Key Features & Technical Insights
Tensile Strength
Tensile strength measures a material’s resistance to breaking under tension. For 304 grinding stainless steel sheet plate, the range of 515–1035 MPa ensures durability in high-stress applications like construction beams, chemical tanks, and automotive components. Cold-rolled variants exhibit higher strength due to work hardening, while hot-rolled plates prioritize formability.
Bending Strength
Bending strength correlates with tensile properties but focuses on deformation under load. Austenitic grades (e.g., 304) offer superior ductility, allowing bends up to 180° without cracking. Ferritic grades (e.g., 430) require careful handling to avoid brittleness. For gold plated stainless steel sheet, post-plating annealing ensures flexibility while maintaining surface integrity.
Identification Methods
Stainless steel grades are identified via:
- Chemical Analysis: Using XRF or spark testing to verify Cr (≥10.5%), Ni (8–10% for 304), and Mo (2–3% for 316).
- Magnetism: Austenitic grades (304/316) are generally non-magnetic; slight magnetism may occur after cold working.
- Surface Marking: Laser-etched labels (e.g., “ASTM A240”) or color-coded edges for quick recognition.
Weight Calculation Formula
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density (7.93 g/cm³)
Example: A 2mm × 1m × 2m china stainless steel plate sheet weighs:
2 × 1 × 2 × 7.93 = 31.72 kg.
Why Does Stainless Steel Rust?
Despite its corrosion resistance, stainless steel can rust under specific conditions:
- Chloride Exposure: Coastal environments or de-icing salts accelerate pitting corrosion, especially in 304 (vs. 316’s superior chloride resistance).
- Surface Contamination: Organic residues (food, grease) or iron particles from tools create localized galvanic cells, breaking the passive oxide layer.
- Mechanical Damage: Scratches or weld zones reduce chromium concentration, weakening corrosion protection.
- Improper Cleaning: Harsh abrasives or chlorine-based cleaners degrade surface finishes like mirror or gold plated stainless steel sheet.
