Trusted Stainless Steel Metal Plate | 304L Grade for Demanding Chemical Applications

Technical Specifications

Mechanical & Physical Properties

Tensile Strength

The 304L stainless steel plate delivers robust tensile strength, making it ideal for high-stress chemical environments.

• Minimum Tensile Strength: 485 MPa (70,300 psi)
• Yield Strength: 170 MPa (24,700 psi)
  This ensures structural integrity in pressure vessels, reactor tanks, and piping systems exposed to corrosive media like acids, alkalis, and chlorides.

Bending Strength

With exceptional ductility, 304L plates can be bent to complex shapes without cracking:

• Cold-Rolled Plates (0.5–3mm): Achieve bending radii of 1–2× thickness.
• Hot-Rolled Plates (≥4mm): Bend radii of 3–4× thickness for safe forming.
  This flexibility supports applications like stainless steel kick plates commercial and custom-designed chemical equipment.

Identification & Marking

Grades are laser-etched or stamped for traceability:

• 304L: UNS S30403 / ASTM A240 / EN 1.4307
  Mill Test Reports (MTRs) validate compliance with international standards, including chemical composition (e.g., 18–20% Cr, 8–12% Ni, ≤0.03% C) and mechanical properties.

Weight Calculation Formula

Calculate plate weight using:
Weight (kg)=Thickness (mm)×Width (m)×Length (m)×7.93(Density of SS, g/cm3)
Example: A 5mm × 1.2m × 3m 304L plate weighs:
$5\times 1.2\times 3\times 7.93=142.74\text{kg}$
This formula ensures precise logistics planning for large-scale projects like stainless steel pie plate manufacturing.

Why Does Stainless Steel Rust?

While 304L resists corrosion, specific conditions can compromise its integrity:

1. Chloride Exposure: Prolonged contact with saltwater or chloride-rich chemicals (e.g., HCl) may cause pitting. 304L’s low carbon content reduces but does not eliminate this risk.
2. Intergranular Corrosion: Poor welding practices without post-weld annealing can deplete chromium near grain boundaries, weakening the passive oxide layer.
3. Mechanical Damage: Scratches or abrasions expose the base metal to oxidation, especially in acidic environments.
4. High-Temperature Oxidation: Sustained exposure above 800°C degrades chromium oxide stability, necessitating higher-grade alloys like 316L.

Applications & Customization

• Chemical Processing: Reactor tanks, heat exchangers, and pipelines handling sulfuric acid, nitric acid, and solvents.
• Food & Beverage: Stainless steel pie plate molds, fermentation tanks, and hygienic conveyor systems.
• Commercial Equipment: Stainless steel griddle plate for gas grill surfaces, stainless steel kick plates commercial for industrial kitchens, and architectural cladding.
• Pharmaceuticals: Sterilization equipment and drug storage containers requiring non-reactive surfaces.
