Sanicro® 35 - the cost-effective alternative

Sanicro® 35 is a more robust alloy than other austenitic or super-austenitic steel grades, offering an alternative to nickel alloys. It’s ideal for refineries with CDU overheads, REACS, gas cleaning, sour water, petrochemicals and chemical plants (handling chlorinated hydrocarbons, PTA, inorganic acids, organic acids), seawater-cooled heat exchangers, biofuels, and renewable applications. It provides excellent price performance, balancing performance fluctuations and minimizing risk, ultimately extending the production lifecycle.

When it comes to welding, Sanicro® 35 offers significant advantages by requiring no pre-heating or post-weld heat treatment. This feature streamlines the welding process and helps reduce overall fabrication time and costs. Its high structural stability ensures that even during welding, the material remains robust and resistant to the formation of unwanted intermetallic phases. Beyond welding, Sanicro 35 stands out for its exceptional formability. The grade’s outstanding ductility allows for cold bending to tight radius, making it ideal for complex designs.

Sanicro® 35 offers hydraulic and instrumentation (H&I) distributors a cost-effective alternative by replacing several specialized tube grades and freeing tied-up capital. Its versatility, stability and ease of handling for leak-free fittings allow it to substitute for 6Mo alloys, Alloy 825, and Alloy 625. It is ideal for chemical, petrochemical and coastal plants with high chloride content, as well as for wellhead panels, X-mas trees, renewable energy, and elevated temperature exposure to chlorides and acids.

Due to the popularity of Sanicro 35 in tube format, we’ve introduced round bar and seamless pipe in our standard range of 20 to 240 mm outer diameters. Bar is, of course, ideal for manufacturing of flanges, valves and discs, fittings, couplings, rings and seals, bolts and nuts, shafts, drilling tools and heat exchanger parts. Please note that bars are supplied to production order only.
