Performance Highlights
Tensile & Bending Strength
The 430 stainless steel sheet/plate delivers a tensile strength of ≥450 MPa, ensuring structural integrity in high-stress environments such as automotive exhaust systems and industrial machinery. Its ferritic microstructure provides excellent bending performance, with a minimum elongation of 20%, allowing seamless cold-forming into complex shapes like mufflers, heat shields, and architectural cladding. Cold-rolled variants (cold rolled stainless steel plate/sheet) exhibit enhanced surface uniformity and dimensional accuracy (±0.1 mm), critical for precision stamping and CNC machining.
Identification & Marking
Our sheets comply with global standards:
- ASTM A240 TP430: Identified by low carbon content (≤0.12% C) and chromium stabilization.
- EN 1.4016: Includes dual stabilization (Ti + Nb) for resistance to chloride-induced pitting.
- Laser-etched batch numbers and material grades ensure traceability and quality assurance.
Weight Calculation
Calculate plate weight using the formula:
Example: A 2 mm × 1219 mm × 2438 mm sheet weighs .
Corrosion Resistance & Rust Prevention
While 430 stainless steel sheet/plate offers cost-effective oxidation resistance, localized rust may occur under specific conditions:
- Chloride Exposure: Chloride ions (e.g., coastal or de-icing environments) can penetrate the chromium oxide layer, leading to pitting.
- Mechanical Damage: Scratches or abrasions expose the iron matrix to moisture, accelerating surface oxidation.
- High-Temperature Oxidation: Prolonged exposure above 850°C may degrade the passive film. For extreme conditions, pair with protective coatings or opt for austenitic grades like 316.
