About 304/304L/304H Coil
Stainless Steel 304, 304L, and 304H belong to the austenitic 300 series and are selected based on specific application needs. SS 304 is used for general-purpose applications where balanced strength and corrosion resistance are required. SS 304L, with its lower carbon content, is preferred in welding work to reduce the risk of corrosion in welded areas. SS 304H, on the other hand, is used in applications involving higher temperatures due to its improved strength under heat.
Choosing the correct grade depends on factors such as operating temperature, fabrication method, and exposure conditions in the working environment.
