In a bustling desalination plant off India's coast, engineers faced relentless pitting corrosion eating through 904L stainless foil liners in high-pressure RO membranes, threatening multi-million downtime. The solution? Switching to Alloy 926 Foil (UNS N08926, ASTM B625) a super-austenitic powerhouse with PREN 43+ that halted failures, extended service life by 3x, and slashed maintenance costs for procurement heads and OEMs.

Alloy 926 foil, also known as Cronifer 1925 hMo (Werkstoff 1.4529), bridges the gap between costly nickel alloys and standard austenitics, delivering unmatched resistance to chloride pitting, crevice corrosion, and stress cracking in sulfuric/phosphoric acids, brine, and sour gas—environments where 904L or 316L fail prematurely. With 6-7% Mo, 24-26% Ni, and nitrogen stabilization, its high PREN (≈42–45) ensures superior performance in hot brine, outperforming Alloy 926 vs 904L foil comparisons for pitting resistance.
Tailored for chemical processing units, offshore oil & gas instrumentation, marine pump seals, pharma reactors, and power FGD systems, these thin gauge foils (0.1mm to 0.5mm) form gaskets, liners, shims, and bipolar plates. Aurico Alloys LLP, a trusted Alloy 926 foil supplier in Mumbai, provides affordable, authentic stock from India to abroad, with EN 10204 3.1 MTC for NACE MR0175 sour service compliance.
As Alloy 926 shim stock manufacturer in Mumbai, we support hardware stores and fabricators with custom slit-to-size Cronifer 1925 hMo foil coils for stamping, ensuring precision for high-molybdenum needs in evaporation plants and hydrogen electrolyzers. Procurement teams gain from verified Alloy 926 foil stockholders in Maharashtra offering ASTM B625 UNS N08926 foil at competitive price per kg in India.
