Superior Stainless Steel Metal Plate | 2B/HL Finish & ASTM Certified

Product Specifications

Key Properties

Tensile Strength

Our stainless steel plates exhibit exceptional tensile strength, ranging from ≥515 MPa (304) to ≥520 MPa (316). The high nickel (8–12%) and chromium (18–20%) content ensures superior ductility, achieving ≥40% elongation, making them ideal for deep-drawn applications like stainless steel plates and cups. The 316L variant, with added molybdenum (2–3%), resists pitting in chloride-rich environments, such as marine or chemical processing.

Bending Strength

Optimized for cold-forming, these plates withstand tight-radius bends (up to 180°) without cracking. The strain hardening exponent (n-value) of 0.32–0.45 ensures uniform deformation, critical for precision components. Post-welding, the heat-affected zone retains ≥90% of the base metal’s strength, essential for structural integrity.

Identification & Weight Calculation

Marking Methods

• Laser Etching: Permanent grade identification (e.g., "304," "316L") on plate edges.
• QR Codes: Traceability linked to batch-specific certifications from stainless steel plate manufacturer partners.
• Color Coding: Optional oxide tints (e.g., gold, bronze) for decorative alignment with architectural designs.

Weight Formula

$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times \text{Density (g/cm³)}$
Example: A 3 mm × 1.2 m × 2.4 m 304 plate weighs 3 × 1.2 × 2.4 × 7.93 = 68.6 kg.

Why Stainless Steel May Corrode?

Despite its corrosion resistance, stainless steel can rust under specific conditions:

1. Chloride Exposure: Prolonged contact with seawater or de-icing salts may cause pitting. Grades like 316L mitigate this with molybdenum.
2. Mechanical Damage: Scratches or grinding disrupt the passive chromium oxide layer. Our 2B/HL finishes minimize defects through controlled rolling and polishing.
3. Galvanic Corrosion: Contact with carbon steel or copper alloys in humid environments. Use insulating gaskets in mixed-metal assemblies.
4. High-Temperature Oxidation: Continuous exposure above 870°C degrades chromium’s protective oxide. Ceramic coatings are recommended for extreme heat.
