Durable Cold Rolled SUS304 Stainless Steel Sheet

Outstanding Durability & Mechanical Strength

As a cold-rolled product, it undergoes cold working processes (e.g., rolling at room temperature) that significantly enhance its mechanical properties. It boasts higher tensile strength (typically 515-795 MPa) and yield strength (≥205 MPa) compared to hot-rolled SUS304 sheets, along with excellent toughness and impact resistance. This durability enables it to withstand long-term mechanical stress, vibration, or minor impacts without deformation or cracking, making it suitable for load-bearing or high-wear applications.

Superior Corrosion & Rust Resistance

Leveraging the inherent properties of the SUS304 grade (containing 18% chromium and 8% nickel), it forms a dense, stable chromium oxide passive film on the surface. This film effectively blocks the penetration of oxygen, moisture, and mild corrosive media (e.g., household detergents, food acids, and atmospheric humidity). Even in humid environments (e.g., kitchens, bathrooms) or outdoor settings with low salinity, it resists rust, discoloration, and pitting corrosion, maintaining structural integrity for decades.

Precise Thickness & Smooth Surface Finish

Cold rolling eliminates the oxide scale and unevenness common in hot-rolled sheets, resulting in an ultra-smooth, uniform surface (typically with a 2B or BA finish). The 2B finish offers a matte, consistent texture ideal for general applications, while the BA (Bright Annealed) finish provides a near-mirror, glossy appearance for decorative uses. Additionally, cold rolling ensures tight thickness tolerance (usually ±0.01-0.05 mm), making the sheet suitable for precision manufacturing where dimensional accuracy is critical.

Excellent Formability & Processability

Despite its high strength, cold rolled SUS304 sheet retains good ductility and formability. It can be easily processed via cutting, bending, stamping, welding, and deep drawing without cracking or surface damage—even for complex shapes (e.g., stainless steel containers, hardware parts, or architectural components). This versatility allows it to adapt to diverse industrial and decorative needs, from small precision parts to large-area cladding.

Hygienic & Easy to Maintain

Its non-porous, smooth surface prevents the accumulation of dust, oil, bacteria, or food residues. This makes it compliant with hygiene standards for food processing, medical equipment, and catering facilities. Routine maintenance only requires wiping with a damp cloth and neutral detergent; no special coatings or harsh cleaners are needed, reducing long-term care costs.

Temperature Resistance

It maintains stable performance across a wide temperature range: it can withstand high temperatures up to 870°C (for short-term use) without losing structural strength, and remains tough at low temperatures (down to -196°C) without brittleness. This makes it suitable for applications involving thermal cycles, such as heat exchangers, oven liners, or refrigeration equipment parts.

Eco-Friendly & Recyclable

SUS304 stainless steel is 100% recyclable with no toxic emissions during production or use. The cold rolling process also consumes less energy compared to hot rolling, reducing its carbon footprint. Its long service life (often 20-30 years or more) further minimizes material waste, aligning with sustainable development goals.
