304 Stainless Steel Plate Description

304 stainless steel is a kind of universal stainless steel material, rust resistance than 200 series of stainless steel material is stronger. High temperature resistance is also better, can be as high as 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it is concluded in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of less than or equal to 65% of the boiling temperature. It also has good corrosion resistance to alkali solution and most organic and inorganic acids.

304 stainless steel plate is a highly versatile and widely used material in modern industry, prized for its superior corrosion resistance, excellent mechanical properties, and adaptability to various applications. Compared with 200 series stainless steels, 304 exhibits stronger rust resistance and better high-temperature performance, withstanding temperatures up to 1000–1200°C. This makes it suitable for both high-temperature industrial processes and applications requiring long-term durability under harsh environmental conditions. Its exceptional corrosion resistance also extends to oxidizing acids such as nitric acid (≤65% concentration at boiling temperature), alkali solutions, and most organic and inorganic acids, ensuring longevity and reliability in chemically aggressive environments.

The 304 stainless steel plate is available in a wide range of thicknesses from 0.3mm to 200mm and can be customized in length and width to meet specific project requirements. Standard lengths include 2000mm, 2438mm, 3000mm, 5800mm, 6000mm, and even 12000mm, while widths vary from 40mm up to 3500mm depending on industrial needs. The plates are manufactured according to international standards, including ASTM, AISI, JIS, GB, DIN, and EN, ensuring consistency and global compatibility. Various surface finishes are available, such as BA, 2B, NO.1, NO.4, 4K, HL, and 8K, allowing manufacturers and designers to choose surfaces suitable for aesthetic appeal, hygiene requirements, or functional performance in industrial environments.

Mechanical properties of 304 stainless steel plate include a tensile strength of ≥520 MPa, yield strength of ≥205 MPa, elongation of ≥40%, and hardness values up to 187HB, 90HRB, or 200HV. These properties provide excellent strength, ductility, and toughness, allowing the material to perform reliably under mechanical stress. Physical characteristics, such as a density of 8.03 g/cm³, modulus of elasticity of 193 GPa, thermal expansion coefficient of 16.9×10⁻⁶/°C, thermal conductivity of 16.2 W/m·K, and resistivity of 72 μΩ·cm, further enhance its suitability for high-temperature, high-stress, and electrically conductive applications.

304 stainless steel plates are widely applied across numerous industries. In the construction and architectural sectors, they are used for building facades, roofing, handrails, and decorative panels due to their aesthetic appeal, durability, and corrosion resistance. In the food and beverage industry, 304 plates are used in processing equipment, storage tanks, kitchen appliances, and packaging machinery where hygiene, cleanability, and chemical resistance are essential. The medical and pharmaceutical sectors rely on 304 stainless steel plates for equipment, surgical instruments, and cleanroom components due to their biocompatibility and resistance to contamination.

Additionally, 304 stainless steel plates are utilized in transportation industries, including trains, airplanes, and vehicles, as well as in the production of conveyor belts, bolts, nuts, springs, and screens, where mechanical strength, corrosion resistance, and reliability are crucial. The plates’ ability to withstand repeated mechanical deformation, high temperatures, and chemical exposure makes them ideal for demanding industrial processes.

Produced through hot and cold rolling techniques, 304 stainless steel plates can be further processed with edge treatments such as edging or trimming to meet precise manufacturing requirements. Certified by ISO, SGS, and BV, 304 stainless steel plates meet rigorous international quality standards, ensuring reliability, performance, and safety.
