Premium Stainless Steel Rail Tie Plate | 8mm 301/321 ASTM-Certified

Premium Stainless Steel Rail Tie Plate | 8mm 301/321 ASTM-Certified

Product Overview

Engineered for durability and precision, our stainless steel rail tie plate is designed to meet the rigorous demands of railway infrastructure. Manufactured from 301/321 stainless steel and certified under ASTM standards, this plate ensures exceptional corrosion resistance, high strength, and longevity even in harsh environments. Ideal for rail fastening systems, it guarantees stability and safety while reducing maintenance costs.

Technical Specifications

Key Properties

1. Tensile Strength

The 301 stainless steel rail tie plate offers a tensile strength of ≥515 MPa, while 321 stainless steel provides ≥485 MPa. This ensures resistance to deformation under heavy loads, making it suitable for high-stress applications like railway tracks.

2. Bend Strength

Both grades exhibit excellent bend ductility. 301 stainless steel can withstand a bend angle of 180° without cracking due to its work-hardening properties, whereas 321 stainless steel maintains integrity up to 150° under elevated temperatures.

3. Weight Calculation

Weight per plate is calculated using the formula:
Weight (kg)=Length (m)×Width (m)×Thickness (mm)×7.93(Density of stainless steel, g/cm3)
For standard dimensions:
$1.5\times 0.2\times 8\times 7.93=19.03\text{kg}$

4. Identification Marking

Each plate is laser-etched with:

• Material grade (301 or 321)
• ASTM certification
• Batch number
• Manufacturer’s logo

Why Stainless Steel Corrodes?

While stainless steel is highly corrosion-resistant, certain conditions can lead to rust:

• Electrochemical Corrosion: Exposure to saline environments (e.g., coastal railways) creates micro-batteries between contaminants and the steel surface, accelerating oxidation.
• Chemical Exposure: Acidic or alkaline substances (e.g., industrial pollutants) degrade the chromium oxide layer, allowing oxygen penetration.
• Mechanical Damage: Scratches or abrasions from improper handling compromise the protective layer, leading to localized rust.

Preventive Measures:

• Regular cleaning with pH-neutral detergents.
• Avoid contact with carbon steel tools to prevent galvanic corrosion.
• Apply passivation treatments to restore the chromium oxide layer.

Applications

• Railway Infrastructure: Secure rail-to-tie fastening with stainless steel wall plates for bridges and tunnels.
• Architectural: Compatible with 304 stainless steel plate for structural supports in coastal buildings.
• Industrial: Used in chemical plants and food processing units due to hygienic, non-reactive properties.
