AISI/SS 304 / 304L Plate is the part of SS austenitic grade. These are the most versatile grade of SS plates with a variety of attributes. These are relatively low-cost SS product with a variety of applications. Plates have excellent low-temperature properties and best for cold working applications. These plates are easily weldable with conventional techniques. Plates are being processed with the selection of finest raw materials to gain high service life. Most importantly, heat treatment process enhances the strength of plates.
