304H Stainless Steel Plate Supplier

Stainless steel 304H sheet, plate, and coil are high-temperature grades of the 304 family, known for excellent strength and oxidation resistance. This grade contains higher carbon content, which improves heat resistance and mechanical strength at elevated temperatures. Preston Pipes & Alloys is a leading manufacturer and supplier of stainless steel 304H products, offering quality materials that meet global standards. It contains elements such as chromium, nickel, carbon, manganese, silicon, phosphorus, and sulfur in specific proportions to create a perfect combination of strength and corrosion resistance. It possesses a tensile strength of at least 75 ksi, a yield strength of 30 ksi and an elongation of 40%, which makes it both tough and malleable. The material remains stable in both hot, and corrosive environments, so it may be utilized for essential projects.

Stainless steel 304H coil, sheet, and plate offer excellent resistance to corrosion, high strength and ease of fabrication. The material works well in high temperature environments while retaining its structural integrity. It is resistant to scaling and retains toughness in a broad array of temperatures. These give it application in the petrochemical, oil and gas, chemical, power generation, energy, pharmaceutical, pulp and paper, food processing, aerospace and refining sectors. As reliable 304H stainless steel sheet suppliers, we emphasize providing products that meet stringent service requirements while maintaining dimensional precision and uniform quality for all applications.

The 304H stainless steel plate, sheet, and coil meets the ASTM / ASME SA240 specifications. The products are available in thicknesses ranging from 5 mm to 150 mm, widths of 1000 mm, 1219 mm, 1250 mm, 1500 mm, and 2000 mm, and lengths up to 6000 mm. Coil thickness ranges from 0.3 mm to 10 mm, cold-rolled sheets from 0.3 mm to 6 mm, and hot-rolled sheets or plates from 3.0 mm to 20 mm. Available hardness complies with ASME A and NACE MR 175 requirements. Finishes include hot rolled (HR) and cold rolled (CR), and forms include coils, foils, rolls, plain sheets, shim sheets, and perforated sheets. Each dimension and finish option supports varied industrial needs while ensuring strength and performance.

Every 304H stainless steel plate, sheet, and coil undergoes strict quality checks, including dimensional inspection, mechanical testing, and corrosion resistance evaluation. The EN 10204/3.2B certificates are issued for the mill test certificates to ensure traceability and compliance. International safety standards are followed in packaging with wooden boxes, plastic bags, and steel strip bundles, or as specified by the customer, to avoid damage in transit. With consistent quality, accurate specifications, and prompt delivery, the products are ready to meet the demands of critical industrial processes.
