Comprehensive Overview of S32654 Stainless Steel Plate
1. Product Description
S32654 (commonly known as 654SMO) is a super-austenitic stainless steel characterized by ultra-high corrosion resistance, surpassing conventional austenitic grades (e.g., 316L) and even duplex steels. Its composition includes elevated chromium (23–25%), nickel (21–23%), molybdenum (7–8%), and nitrogen (0.45–0.55%), enabling performance comparable to nickel-based alloys like Inconel or Hastelloy in aggressive environments. Key advantages include:
-
Exceptional pitting/crevice corrosion resistance in chloride-rich media (e.g., seawater, acids)16.
-
High strength (yield strength ≥430 MPa) due to nitrogen enhancement, outperforming 254SMO and 904L38.
-
Excellent weldability and toughness across cryogenic to elevated temperatures69.

-
Customization: Cut-to-size plates, surface polishing (e.g., No. 4 finish), or specific coating upon request310.
5. Equivalent Grades
Global designations for S32654 include259:
-
UNS: S32654
-
EN: X1CrNiMoCuN24-22-8 (1.4652)
-
China: 015Cr24Ni22Mo8Mn3CuN (GB/T)
-
Japan: JIS-designated equivalents under development.
6. Applications
S32654 plates are critical in extreme corrosion environments:
-
Offshore/Marine: Seawater piping, heat exchangers, submarine components16.
-
Energy: Flue gas desulfurization (FGD) systems, desalination plants, nuclear wastewater handling310.
-
Chemical Processing: Reactors, scrubbers, and pipelines for acids/chlorides69.
-
Industrial: Bleaching equipment (pulp/paper), high-pressure RO systems, salt/酱油 brewing tanks48.
Why Choose S32654 Plates?
This alloy bridges the gap between standard stainless steels and costlier nickel alloys, offering >55 PRE (Pitting Resistance Equivalent) for longevity in critical infrastructure69. Its versatility in fabrication (welding, forming) and compliance with global standards make it ideal for engineers prioritizing safety and lifecycle cost.
