Stainless Steel Plates | ASTM-Certified 316 Grade | Factory Direct

Premium Stainless Steel Plates | ASTM-Certified 316 Grade | Factory Direct

Product Overview

Engineered for industrial excellence, our stainless steel plates combine superior corrosion resistance, unmatched durability, and compliance with ASTM A240/AISI 316 standards. Designed for heavy-duty applications like stainless steel railroad tie plate systems, chemical processing, and marine environments, these plates are cold-rolled or hot-rolled to meet precise specifications. With factory-direct pricing and global certifications, we deliver reliability for infrastructure, construction, and high-temperature projects.

Technical Specifications

Key Properties

1. Tensile Strength

316 stainless steel plates exhibit a tensile strength of ≥515 MPa, ensuring structural integrity under extreme loads. The addition of molybdenum (2-3%) enhances resistance to pitting and crevice corrosion, making it ideal for chloride-rich environments like coastal railways or chemical plants.

2. Bend Strength

With a minimum yield strength of 205 MPa, these plates withstand bending angles up to 180° without cracking. Cold-rolled variants achieve higher bend ductility, suitable for forming complex shapes in stainless steel railroad tie plate fabrication.

3. Weight Calculation

Calculate plate weight using:
Weight (kg)=Length (m)×Width (m)×Thickness (mm)×7.93(Density, g/cm3)
Example: A 4x8 FT (1.22x2.44m), 8mm plate weighs:
$1.22\times 2.44\times 8\times 7.93=191.5\text{kg}$

4. Identification Marking

Each plate is laser-etched with:

• Material Grade (316/316L)
• ASTM Certification Code
• Batch Number & Manufacturer’s Logo

5. Why Stainless Steel Rusts

While 316 stainless steel plates resist oxidation, rust may occur under:

• Chloride Exposure: Coastal or de-icing salt environments accelerate pitting corrosion by breaking the chromium oxide layer.
• Mechanical Damage: Scratches from carbon steel tools create localized galvanic corrosion.
• High-Temperature Oxidation: Prolonged exposure above 800°C depletes chromium content, reducing corrosion resistance.
  Prevention: Regular passivation treatments and avoiding contact with incompatible metals.

Applications

• Rail Infrastructure: Stainless steel railroad tie plate systems for bridges, tunnels, and heavy-load tracks.
• Chemical Processing: Reactors, pipelines, and storage tanks resistant to acids/alkalis.
• Architectural: Structural cladding, elevators, and coastal building supports using 316 stainless steel plate.
• Marine: Ship components, offshore platforms, and desalination plants.
