Different from hot rolled plate, our 304 stainless steel sheet adopts cold rolling process after pickling and precise rolling control:

1. Higher dimensional accuracy, tighter thickness tolerance, no thickness deviation.
2. Super smooth and delicate surface, no oxide scale, no rust spots, clean and bright appearance.
3. Improved material density and internal grain structure, higher hardness and better flatness.
4. Good straightness, not easy to deform during cutting, bending and stamping.
5. Easy for secondary processing such as polishing, drawing, laser cutting, welding and forming.

• Tensile Strength: ≥ 515 MPa
• Yield Strength: ≥ 205 MPa
• Elongation: ≥ 40%
• Hardness: Low hardness, good toughness and ductility
• Temperature Resistance: Excellent oxidation resistance at normal and medium high temperature
• Corrosion Resistance: Resists atmospheric corrosion, water corrosion, urban industrial environment corrosion, weak acid and weak alkali corrosion. Perfect anti-rust performance for indoor and outdoor long-term use.

• Strict surface inspection, no scratch, no pitting, no crack, no fold.
• Uniform color and luster, consistent surface texture of the whole coil and sheet.
• Thickness, width and length tolerance fully meet ASTM A240 standard.
• Flatness strictly controlled, suitable for high requirement decoration and structural use.

1. Standard Compliance Fully conforms to ASTM A240 standard, can pass third-party inspection such as SGS, BV, factory test certificate provided.
2. Super Corrosion & Rust Resistance 18% chromium and 8% nickel alloy formula provides outstanding anti-corrosion performance, not easy to rust in humid, rainy, coastal and industrial polluted areas.
3. Excellent Processability Good weldability, bendability, stamping performance, easy to process into various shapes and parts.
4. Durable & Low Maintenance High oxidation resistance, aging resistance, long service life, no need regular painting or anti-rust maintenance.
5. Complete Specifications & Flexible Service 4mm, 6mm regular thickness in large stock; support custom cutting, slitting, grinding, brushing, mirror polishing as customer requirements.
