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.
