Durable Stainless Steel Metal Plate | HL Finish & Corrosion-Resistant Industrial-Grade Solutions

Technical Specifications

Mechanical & Physical Properties

Tensile Strength

The stainless steel 304 plate offers exceptional tensile strength, making it ideal for structural and industrial applications.

• 304 Grade: Minimum 520 MPa (75,000 psi), ensuring resistance to deformation under heavy loads.
• 316L Grade: Minimum 620 MPa (90,000 psi), enhanced by molybdenum for chloride-rich environments.
  These properties make it suitable for pressure vessels, marine hardware, and architectural frameworks.

Bending Strength

Austenitic stainless steel’s high ductility allows seamless bending without cracking:

• Cold-Rolled Plates (0.5–3mm): Achieve bending radii of 1–2× thickness.
• Hot-Rolled Plates (≥4mm): Require 3–4× thickness for safe forming.
  This flexibility supports complex designs in stainless steel barbecue plates and machinery components.

Identification & Marking

Grades are laser-etched or stamped for traceability:

• 304: UNS S30400 / AISI 304 / EN 1.4301
• 316L: UNS S31603 / AISI 316L / EN 1.4404
  Mill Test Reports (MTRs) validate chemical composition (e.g., 18% Cr, 8% Ni for 304) and compliance with ASTM/EN standards.

Weight Calculation Formula

Calculate plate weight using:
Weight (kg)=Thickness (mm)×Width (m)×Length (m)×7.93(Density of SS, g/cm3)
Example: A 3mm × 1.5m × 6m 304 plate weighs:
$3\times 1.5\times 6\times 7.93=214.11\text{kg}$
This formula ensures accurate logistics planning for stainless steel base plate projects.

Why Does Stainless Steel Rust?

While stainless steel resists corrosion, specific conditions can cause rust:

1. Low Chromium Content: Grades with <10.5% Cr fail to form a stable passive oxide layer.
2. Chloride Exposure: Coastal or industrial environments accelerate pitting in 304; 316L’s 2-3% Mo mitigates this.
3. Poor Fabrication: Substandard welding or grinding disrupts the protective chromium oxide layer.
4. Chemical Contamination: Residual iron particles from tools trigger galvanic corrosion.
5. High-Temperature Oxidation: Prolonged exposure above 800°C degrades 304’s corrosion resistance.
