321 Stainless Steel Plate – Technical & Commercial Overview
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).
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
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.
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.
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.
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.
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.
