254SMO is a high-performance super austenitic stainless steel known for its exceptional corrosion resistance, especially in harsh environments containing chloride ions, acids, and high temperatures. It belongs to the family of molybdenum (Mo)- and nitrogen (N)-alloyed stainless steels, designed to outperform conventional 316L or 317L in aggressive conditions.
2. Key Parameters
Chemical Composition (wt%):
Carbon (C) ≤ 0.03%
Manganese (Mn) ≤ 1.0%
Silicon (Si) ≤ 0.8%
Phosphorus (P) ≤ 0.03%
Sulfur (S) ≤ 0.01%
Chromium (Cr) 19.5–20.5%
Nickel (Ni) 17.5–18.5%
Molybdenum (Mo) 6.0–6.5%
Nitrogen (N) 0.18–0.22%
Copper (Cu) 0.5–1.0%
Mechanical Properties (annealed condition):
Tensile Strength: ≥ 650 MPa
Yield Strength (0.2% offset): ≥ 300 MPa
Elongation: ≥ 40%
Hardness: ≤ 220 HB
3. Standards
254SMO is manufactured and tested according to international standards, including but not limited to:
ASTM A240 / A240M (Plate, sheet, and strip for pressure vessels)
ASTM A480 / A480M (General requirements for flat-rolled stainless steel)
EN 10088-2 (European standard for stainless steel sheet/plate)
ASME SA-240 (For pressure vessel applications)
4. Equivalent (Equivalent Grades)
254SMO is known by different designations worldwide, depending on regional standards:
UNS S31254 (USA)
EN 1.4547 (European Union)
DIN X1NiCrMoCuN20-18-7 (Germany)
JIS SUS 254SMO (Japan, non-official but widely recognized)
5. Applications
Due to its superior corrosion resistance and mechanical strength, 254SMO is widely used in:
Marine and offshore engineering: Components exposed to seawater, such as offshore platforms, ship hulls, and desalination plants.
Chemical processing: Reactors, pipelines, and tanks handling acids (e.g., sulfuric acid, phosphoric acid) and chloride-rich solutions.
Pollution control: Flue gas desulfurization (FGD) systems in power plants, where resistance to sulfuric acid is critical.
Oil and gas industry: Downhole equipment, valves, and pipelines in high-salinity or acidic reservoirs.
Pulp and paper industry: Machinery in bleaching processes, which involve chlorine-based chemicals.
6. Laser Cutting of 254SMO Stainless Steel Plate
Laser cutting is a preferred method for processing 254SMO due to its precision and efficiency.
Advantages:
High precision: Narrow kerf width (typically 0.1–0.3 mm) and tight tolerances (±0.05 mm), ideal for complex shapes or intricate designs.
No material deformation: Low heat-affected zone (HAZ) minimizes warping or changes in material properties, preserving 254SMO’s corrosion resistance.
Versatility: Compatible with various sheet thicknesses and capable of cutting complex patterns (holes, curves, or custom geometries) without tool wear.
Efficiency: Faster processing compared to mechanical cutting for small to medium batches, with high automation potential.
Processing Range:
Thickness: Typically 0.5 mm to 20 mm (thicker plates up to 50 mm can be cut with high-power lasers, though speed may decrease).
Sheet size: Standard sizes (e.g., 1220×2440 mm, 1500×3000 mm) or custom dimensions.
Cutting types: 2D cutting (flat sheets) for profiles, holes, slots, or intricate designs used in industrial components, brackets, or structural parts.
