SS304 plate, as a representative of austenitic stainless steel, has a classic composition ratio of 18%-20% chromium (Cr) and 8%-11% nickel (Ni), forming a dense passivation film, making its annual corrosion rate in 5% sodium chloride solution less than 0.002mm (carbon steel up to 0.1mm), salt spray test for more than 500 hours without red rust, and corrosion resistance is more than 5 times that of carbon steel. Its applicable temperature spans -196°Cto 800°C(long-term use is recommended to be ≤450°Cto avoid sensitization risks), thermal conductivity is 16.3 W/(m·K) (100°C, effectively inhibits thermal deformation, and is suitable for high-temperature equipment and low-temperature containers.
In terms of mechanical properties, the tensile strength is ≥520MPa, the yield strength is ≥205MPa, the elongation is ≥40% (can be increased to 2400MPa after cold rolling), and the hardness is ≤187HB. High elongation and low hardness give it excellent deep drawing performance (measured elongation ≥53%), which can withstand multiple stretching without cracking, and is suitable for harsh working conditions such as the lining of chemical equipment and high-temperature kiln components.
SS304 plate supports cold rolling/hot rolling/welding full process, non-magnetic (local weak magnetism after cold processing does not affect use). The surface provides 8 treatments such as 2B matte, BA bright surface, brushed (HL), frosted (NO.4), etc., to meet the needs of decoration and industrial sealing (such as graphite composite plate reinforcement layer). The thickness covers 0.2mm-115mm, the width is up to 1600mm, and non-standard sizes can be customized (such as 50mm extra thick plate).
Adopting 20-roller Sendzimir rolling mill, the thickness tolerance is controlled at ±0.005mm (hair 1/20), and the online spectrometer monitors the composition in real time (nickel-chromium fluctuation <0.5%). Annual production capacity exceeds 30,000 tons, with 1,000 tons of standing inventory, supporting 72-hour emergency shipments; delivery cycle for customized orders (such as special surfaces or sizes) is ≤7 days (industry average 15-20 days).
