309S Stainless Steel Plate
309S Stainless Steel Plate Quick Details
309S stainless steel plate is also called as UNS S30908/W.Nr. 1.4833 stainless steel plate. We produce high quality stainless steel plates in a range of sizes.
309S stainless steel plate is austenitic chromium-nickel stainless steel that provides excellent corrosion resistance and heat resistance for many important applications.
309S stainless steel has high chromium and low nickel content, It can be utilized in sulfur containing atmospheres up to 1000 degree. 309S stainless steel plate is widely used in important fields such as boilers, energy (nuclear power, thermal power, fuel cells), industrial furnaces, incinerators, heating furnaces, chemical industry, petrochemicals industry, etc.
As a commonly used stainless steel plate product, 309S stainless steel plate is manufactured by hot rolled coils, resulting in sheet thicknesses typically over 3mm. Compared to cold rolled stainless steel sheet, these hot rolled plates have a whiter finish.
At HZW, we supply high-quality 309S plates in various sizes and thicknesses, with custom cutting, surface treatment, and global delivery options available to meet your specific project needs.
