Premium Stainless Steel Metal Plate | 316L & 304L Dual Grades

Product Specifications

Key Properties

1. Tensile & Yield Strength

   • 316L: Offers tensile strength of 485–620 MPa (70,340–89,923 psi) and yield strength ≥205 MPa (29,740 psi). The addition of molybdenum (2–3%) enhances resistance to chloride-induced pitting, making it ideal for marine or chemical environments.
   • 304L: Provides tensile strength of 515–690 MPa (74,694–100,076 psi) with lower carbon content (≤0.03%), reducing intergranular corrosion risks during welding.

2. Bend Strength & Ductility

   • Both grades exhibit ≥40% elongation, enabling deep drawing and severe bending without cracking. 316L is preferred for complex shapes in architectural cladding, while 304L excels in food-grade applications due to its hygienic 2B finish.

3. Corrosion Resistance

   • Chromium (16–18% in 316L; 18–20% in 304L) forms a self-healing oxide layer. 316L outperforms in chloride-rich settings, while 304L resists organic acids in food processing.

Identification & Marking

• International Standards:
  • 316L: ASTM A240, EN 1.4404, JIS SUS316L.
  • 304L: ASTM A240, EN 1.4307, JIS SUS304L.
• Laser-etched codes include heat batch numbers, mill certifications (TISCO, Baosteel), and compliance with ISO 9001.

Weight Calculation

Use the formula:
$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times \text{Density (7.93 g/cm³)}$
Example: A 5 mm thick 316L plate (1.2m × 2.4m) weighs:
$5\times 1.2\times 2.4\times 7.93=114.5\text{kg}$.

Why Stainless Steel Rusts?

While stainless steel is corrosion-resistant, degradation occurs under specific conditions:

1. Chloride Exposure: Saltwater or de-icing agents penetrate the oxide layer, causing localized pitting.
2. Mechanical Damage: Scratches expose the iron matrix to oxygen, initiating rust.
3. Low Oxygen Environments: Stagnant water inhibits oxide regeneration, leading to crevice corrosion.
4. High-Temperature Oxidation: Prolonged exposure above 870°C degrades protective films.

Applications

• Custom Stainless Steel Plates: Tailored for architectural façades, industrial machinery, and stainless steel charger plates with No.4/HL finishes for aesthetic durability.
• Gold Plated Stainless Steel: Decorative items like jewelry or luxury tableware typically last 2–5 years with proper care, as gold layers (0.5–5µm) wear off under friction or chemical exposure.
