Key Properties & Performance
Tensile and Bending Strength
The stainless steel sheet in 310S grade achieves a tensile strength of ≥520 MPa, while 309S plates maintain ≥485 MPa, ensuring resistance to deformation under extreme loads. This is critical for applications like furnace baffles and heat exchangers, where mechanical stress is constant. Bending strength is enhanced through cold-rolled processing, allowing sheets to withstand repeated flexing without cracking—ideal for sheet stainless steel Home Depot-ready fabrication projects.

Rust Prevention & Causes
Although stainless steel sheet is corrosion-resistant, rust may occur due to:
- Chloride Exposure: Prolonged contact with salt or acidic substances degrades the chromium oxide layer.
- Mechanical Damage: Scratches from abrasive tools expose the base metal to oxidation.
- Low Oxygen Environments: Stagnant moisture inhibits the self-repairing passive layer.
- Improper Welding: Carbon contamination during welding causes intergranular corrosion.
Manufacturing & Identification
Production Process
- Cold Rolling: Raw 310S/309S coils are precision-rolled to meet 1–6mm thickness specifications.
- Solution Annealing: Heat-treated at 1030–1180°C to restore ductility and corrosion resistance.
- Surface Treatment: Electrolytic polishing or perforation for stainless steel perforated sheet designs.
- Laser Marking: Each sheet includes grade (310S/309S), thickness, heat number, and compliance marks.
Applications
- Aerospace: Engine components and exhaust systems.
- Chemical Processing: Reactors and heat exchangers.
- Architecture: Sheet stainless steel Home Depot-compatible cladding and decorative panels.
