 35 as a great solution is growing,” says Jennifer Svensson, Sales & Marketing Manager.
