Precision Stainless Steel Metal Plate | 316L Sheets & 2B Polish

Product Specifications

Key Properties

Tensile Strength

316L stainless steel sheets deliver a tensile strength of ≥480 MPa and yield strength of ≥175 MPa, ensuring exceptional structural integrity for heavy-load applications like stainless steel floor plate systems. The low carbon content (≤0.03%) minimizes carbide precipitation during welding, maintaining corrosion resistance in chloride-rich environments. Compared to standard 316 steel, 316L achieves 15% higher elongation (≥40%), making it ideal for deep-drawn components such as stainless steel decora cover plate designs.

Bending Strength

The material’s excellent ductility allows tight-radius bends (up to 180°) without cracking. With a strain hardening exponent (n-value) of 0.35–0.45, 316L retains ≥90% of its original strength post-forming. This property is critical for stainless steel decora plate installations requiring intricate shapes. Cold-rolled sheets also exhibit superior flatness (±0.1 mm/m), essential for precision architectural cladding.

Identification & Weight Calculation

Marking Methods

• Laser Etching: Permanent UNS S31603 grade markings on edges for traceability.
• QR Codes: Embedded digital tags linking to batch-specific certifications and chemical reports.
• Color Coding: Optional oxide tints (e.g., gold, bronze) to match stainless steel decora cover plate aesthetics.

Weight Formula

$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times 7.98(\text{Density})$
Example: A 4 mm × 1.5 m × 3 m stainless steel floor plate weighs 4 × 1.5 × 3 × 7.98 = 143.64 kg.

Why Stainless Steel May Corrode?

While 316L offers superior corrosion resistance, specific conditions can trigger rust:

1. Chloride Exposure: Prolonged contact with seawater or de-icing salts may cause pitting. However, 316L’s molybdenum content (2–3%) provides 50% higher pitting resistance than 304 steel.
2. Mechanical Damage: Abrasions or improper grinding can disrupt the chromium oxide layer. Our 2B polish reduces surface defects through controlled cold-rolling.
3. Galvanic Corrosion: Contact with carbon steel or copper alloys in humid environments. Isolate materials using non-conductive gaskets in stainless steel decora plate assemblies.
4. High-Temperature Oxidation: Continuous exposure above 870°C degrades protective oxides. For extreme heat, use ceramic-coated alternatives.
