304/304L Stainless Steel
WLD Stainless is a leading manufacturer, supplier and exporter of the stainless steel 304/304L in the shape of the pipe, tube, sheet, plate, bar, rod and other shapes like an angel, channel, circle, cut piece. 304 stainless steel is the most widely used, the largest consumption of Austenitic stainless steel is a grade based on 18-8 stainless steel. Austenite structure gives it good cold and hot processing properties, non-magnetic and good low-temperature properties. 304 stainless steel offers excellent intercrystalline corrosion resistance and good corrosion resistance in alkali solution and most of the organic acid, inorganic acid as well as the atmosphere, water vapor. 304L is a low-carbon version of 304 with slightly lower strength but significantly better inter crystal corrosion resistance than 304 stainless steel, sometimes can be an alternative material of 321 stainless steel.
