ASTM A240 439 Stainless Steel Plate Price Per Ton
Leave a message
Are you looking for affordable, high-quality, and durable ASTM A240 439 stainless steel plates? Our 439 stainless steel plates comply with the ASTM A240 standard, offering excellent corrosion resistance, oxidation resistance, and superior formability, suitable for a wide range of industrial applications.
Our ASTM A240 439 stainless steel plates are made from chromium alloy, making them ideal for applications requiring corrosion resistance, heat resistance, and high weldability. With a low thermal expansion coefficient (approximately 10.8×10⁻⁶/°C) and good thermal conductivity (approximately 26-28 W/(m·K)), they are suitable for applications with significant temperature variations. The surface is available in 2B cold-rolled matte, BA bright annealed, or No.4 brushed finishes, presenting a uniform, clean texture that is easy to clean and aesthetically pleasing. Thickness ranges from 0.3-6.0mm, and widths up to 1500-2000mm, supporting custom cutting and bulk supply. Offering a higher cost-performance ratio than 304 stainless steel, they are widely used in automotive exhaust systems, household appliances, architectural decoration, kitchen equipment, and industrial heat exchangers.
