Sanicro 825 (UNS NO8825) extends the corporate’s rising Sanicro portfolio of nickel alloys and austenitic stainless steels for aggressive moist, corrosive and high-temperature, stress, acidic and seawater situations.
A high-strength alloy with minimal 40% nickel content material, Sanicro 825 has wonderful corrosion resistance to acids and alkalis, superior resistance to stress corrosion cracking (SCC) and good corrosion resistance to phosphoric, nitric, sulphuric and natural acids, seawater, caustic chloride alkalis and ammoniac media.
Secure, straightforward to machine and weld, the brand new alloy is right to be used in a variety of elements and installations together with warmth exchangers, evaporators, offshore piping programs, seawater coolant, valves and flanges. It serves a large number of industries together with oil and gasoline, chemical, petrochemical, pulp and paper, pickling gear, nuclear gas processing and meals processing.
Out there in three- to seven-meter lengths with an outdoors diameter (OD) starting from 20mm-260mm, Sanicro 825 affords a cheap various to superalloys akin to Alloy 625 and Alloy 718. Its chemical formulation has been tailor-made inside EN, UNS and ASTM requirements.
“Sanicro 825 opens new high-performance prospects for our prospects. At elevated temperatures and in corrosive situations, this new grade affords clear benefits to plain stainless-steel or duplex grades and is extra cost-efficient than some superalloys,” mentioned Martin Holmquist, enterprise improvement supervisor, Sandvik Supplies Expertise.
“Whereas we naturally adhere to all business requirements, Sanicro 825 isn’t any bizarre grade. At Sandvik, we try to set a ‘commonplace inside the usual’, which implies constantly adhering to even tighter tolerances on the chemical composition than these technically required. That is true for Sanicro 825, which we’ve additional tailor-made and optimized to seek out the candy spot for bar and hole bar,” mentioned Marcus Hillbom, technical advertising and marketing supervisor and gross sales, Sandvik Supplies Expertise.
