Alleima celebrates five years since launching Sanicro® 35 - alloy with superior corrosion resistance

Sanicro® 35 was launched five years ago and quickly became Alleima's most in-demand game-changer product. The product has been selected for its superior corrosion resistance in the most demanding environments, including chemical, bio, and petroleum refineries.

NASHVILLE, Tenn., April 4, 2025 /PRNewswire/ -- Alleima, a global manufacturer of high value-added products in advanced stainless steels and special alloys, launched the now highly sought after and field proven Sanicro® 35 grade in 2020 at The Association for Materials Protection and Performance (AMPP) Annual Conference and Expo in Texas, USA. Shortly after its global market introduction, one of the largest oil refiners on the Gulf Coast put it into service for two heat exchangers in their crude unit overhead, and the alloy proved its value of bridging the gap between stainless steels and nickel alloys. 

Since then, Alleima has delivered seamless tubes to the market securing millions in orders annually for different industries such as fertilizer production, chemical processing, and renewable feedstock pre-treatment. Most recently, one of the largest orders was signed with a repeat customer that has upgraded seven crude unit air coolers at a major refinery on the US Gulf Coast. In this application, Sanicro® 35 was selected for its superior corrosion resistance in ammonium chloride salts environment. This marks the first global reference in air cooler type heat exchangers. This year at AMPP, Alleima will be promoting the possibilities for renewable diesel production and the chemical process industry. 

When a large refinery on the US Gulf Coast chose to upgrade their crude overhead condensers to Sanicro 35®, Brask Inc, a leading manufacturer of tube & shell heat exchangers on the US Gulf Coast, became one of the first fabricators to work with the alloy. 

"We are very happy with the performance of Sanicro 35^® and the support we have received from Alleima. From our long-standing collaborative relationship with Sandvik Materials Technology, today known as Alleima, we were confident that we would be able to fabricate successfully with Sanicro 35^®, knowing we had the support of the Alleima technical marketing team behind us. Alleima provided us with important information such as the code case details, the welding procedure number, and input on filler metal selection, ensuring fabrication went entirely to plan. When the refinery requested expedited delivery, Alleima stepped up, working tirelessly to meet the new deadline, which resulted in us delivering the equipment on time for installation at the refinery," says Dinesh Bakshi, Vice President of Sales and Marketing at Brask.

"Our mission is to push metallurgical boundaries and provide high integrity solutions for safe operation in critical services all around the world. There are countless opportunities across various industries where we can assist our customers with their technical challenges. The demand for Sanicro® 35 has continued to rise since we first launched the product at AMPP five years ago. Attending this event once again is the perfect way to celebrate this milestone," says Carl von Schantz, President of the Tube division at Alleima.

Traditionally, engineers have used nickel-based Alloy 625 as the go-to grade for equipment in corrosive environments. However, its price is high and variable due to its alloying content, which includes 58 percent nickel and up to 10 percent molybdenum. Sanicro® 35 provides similar performance and can withstand a wide range of corrosive conditions, including seawater, acid and alkali, erosion-corrosion, pitting and crevice corrosion, and stress corrosion cracking (SCC).

Alleima will have several representatives from the company at AMPP with technical experts presenting.
