304 / 304L Stainless Steel Plate

304 and 304L stainless steel plates are part of the austenitic family of stainless steel and they are one of the most versatile and widely used varieties of stainless plate. They are a relatively low cost stainless product and used in a variety of applications. 304 grades have excellent low temperature properties and respond well to hardening by cold working. 304 stainless steel plate grades have good welding characteristics and post weld annealing is not normally required to restore performance. 304 SS plates have excellent corrosion resistance in a variety of different media. Typical specifications for 304 and 304L ss plates are ASTM A-240, ASME SA -240 and A666.
