Stainless Steel Plate Product Classification
Cunrui offers stainless steel plate in different grades for applications ranging from general fabrication to high-temperature, chemical, marine, and heavy industrial environments.
304 Stainless Steel Plate
304 stainless steel plate is a widely specified austenitic stainless steel for general industrial applications. It provides a practical combination of corrosion resistance, formability, weldability, and mechanical performance.
316L Stainless Steel Plate
316L stainless steel plate is selected when improved corrosion resistance is required, particularly in environments involving chlorides, chemicals, or other corrosive media. Its low carbon content also makes it suitable for welded structures where corrosion resistance after welding is important.
321 Stainless Steel Plate
321 stainless steel plate is a titanium-stabilized austenitic grade developed for applications involving elevated temperatures. It provides good resistance to intergranular corrosion after exposure to elevated temperatures and is suitable for welded components.
310S Stainless Steel Plate
310S stainless steel plate is designed for high-temperature applications requiring good oxidation resistance and thermal stability. It is commonly used in furnace components, heat-treatment equipment, thermal processing systems, and high-temperature industrial structures.
309 Stainless Steel Plate
309 stainless steel plate provides good oxidation resistance and mechanical performance at elevated temperatures. It is suitable for furnace equipment, heat exchangers, thermal processing systems, and other high-temperature applications.
2205 Duplex Stainless Steel Plate
2205 duplex stainless steel plate combines high mechanical strength with strong corrosion resistance. Its duplex metallurgical structure makes it suitable for demanding applications where both strength and resistance to corrosive environments are important.
904L Stainless Steel Plate
904L stainless steel plate is a high-alloy austenitic stainless steel developed for demanding corrosive environments. It is considered for chemical processing, sulfuric acid applications, pollution-control equipment, and other projects requiring enhanced corrosion resistance.
Other Stainless Steel Plate Grades
Additional stainless steel grades can be supplied according to application requirements, including different austenitic, ferritic, martensitic, and duplex stainless steel materials.
For a specific grade not listed above, customers can provide the required material designation or standard for confirmation.
