Chemical Composition

JIS G4305 SUS315J2 Cold-Rolled Stainless Steel Plate boasts a carefully balanced alloy composition that ensures superior performance. The primary elements include:

· Chromium (Cr): 16-18% (or 19.00-22.00% as per certain specifications), which forms a protective oxide layer, enhancing corrosion resistance.

· Nickel (Ni): 10-14% (or 4.50-6.50% as per specific standards), enhancing resistance to pitting and crevice corrosion, as well as improving ductility.

· Molybdenum (Mo): 2-3%, further enhancing corrosion resistance, particularly against chlorides and acids.

· Manganese (Mn): Up to 2% (or 1.00-2.00% as per specific standards), aiding in hot and cold workability.

Additional elements include Silicon (Si) ≤ 1.00%, Phosphorus (P) ≤ 0.040%, Sulfur (S) ≤ 0.030%, and Titanium (Ti) ≤ 0.040%, all contributing to the plate's overall performance.

Mechanical Properties

The SUS315J2 plate exhibits impressive mechanical properties, suitable for demanding applications:

· Tensile Strength: ≥520 MPa

· Yield Strength: ≥205 MPa

· Elongation: ≥40%

· Hardness: ≤201HB (or ≤187 HBW as per some specifications)

· Impact Toughness: ≥60 J (indicating good resistance to fracture under dynamic loading)

Heat Treatment State

TJC Steel Group's SUS315J2 Cold-Rolled Stainless Steel Plate is supplied in various heat-treated conditions, including annealing and solution annealing, to ensure optimal mechanical properties and corrosion resistance. These treatments eliminate internal stresses, refine the grain structure, and improve workability.
