Product Specifications

Mechanical & Physical Properties

Tensile Strength

Our stainless steel plates exhibit a tensile strength range of 515–1035 MPa, ensuring exceptional resistance to deformation under load. This makes them ideal for structural components like stainless steel railroad tie plates and high-stress environments. The minimum yield strength of 205 MPa guarantees stability in applications requiring rigidity, such as stainless steel license plate screws and heavy machinery.

Bending Strength

With elongation rates exceeding 40%, our plates maintain integrity even under severe bending or forming processes. This ductility is critical for manufacturing complex shapes, including stainless steel plated brass fittings, without cracking or weakening.

Material Identification & Standards

Key Designations

• ASTM A240/A276: Specifies requirements for chromium and chromium-nickel stainless steel plates, bars, and shapes (Ni: 8–11%, Cr: 18–20%).
• JIS G4305: Japanese standard for cold-rolled SUS304 plates (C ≤0.08%, Mn ≤2.0%).
• GB/T 20878: Chinese standard 06Cr19Ni10, equivalent to ASTM 304.

Why Compliance Matters

Each standard ensures precise control over elements like carbon (≤0.08%), sulfur (≤0.03%), and nitrogen (≤0.10%) to optimize corrosion resistance and mechanical performance.

Weight Calculation

Calculate plate weight using the formula:
$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times 7.93$
Example: A 3 mm × 1.5 m × 3 m plate weighs:
$3\times 1.5\times 3\times 7.93=107.06\text{kg}$

Why Stainless Steel Corrodes?

Despite its resilience, stainless steel can rust under specific conditions:

1. Chloride Exposure: Coastal or de-icing environments accelerate pitting corrosion.
2. Mechanical Damage: Scratches or contamination (e.g., iron particles) disrupt the passive chromium oxide layer.
3. Improper Heat Treatment: Incorrect annealing reduces corrosion resistance.
