309/309S Stainless Steel Plate
309 stainless steel is an austenitic stainless steel containing higher chromium and nickel content. 309 stainless steel has excellent corrosion resistance in various corrosive media, including acid, alkali, salt and other solutions, as well as organic solvents. It can still maintain good corrosion resistance at high temperatures. Moreover, it has good high-temperature strength and creep properties and can work stably for a long time in high-temperature environments. It is suitable for high-temperature equipment in aviation, chemical industry and other fields. 309 stainless steel can be formed and welded through various processing methods and has good processing performance. Lastly, 309 stainless steel is non-magnetic and suitable for manufacturing parts and components without magnetic requirements.

详情标题2-生产线


This stainless steel plate production line integrates precision rolling, heat treatment, and finishing processes to ensure products meet high standards in both intrinsic properties and surface quality. The hot rolling section utilizes high-power reversible roughing mills and multi-stand finishing mill groups, enabling efficient rolling of various wide slabs. Through short stress path design and horizontal/vertical alternating layouts, it achieves precise control over plate thickness and flatness. The core heat treatment process employs roller hearth solution furnaces with online quenching systems to optimize the material's metallurgical structure, consistently enhancing corrosion resistance and mechanical properties. The finishing section is equipped with multi-roll levelers, high-power shot blasting units, and phased array ultrasonic and eddy current combined inspection systems, comprehensively ensuring plate flatness, surface cleanliness, and internal quality. The entire line supports various stainless steel grades and customized cutting, meeting stringent requirements in architectural decoration, chemical equipment, high-end appliances, and other fields.
