This is Sanicro® 35 bar

At 30 °C (86 °F) in natural seawater, Sanicro® 35 bar delivers corrosion performance at least on par with Alloy 625 Grade 1. For dimensions above 4 inches, both materials meet the minimum yield strength requirement of 350 MPa (50 Ksi). Sanicro® 35 provides a more cost efficient and lower carbon alternative then Alloy 625, thanks to its optimized nickel content and non remelted production route. In addition, Sanicro® 35 exhibits substantially higher impact strength.

Both Sanicro® 35 and Alloy C-276 offer exceptional corrosion resistance across challenging chloride rich and aggressive environments. Sanicro® 35 combines this resilience with higher mechanical strength and superior machinability - providing a robust and cost-efficient alternative with optimized alloy content. Alloy C-276 remains a benchmark for extreme pitting resistance, but Sanicro® 35 brings a powerful balance of performance, durability, and value.

Sanicro® 35 delivers a step change in performance compared to 254SMO (6Mo), offering markedly higher crevice and pitting corrosion resistance together with stronger mechanical properties. While both grades provide robust corrosion protection, 254SMO stands out with slightly better machinability, whereas Sanicro® 35 delivers superior overall performance in critical applications.

Sanicro® 35-HS delivers excellent crevice corrosion resistance and is virtually immune to HISC (Hydrogen Induced Stress Cracking). In contrast, Alloy 718, as a precipitation hardened nickel alloy, is well documented to suffer from HISC in wet, chloride containing environments such as natural seawater. As a result, Sanicro® 35-HS exceeds the performance of Alloy 718 in wet corrosion applications, while maintaining comparable strength levels.

Alloy 716/725 has demonstrated a similar susceptibility to HISC (Hydrogen Induced Stress Cracking) as Alloy 718, reinforcing Sanicro® 35-HS as a strong and reliable alternative in applications where hydrogen related cracking must be tightly controlled. With its lower total alloying content, Sanicro® 35-HS also provides a more cost efficient solution with a reduced carbon footprint, without compromising performance.

Sanicro® 35-HS provides outstanding resistance to Hydrogen Induced Stress Cracking (HISC), as well as crevice and pitting corrosion in chloride rich environments, delivering a higher overall pitting resistance equivalence (PRE) then Alloy 925. Sanicro® 35-HS has a slightly higher tensile strength than that of Alloy 925 but Sanicro® 35-HS further differentiates itself through superior flexibility and its ability to undergo extensive cold working to achieve targeted tensile properties. Both grades offer the same level of machinability.
