321 Stainless Steel Plate – Technical & Commercial Overview

  • Grade: 321 (UNS S32100 / EN 1.4541)
  • Classification: Titanium-Stabilized Austenitic Stainless Steel
  • Standards Met: ASTM A240, AMS 5510, EN 10088-2

Advantages of 321 Stainless Steel Plate:

  • Superior High-Temp Stability
    Titanium addition (min. 5x carbon content) prevents chromium carbide formation during prolonged exposure to 870–1500°F (465–815°C), ideal for cyclic thermal stress.

  • Enhanced Corrosion Performance
    Resists intergranular, pitting, and crevice corrosion in acidic, chloride, and high-sulfur environments (e.g., petrochemical, marine atmospheres).

  • Oxidation Resistance
    Forms a protective chromium oxide layer, maintaining integrity in oxidizing atmospheres up to 1650°F (900°C).


Technical Specifications:

  • Composition (Typical %):

    • Cr: 17.0–19.0 | Ni: 9.0–12.0 | C: ≤0.08 | Ti: ≥5×C | Mn: ≤2.0 | Si: ≤0.75 | P/S: ≤0.045

  • Physical Properties:

    • Density: 8.0 g/cm³ | Melting Point: 2550–2650°F (1400–1450°C)

    • Thermal Conductivity: 16.2 W/m·K (100°C) | CTE: 17.3 µm/m·K (20–100°C)

  • Mechanical Data (Annealed):

    • Tensile: 520–670 MPa | Yield: 205–310 MPa | Elongation: 40–50%

    • Hardness: 70–90 HRB | Impact Toughness (Charpy V): ≥100 J


Specialized Applications:

  • Energy Sector: Flue gas desulfurization systems, boiler casings, turbine liners.

  • Oil & Gas: Downhole instrumentation housings, valve components, pipeline expansion joints.

  • Industrial Furnaces: Radiant tubes, muffles, conveyor belts for heat-treating.

  • Medical Devices: Autoclave trays, surgical tooling (post-polishing).

  • Nuclear: Non-critical structural components in moderate radiation environments.


Form & Processing Guidelines:

  • Available Formats:

    • Thickness: 0.8–80 mm (hot-rolled) | 0.3–12 mm (cold-rolled)

    • Widths: 1500–2500 mm (coil/sheet) | Custom-cut blanks.

  • Machining Tips:

    • Use carbide tools with positive rake angles. Lubricate heavily for drilling/tapping.

    • Stress-relieve at 1050°F (565°C) post-heavy machining.

  • Welding:

    • Recommended methods: TIG, MIG, SAW with ER321/ER347 filler.

    • Avoid oxyacetylene welding to prevent Ti oxidation.


Surface Finishes & Treatments:

  • Standard Options:

    • Mill Finish (No. 1), 2B, BA, #4 Brushed, HL Hairline.

    • Bead-blasted or electropolished for ultra-clean surfaces.

  • Custom Solutions:

    • Aluminized coatings for extreme temp applications.

    • PTFE-impregnated surfaces for non-stick requirements.


Compliance & Traceability:

  • Certifications:

    • PED 2014/68/EU (Category II) | NACE MR0175 for sour service.

    • ISO 9001:2015, ISO 14001:2015 certified production.

  • Documentation:

    • 3.1/3.2 Material Certificates (EN 10204)

    • Full traceability via heat number, including Ti/C ratio verification.


Sustainability Profile:

  • 100% recyclable with no loss of properties.

  • Low-VOC production processes aligned with REACH regulations.


Why 321 Over 304/316?
While 304/316 excel in general-purpose use, 321 outperforms in thermal cycling and sensitization-prone environments. Its titanium stabilization eliminates post-weld annealing needs, reducing lifecycle costs in high-temp fabrication.


Ordering Notes:

  • MOQ: 500 kg (standard sizes) | Lead Time: 2–4 weeks.

  • Tolerance: ±5% on thickness (ASTM A480).

  • Global shipping with HS Code 7219.32.00 compliance.
