A240 304L Plate,ASTM A240 304L (S30403) stainless steel plate,Sheet
ASTM A240 304L stainless steel plate is a standard 18-8 material – meaning it contains 18% chromium and 8% nickel. 304 Stainless steel plate is one of the most versatile stainless steel materials available. It has excellent forming and welding characteristics. Grades 304 and 304L stainless steel plate is dominant in the manufacture of stainless steel fabrications. 304 stainless steel plate can be braked formed into a variety of components for applications in the industrial, architectural, and transportation sectors. 304L is the low carbon version of 304.
