Sandvik’s Sanicro 825 Offer High-performance Possibilities

Sandviken, Sweden – Sandvik Materials Technology (part of Sandvik Group), a developer and producer of advanced stainless steels, special alloys, titanium, and other high-performance materials, has introduced Sanicro^® 825 (UNS NO8825), the company’s first-ever nickel-iron-chromium alloy in bar and hollow bar, for improved performance in corrosive, high-temperature environments. The new product expands the company’s growing Sanicro^® range of nickel alloys and austenitic stainless steels for aggressive wet, corrosive and high-temperature, pressure, acidic and seawater conditions.

It is a high-strength alloy with a minimum of 40 percent nickel content that has outstanding corrosion resistance to acids and alkalis, superior resistance to stress corrosion cracking (SCC), and good corrosion resistance to phosphoric, nitric, sulfuric, and organic acids, seawater, caustic chloride alkalis, and ammoniac media. The new alloy is stable and easy to machine and weld, ideal for use in a variety of components and installations such as heat exchangers, evaporators, offshore piping systems, seawater coolant, valves, and flanges.

It is available in lengths ranging from 3 - 7meter and has an outside diameter (OD) ranging from 20 - 260mm, making it a cost-effective alternative to superalloys such as Alloy 625 and Alloy 718. Its chemical composition has been adapted to EN, UNS, and ASTM requirements.

Martin Holmquist, Business Development Manager, Sandvik Materials Technology, said, “Sanicro^® 825 opens new high-performance possibilities for our customers. At elevated temperatures and in corrosive conditions, this new grade offers clear advantages to standard stainless steel or duplex grades and is more cost-efficient than some superalloys.”

Explaining Sanicro^® 825 as no ordinary grade, Marcus Hillbom, Technical Marketing Manager & Sales, Sandvik Materials Technology, added, “At Sandvik, we strive to set a ‘standard within the standard’, which means consistently adhering to even tighter tolerances on the chemical composition than those technically required. This is true for Sanicro® 825, which we’ve further tailored and optimized to find the sweet spot for bar and hollow bar.”

Elaborating on company’s extensive experience, Henrik Zettergren, Global Product Manager, Sandvik Materials Technology, asserted, “With a long tradition in R&D for some of the most demanding industries around the world, Sanicro^® 825 builds on Sandvik’s 60-year legacy of making premium, high-alloy Sanicro® for corrosive and high-temperature environments.”
