321 Stainless Steel Sheet

Durable 321 stainless steel sheet with excellent corrosion resistance and high-temperature strength, ideal for industrial and architectural applications. Its precision finish ensures reliable performance in demanding environments.

Description

321 Stainless Steel Sheet
A high-performance austenitic stainless steel sheet engineered for exceptional corrosion resistance, high-temperature stability, and durability. Ideal for demanding industrial, chemical, and architectural applications.

Key Features

  • Premium Material: 321 stainless steel (UNS S32100) with titanium stabilization (Ti content ≥5×C%) to prevent carbide precipitation and intergranular corrosion.
  • Superior Corrosion Resistance: Resists oxidation and corrosion in acidic, chloride-rich, and high-temperature environments (up to 800°C/1472°F).
  • Enhanced Mechanical Properties: High tensile strength (≥515 MPa) and yield strength (≥205 MPa) for structural reliability.
  • Versatile Surface Finishes: Available in 2B (cold-rolled, annealed, pickled), BA (bright annealed), No. 4 (brushed), and mirror finishes.
  • Precision Dimensions: Thickness range 0.3mm–6.0mm, standard widths of 1000mm/1219mm/1500mm, and custom lengths up to 6000mm.
  • Formability & Weldability: Excellent ductility for bending, stamping, and welding without compromising integrity.

Specifications

  • Grade: ASTM A240/A480, EN 10088-2, JIS G4304
  • Thickness Tolerance: ±0.02mm (strictly controlled)
  • Hardness: ≤95 HRB (annealed condition)
  • Density: 8.0 g/cm³
  • Applications: Heat exchangers, furnace components, chemical processing equipment, aerospace parts, and architectural cladding.

Customization Options

  • Tailored thickness, width, and length to meet project-specific requirements.
  • Specialized edge treatments (slit, sheared, or deburred).
  • Additional processing: laser cutting, perforation, or embossing.
