304/304L stainless steel plates are widely used in various industries due to their excellent properties. Here is some additional information about these stainless steel grades:
Composition: ASTM A240 Grade 304/304L stainless steel plates contain chromium (18-20%), nickel (8-10.5%), and a small amount of manganese, silicon, phosphorus, sulfur, and nitrogen. The low carbon content in Grade 304L (maximum 0.03%) helps to prevent sensitization during welding.
Austenitic Stainless Steel: Both Grade 304 and 304L belong to the austenitic stainless steel family. Austenitic stainless steels are non-magnetic and have a face-centered cubic crystal structure, which provides them with excellent formability, ductility, and toughness.
Corrosion Resistance: Grade 304/304L stainless steel plates exhibit good resistance to atmospheric corrosion and are suitable for various environments, including mildly oxidizing and reducing conditions. However, they may not be suitable for highly corrosive environments containing strong acids or chlorides.
Intergranular Corrosion Resistance: These grades have excellent resistance to intergranular corrosion, especially in the as-welded condition. This is achieved through the low carbon content and the addition of nitrogen, which helps to prevent the formation of chromium carbide precipitates along the grain boundaries.
Cryogenic Properties: ASTM A240 304/304L Dual Grade stainless steel plates exhibit good strength and toughness at cryogenic temperatures. This makes them suitable for applications that require resistance to low-temperature environments.
Dual Certification: It is common for Grade 304L to be dual certified as both 304 and 304L. This means that the material meets the mechanical properties of both grades, providing flexibility in its application.
In summary, ASTM A240 Grade 304/304L stainless steel plates are versatile materials that offer excellent corrosion resistance, intergranular corrosion resistance, and cryogenic properties. They are widely used in various industries for applications that require strength, toughness, and resistance to corrosion.
